On July 25, 2023, a Brussels court convicted Salah Abdeslam, Mohamed Abrini, and six others of complicity in the March 2016 Brussels bombings. The court also convicted Oussama Atar, Osama Krayem, Ali El Haddad Asufi, and Bilal El Makhoukhi. Two men, a Tunisian and a Rwandan, were cleared of murder but were convicted of taking part in terrorist activities, along with the other six. Brothers Smail and Ibrahim Farisi were cleared of all charges. The sentencing phase of the trial is expected to begin in September 2023. The March 2016 attacks—in which two suicide bombers launched attacks at Brussels’ Zaventem airport and another struck the city’s metro system—killed 32 people in total. Eight of the defendants were accused of supporting a terrorist cell or supplying the Brussels attackers with weapons and logistical assistance. Atar, the ringleader of the bombings, was allegedly a senior figure in ISIS’s intelligence service. Atar was tried in absentia as he purportedly died while fighting in Syria in 2017. During the defendants’ first preliminary hearing on September 12, 2022, Abdeslam refused to take the stand as he claimed the glass-enclosed cubicles used in the trial prevented the defendants from being able to effectively speak with their lawyers. On December 12, six defendants refused to attend the bombing trial due to unfair security measures, which included two strip searches a day.

Brussels continues to grapple with terrorist incidents. On November 11, 2022, a knife-wielding man shouted “Allahu Akbar”—the Arabic phrase for “God is great”—before fatally stabbing one officer and injuring another near Brussels North station. The assailant was shot at by another officer from a different patrol and was taken to the hospital. According to officials, the suspect, Yassine M., had been in jail between 2013 and 2019 for non-terror offences and was on a violent extremist watch list. (Sources: Sky News, BBC News)
Islamic terrorism is not the only threat facing Belgium as police have been alerted of far-right activity. on September 28, 2022, Belgian police launched anti-terror raids targeting suspected far-right extremists in Antwerp and Ghent. According to authorities, the raid was conducted following an investigation of “the preparation of a terrorist attack and the violation of the legislation on weapons.” One suspect was killed following an exchange of fire, and according to Belgian broadcaster VRT, the man was reportedly a gold and silver trader who collected weapons and military items.

On the morning of March 22, 2016, two suicide bombers—later identified as former ISIS fighter Ibrahim el-Bakraoui and suspected bomb-maker Najim Laachraoui—launched attacks at Zaventem airport, killing 16 people. An hour later, another suicide bomber—identified as Ibrahim’s brother Khalid el-Bakraoui—struck the city’s metro system, killing 16 people at the Maelbeek station. In the wake of the attacks, Belgium temporarily raised its national threat level to the highest level (four), closed the metro system, evacuated the airport, and shut down two nuclear power plants. The attacks also propelled the country into a weeks-long manhunt for attacks suspect Mohamed Abrini, who was arrested alongside several co-conspirators on April 8, 2016. (Sources: Reuters, Guardian, New York Times, Guardian, CNN, New York Times)
The Brussels terrorist attacks were the deadliest in the country’s history. Several government representatives resigned or offered to resign, after it emerged that the government had failed to follow through on leads flagged by the Turkish government and anticipate major national security lapses flagged by the European Union. Turkey had previously arrested one of the bombers—Ibrahim el-Bakraoui—and deported him to the Netherlands on suspicion of being a foreign fighter. Turkish President Recep Tayyip Erdoğan said that he had alerted Belgium of the arrest, but that Belgian authorities did not effectively pursue the lead. (Sources: Politico, Reuters, Atlantic, Independent, BuzzFeed, New York Times, U.N., Express.be, Le Soir, New York Times, BuzzFeed, New York Times, Telegraph)
The attacks highlighted Belgium’s struggle to meet surveillance demands. More than 500 Belgians are suspected to have left the country to serve as foreign terrorist fighters abroad, according to the Belgian government. As of January 2018, the government suspected that at least 100 foreign fighters had returned to the country. Other factors reportedly hindering Belgium’s intelligence apparatus are the country’s language divide and overall budgetary constraints. As one anonymous official told media, “We just don’t have the people… and, frankly, we don’t have the infrastructure to properly investigate or monitor hundreds of individuals suspected of terror links, as well as pursue the hundreds of open files and investigations we have.” (Sources: International Centre for Counter-Terrorism - The Hague, Soufan Group, Deutsche Welle, Politico, Express.be, United Nations, Pieter van Ostayen, New York Times, BuzzFeed, New York Times, U.S. State Department)
Despite Belgium’s efforts to improve its national security since the Brussels attacks, the country has continued to experience lone-wolf terror attacks. On August 7, 2016, ISIS claimed an attack in which a machete-wielding man wounded two Belgian policewomen in the city of Charleroi. On August 22, 2016, a machete-wielding woman attacked passengers on a bus in Brussels, wounding three people. On October 5, 2016, a knife-wielding assailant stabbed two policemen in Brussels. On March 23, 2017, a man was intercepted while driving at high-speed on De Meir, the major shopping street in Antwerp. The incident—while not producing casualties or injuries—bore the hallmarks of similar vehicular attacks in Nice, Ohio, Germany, and London. On November 20, 2018, a knife-wielding assailant stabbed a police officer in the city center of Brussels while allegedly shouting “allahu akbar.” (Sources: Reuters, Telegraph, Independent, Wall Street Journal, CNN, BBC News, Express)
Radicalization and Foreign Fighters
According to an October 2015 U.N. report, jihadist recruitment in Belgium is typically conducted through informal networks of friends and family, as well as through social media outlets online. Friends and family members who are in Syria are compensated monetarily for their recruiting efforts, given anywhere between $2,000 to $10,000 based on the number of people they are able to recruit to terror, the specialized skills of a given recruit, and whether their recruits are able to find a spouse. (Sources: United Nations, Express.be)
The October 2015 U.N. report is consistent with trends that emerged during Belgium’s Sharia4Belgium trial, wherein the Islamist group was accused—and ultimately convicted—of radicalizing, recruiting, and facilitating travel for a number of Belgium’s foreign fighters. According to Belgian authorities, Sharia4Belgium sent its first jihadist to Syria in May 2012. The group sent 70 of its members to Syria by March 2013. Of 46 Belgian foreign fighters prosecuted as of October 2015, all 46 belonged to Sharia4Belgium. (Sources: Nieuwsblad.be, Humo.be, De Standaard, Wall Street Journal, Reuters, United Nations)
Sharia4Belgium—which officially disbanded in 2012—aspired to institute sharia (Islamic law) in Belgium. The group was headed by notorious Islamist Fouad Belkacem, known to have made extreme and violent statements, including advocating the death penalty for gays. In 2011, Belkacem was called to a correctional court for incitement to hate. He has a history of arrests for violence and burglary dating back to 2002. (Sources: Nieuwsblad.be, Humo.be, De Standaard, Wall Street Journal, Reuters)
The Brussels suburb of Molenbeek has specifically come under scrutiny, and is known for a set of conditions believed to be conducive to radicalization. As of 2017, Molenbeek housed 49 terror suspects per 100,000 people. The ratio in the rest of Belgium was three out of 100,000. As of 2015, Molenbeek’s unemployment rates almost four times higher than the rest of Belgium’s. As of 2017, Molenbeek housed 26 times as many mosques per 100,000 people than the rest of Belgium, and more than twice as many foreign residents per 100,000 people than the rest of Belgium. (Source: Wall Street Journal)
Of the 413 foreign fighters who left Belgium in 2015 and 2016, 47 (11 percent) were from Molenbeek. November 2015 assailants Abdelhamid Abaaoud, Salah Abdeslam, and Ibrahim Abdeslam were all raised in Molenbeek. Suspected August 2015 train assailant Ayoub El Khazzani also resided in the Molenbeek neighborhood, and May 2014 assailant Mehdi Nemmouche is believed to have passed through Molenbeek. Belgian Prime Minister Charles Michel has called for a crackdown on the Molenbeek borough, saying, “Almost every time, there is a link to Molenbeek.” The mayor of Molenbeek has herself called the borough “a breeding ground for violence.” As of February 2018, authorities suspect some two dozen Molenbeek families of fomenting radicalization. (Sources: France24, Guardian, New York Times, Reuters, New York Times, Wall Street Journal)
The Molenbeek government has taken several steps to fight radicalization in the suburb. Authorities have increased monitoring of extremist messaging in mosques. At least five mosques and schools have been shut down since 2016. Some groups in Molenbeek have sought to fight radicalization by breaking down preconceptions about Muslims. Authorities have also increased the number of surveillance systems and the number of officials monitoring suspected extremists. In 2017, the Get Me collective launched a project called “Hipster/Muslim: the New West.” The photo project saw similar looking individuals swap hipster and traditional Muslim clothing. After the March 2016 terror attacks in Brussels, an organization called Brussels Sounds Good launched with the goal of increasing cross-cultural understanding. That December, the group led a campaign of Belgian Muslims sending out Christmas greetings over social media to show respect for other religions. (Sources: Deutsche Welle, Deutsche Welle, Wall Street Journal)
The Belgian government has also sought to monitor and decrease extremist messaging in the country’s mosques. The Grand Mosque of Brussels is the country’s largest. After Belgian Muslims played primary roles in major terror attacks in November 2015 and March 2016, Belgian officials accused the mosque’s imams of espousing radical messages. The mosque is administered by the Saudi-based World Muslim League, which critics also accuse of espousing extremist messages. Belgium’s migration agency previously sought to expel the mosque’s primary imam, an Egyptian cleric named Abdelhadi Sewif, for preaching an ultraconservative version of Islam, but a Belgian court blocked his deportation. The Saudi government maintains a 99-year, rent-free lease on the mosque, which was a goodwill gesture from Belgium’s king to the Saudi monarchy in 1969. In November 2017, a Belgian parliamentary commission recommended breaking the lease. According to commission member Servais Verherstraeten, there is a “perception that there is something to hide in the most important mosque in the country.” Belgium terminated the lease in March 2018. A government statement said it is seeking “to put an end to foreign interference in the way Islam is taught in Belgium.” The decision gave the World Muslim League a year to vacate, after which the government would turn administration over to the Muslim Executive, Belgium’s government-backed umbrella group for the country’s Muslims. Following the announcement, Interior Minister Jan Jambon tweeted, “With this, we end Salafist, violent extremist influences.” (Sources: Washington Post, Washington Post, Washington Post)
Belgium’s prisons have also been a source of radicalization. According to Belgium’s State Security Service, nearly 5 percent of all prisoners in Belgium—450 prisoners in all—posed a radicalization threat as of 2017. Indeed, at least one notable Belgian jihadist is believed to have been radicalized in a Belgian prison: Abdelhamid Abaaoud, one of the masterminds of the November 13, 2015, ISIS attacks in Paris. After Benjamin Herman killed three people and took a fourth hostage while on 48-hour prison leave in Liège, authorities suspected he was radicalized in prison. Police shot and killed Herman, and ISIS called him one of a “soldier of the Islamic state.” (Sources: La Libre, Reuters, New York Times)
Other foreign suspects with ties to Belgian jihadist networks carry a prior criminal record, including:
- Ibrahim el-Bakraoui, suspect in the March 22, 2016, bombing in Belgium’s Zaventem airport. In 2010, el-Bakraoui was sentenced to nine years in prison after robbing a currency exchange office and shooting at police.
- Khalid el-Bakraoui, suspect in the March 22, 2016, bombing in Brussels’ Maelbeek metro station. In 2011, el-Bakraoui was sentenced on charges of an attempted auto theft and illegal possession of assault rifles.
- Salah Abdeslam, suspect in the November 13, 2015, attacks in Paris.
- Ibrahim Abdeslam, suspect in the November 13, 2015, attacks in Paris.
- Paris attacks suspect Ismaël Omar Mostefaï, arrested as a youth for various petty offenses but reportedly never jailed. Mostefaï was part of Abaaoud’s jihadist cell and is believed to have been radicalized by a Belgian preacher in France. Mostefaï attacked concertgoers at Paris’s Bataclan concert hall.
- August 2015 alleged train gunman Ayoub El Khazzani, who had a history of drug trafficking. El Khazzani resided in France’s Molenbeek neighborhood and was reportedly linked to the jihadist cell targeted in Belgium’s January 2015 police raid in Verviers. He is suspected of attempting a gun attack on a high speed Thalys train from Amsterdam to France.
- January 2015 gunman Amedy Coulibaly, a convicted armed robber and drug dealer whose arrest history dates back to 2001. Coulibaly reportedly bought weapons for his intended assault from a dealer in Molenbeek before killing a police officer, and later attacking a kosher supermarket, killing four.
- May 2014 gunman Mehdi Nemmouche, imprisoned time and again in France for a range of charges including theft, robbery, and driving without a license. After returning to Europe from Syria, Nemmouche attacked the Jewish Museum of Brussels, killing four.
Following the example of neighboring France, Belgium has begun to quarantine prisoners who they believe pose a radicalizing danger. France ended its prison isolation experiment in 2016, however, after finding that their methods had the opposite intended effect, deepening radicalization networks within prisons. (Sources: La Libre, Wall Street Journal)
Since the announcement in October 2016, however, Belgium has continued to isolate radicalized prisoners from the rest of the prison population. According to Belgian officials, the isolated areas at Hasselt and Ittre prison house around 20 people in all. According to Belgium’s State Security Service Administrator-General Jaak Raes, however, there are already signs that the isolation method may not be working, as inmates are often able to communicate with each other through their cells in Arabic, which Belgian guards do not typically understand. One of the isolated inmates is Moroccan recruiter Khalid Zerkani, who has been linked to at least 22 known extremists. (Source: La Dernière Heure, Washington Post, Wall Street Journal)
Belgium’s Coordination Unit for Threat Analysis (OCAM) maintains the country’s terror-threat level on a scale of one to four. As of 2022, the threat level remained at 2 or “medium” threat. OCAM releases an annual report that details terrorist and extremist threats on the country, and on December 2, 2022, OCAM released the findings from its 2021 report. According to the report, Belgium received 218 terrorist and extremist threats, with 50 percent of the threats rated as low-level and a third considered medium-level. One threat was considered serious and imminent, involving, Jürgen Conings, an armed far-right extremist former military man. In May and June 2021, Congings made threats against Belgian politicians and against virologist Marc Van Ranst. Furthermore, the report noted that Belgium has prioritized the monitoring of 64 jihadists, 64 right-wing extremists, and 14 left-wing extremists. (Sources: Brussels Times, Politico)
Returning foreign fighters pose a deadly threat to Belgium and its neighbors. Belgian officials estimate that at least 125 foreign fighters have returned to the country. Belgium reportedly has one of the highest numbers of returning ISIS fighter in Europe. Among Belgium’s returning ISIS fighters were the November 2015 Paris attacks mastermind Abdelhamid Abaaoud and at least one of the November 2015 assailants, Ismaël Omar Mostefaï. Mehdi Nemmouche—the French national who carried out the May 2014 attack on the Jewish Museum of Brussels—had also returned to Europe after fighting with ISIS. (Sources: Albawaba News, Telegraph, Telegraph)
Belgium has produced the greatest number of European foreign fighters per capita in Iraq and Syria. In April 2015, Belgian newspaper Le Soir quoted one analyst saying that two Belgian foreign fighters were traveling to Iraq and Syria each week. A U.N. delegation in October 2015 estimated the number of Belgian foreign fighters at 500, though government officials speaking in November 2015 claimed that the figure was around 470. In September 2016, one expert put the high-end estimate of Belgian foreign fighters at more than 614 people. As of mid-2016, more than 30 people returning from the conflict zone have been tried or convicted on terrorism-related charges. (Sources: Le Soir, Le Soir, Economist, Express.be, Le Vif, Soufan Group, Pieter van Ostayen, Deutsche Welle, La Libre)
Belgian officials believe that 413 Belgians left to fight in Syria in 2015 and 2016. The government reported no foreign fighters leaving Belgium in 2017. In February 2018, authorities believed one-third of those 413 were dead, one-third remained in the Middle East, and one-third had returned to Belgium. In February 2020, estimates maintained that 125 Belgian fighters have returned home. (Sources: Wall Street Journal, Deutsche Welle, Foreign Policy Research Institute)
Additional reports in 2019 claim 602 Belgian citizens were believed to have joined or were affiliated with ISIS in Iraq and Syria. Of that figure, 93 of those supporters were women. Following the collapse of ISIS’s caliphate, two women were returned to Belgium and charged in June 2020 and one woman was charged in July 2020. Additionally on July 16, 2021, Belgium repatriated six mothers from al-Roj camp. Upon their arrival to Belgium, the women were handed over to the jurisdiction of the Belgian court services and were convicted of participating in the activities of a terrorist group. Furthermore, on June 21, 2022, Belgium repatriated six women and 16 children from al-Hol camp in northeastern Syria. Upon their arrival to Belgium, the women were handed over to the jurisdiction of the Belgian court services and were convicted of participating in the activities of a terrorist group.

Major Extremist and Terrorist Incidents
March 2016 Airport and Metro Attacks
On the morning of March 22, 2016, two suicide bombers—later identified as ex-convict Ibrahim el-Bakraoui and suspected bomb-maker Najim Laachraoui—launched attacks at Brussels’ Zaventem airport, killing 16 people. An hour later, another suicide bomber—identified as Khalid el-Bakraoui—struck the city’s metro system, killing 16 people at the Maelbeek station. Following the attacks, Belgian officials also arrested two other suspects who had appeared on the crime scene. Mohamed Abrini and Osama Krayem were caught on camera before the Zaventem airport attack and Maelbeek metro attack, respectively. Abrini reportedly admitted that he had intended to carry out a third suicide bomb attack at Zaventem airport. (Sources: Reuters, Guardian, New York Times, BBC News)
Also reportedly linked to the attacks was Khalid Zerkani, also known as “Papa Noel.” Zerkani is allegedly an ISIS recruiter based in Belgium, and has been linked to at least 22 extremists, including March 2016 suspects Najim Laachraoui and Mohamed Abrini, as well as November 2015 Paris suspects Abdelhamid Abaaoud and Salah Abdeslam. (Source: Telegraph, New York Times)
On November 29, 2019, French investigators, in cooperation with Belgian police, released a 561-page indictment that concludes Belgian national, Oussama Atar—alias Abu Ahmed, was responsible for planning a series of attacks in Paris and Brussels in 2015 and 2016. The Paris incidents include the Stade de France and Bataclan theatre attacks in November 2015 where over 130 people were killed. The attacks in Belgium include one failed attack in Verviers in January 2015, one thwarted attack on a Thalys train in August 2015, and the March 2016 attack in Brussels. Atar, along with his cousin Khalid el-Bakraoui, set up an ISIS cell in Belgium in 2014, and it is suspected that he later relocated to Syria to plan attacks across the Middle East. It is alleged Atar was a close associate of Abu Muhammad al-Adnani, then the spokesman of ISIS. Atar was later given authority to plan attacks across Europe. According to the indictment, Atar has since been killed in Syria. On February 5, 2020, it was reported that prosecutors in Belgium sought to bring Atar’s seven accomplices to the country’s highest court for their role in the 2016 Brussels attacks. One suspect, Salah Abdeslam, is already in French jail due to his role in the Paris 2015 attack that killed 131 people. Abdeslam has already been sentenced to 20 years in prison in Belgium for injuring three officers in a shootout before escaping and later being captured in France. (Sources: Brussels Times, Financial Times, The National, BBC News)
On May 1, 2021, a Belgian court announced that 10 suspects would stand trial for the 2016 Brussels terror attacks. However, one of the defendants, Oussama Atar, was presumably killed in Syria and would be tried in absentia. Prosecutors had previously requested that eight of the defendants face the Criminal Court of Assizes—a court where the most serious crimes are tried—on charges of assassinations and attempted assassinations in a terrorism context, and for membership of a terror. On September 12, 2022, Salah Abdeslam and eight other suspected members of ISIS appeared at a Brussels court where they faced charges for their connection to the March 2016 Brussels bombings. Abdeslam refused to take the stand as he claimed the glass-enclosed cubicles used in the trial prevent the defendants from being able to effectively speak with their lawyers. On December 5, 2022, the trial of the 2016 Brussels terror attacks commenced at a Brussels court. (Sources: Deutsch Welle, Agence France Presse, Barron’s, Euro News, National)
On July 25, 2023, a Brussels court convicted Abdeslam, Mohamed Abrini, Oussama Atar, Osama Krayem, Ali El Haddad Asufi, and Bilal El Makhoukhi of complicity in the March 2016 Brussels bombings. Two men, a Tunisian and a Rwandan, were cleared of murder but were convicted of taking part in terrorist activities, along with the other six.

Before the March 2016 attacks, Belgium suffered its most recent terrorist attack on Belgian soil in May 2014, when French national and ISIS fighter Mehdi Nemmouche killed four people at the Jewish Museum in Brussels. The May 2014 attack and the subsequent 2015 attacks in France that were heavily linked to Belgian jihadist activity had major impacts on Belgium, spurring new debate on the threats of Islamic extremism and returning foreign fighters.
On March 4, 2018, Belgian police arrested eight people in Molenbeek during a counterterrorism raid based on suspicions of a forthcoming terrorist attack. Since the March 2016 Brussels attacks, Belgium has devoted more than $400 million to improving its capacity to investigate and preempt terrorist attacks. Belgium has conducted a series of police raids on suspected terror cells around the country, including in Molenbeek, Brussels, Forest, and Schaerbeek, Anderlecht, Bruges, and Laeken. Prior to the March 2016 attacks, Belgium had dismantled the foreign fighter pipeline Sharia4Belgium in Antwerp in one of the largest terror trials in the country’s history. Following the January 2015 Charlie Hebdo attacks in neighboring France, the government proposed 30 counterterrorism measures, at least 26 of which have been implemented as of March 2017. These measures include eliminating unregistered prepaid SIM cards for cellular phones and empowering the government to suspend passports of terrorism suspects without judicial approval. Human Rights Watch and other civil rights groups have accused the Belgian government of trampling on human rights in the name of security since the 2015 Paris and 2016 Brussels attacks. (Sources: Sun Daily, Le Soir, La Libre, Fox News, New York Times, BBC News, Politico, Economist, Human Rights Watch, U.S. State Department)
In early 2017, the Belgian parliament passed a law empowering the government to deport legal foreign residents suspected of engaging in terrorism, without criminal charge or a judicial ruling. Civil rights groups have contested the law as a threat to civil liberties. In particular, Human Rights Watch has accused the Belgian government of “abusive” new policies that overstep its authority. In March 2018, the Belgian government began discussing a proposed law to allow police to raid immigrants’ homes and deport people whose asylum requests had been denied. Belgian citizens reportedly shelter 500 illegal immigrants each night. Prime Minister Charles Michel called the proposed law “a matter of public order and security.” (Sources: New York Times, Newsweek, Washington Post)
Prior to these efforts, however, Belgium has historically tended to opt for less law-enforcement oriented solutions to the threat of terrorism, seeking to instead address terrorism’s “root causes” in an effort to combat the threat without unnecessarily stigmatizing the Muslim community. As Belgium looks to investigate terror suspect leads and dismantle extremist networks, one anonymous official has admitted that the police is stretched too thin to adequately address the terrorist threat. The U.S. State Department validated this concern in its 2016 Country Reports on Terrorism, noting that Belgium “still faced resource and institutional constraints” in its efforts to combat the threat of domestic terrorism. Due in part to Belgium’s decentralized government structure, the country suffers from poor information-sharing practices among its various government agencies. As the U.S. State Department notes, Belgium also continues to suffer from an over-burdened court system that prevents individuals from engaging in plea agreements, and levies “relatively light sentences” on individuals convicted for terrorism-related offenses. (Sources: Egmont, Belgium’s Ministry of Foreign Affairs, BuzzFeed, U.S. State Department)
Belgium’s Coordination Unit for Threat Analysis (OCAM) maintains the country’s terror-threat level on a scale of one to four. The country has largely maintained its second-highest level of three, indicating an attack is “possible and likely,” since police broke up a terror cell in Verviers in January 2015. The government briefly raised the terror threat level to four, indicating a “serious and imminent threat,” in the wake of the March 2016 terror attacks in Brussels. In January 2018, Belgium lowered its threat level to two, indicating that an attack is “unlikely,” though it maintained the level three in specific areas. In announcing the lower threat level in January 2018, the government also announced that military patrols would continue around high-target areas, including nuclear power stations and synagogues. (Sources: Kingdom of Belgium, Politico, Agence France-Presse)
In 2015, Belgium established a task force to create a national counterterrorism and counter-extremism strategy. Historically, however, Belgium has tread cautiously around the word terrorism and worked to incorporate empathy into its counterterrorism efforts. Belgium’s 2003 Terrorist Offences Act tread cautiously around the concept of terrorism, criminalizing participation in terrorist groups while noting that an “organization whose real purpose is solely of a… religious nature… cannot, as such, be considered a terrorist group.” According to Alain Grignard, a leading expert on Islamist terrorist groups in Belgium’s police force, one of the critical elements of a successful counterterrorism strategy to address Islamic extremism is “the empathy one has to entertain with the subject at hand…This empathy has to start with real knowledge of the ‘other’, first empirically, then scientifically, and has to be build upon the units’ contacts in the field.” (Sources: U.S. Department of State 2015, Egmont, Council of Europe)
Belgium believes that the fight against terrorism must not be allowed to infringe human rights, fundamental freedoms or international humanitarian law.
In this vein, Belgium has historically pressured the European Union to search for ‘root causes’ of terrorism, and advocates on the international stage for the fundamental rights of suspected terrorists. Belgium’s Ministry of Foreign Affairs website provides an informational section on “terrorism and human rights.” According to the site, “Belgium believes that the fight against terrorism must not be allowed to infringe human rights, fundamental freedoms or international humanitarian law.” The country “condemns the use of secret prisons” to interrogate suspected terrorists, and asserts that “the principle of the right to a fair trial must be respected, regardless of the accusations levelled against the defendant.” (Sources: Egmont, Belgium’s Ministry of Foreign Affairs)
Today, Belgium works to address the underlying concerns stemming from a relatively high percentage of foreign terrorist fighters to Iraq and Syria and suspected terrorists in the country. Belgium is also working to address the concerns of prison radicalization, and has accordingly increased funding for counter-extremism counseling within the prison system. The government has worked to train imams that work in prisons to identify signs of radicalization among prisoners as well as potential terrorist recruiters that may be playing an influential role in radicalizing other inmates.

Intelligence and Security Infrastructure
In the 1980s, the Belgian government established a branch devoted to countering Islamic extremism within its Anti-Terrorist Unit of the Gendarmerie. In 2001, the Gendarmerie merged with Belgium’s general police force. (Sources: Egmont, Encyclopedia of Law Enforcement)
Today, Belgium’s Criminal Investigation Department acts as its civilian intelligence service. The intelligence unit cooperates with Belgium’s local and federal police forces to prevent terrorism and crime. Belgium’s Threat Analysis Co-ordination Body (OCAM) analyzes the threat of terrorism and extremism on the basis of intelligence gathered from Belgium’s various counterterrorism bodies. Belgium’s overarching counterterrorism program is controlled by its Minister of Interior. Belgium’s Prime Minister oversees the counterterrorism program, and chairs the Ministerial Committee on Intelligence and Security. To coordinate between the judicial and executive components of Belgium’s counterterrorism program, a new ‘nerve centre’ was created in 2006: OCAM (Organe de Coordination et d’Analyse de la Menace). OCAM is under joint authority of the Ministers of Justice and the Interior. (Sources: Council of Europe, Egmont)
Belgium’s intelligence infrastructure has recently come under criticism for its failure to quash jihadist activity and illegal weapons trading within its borders. One factor blamed for compromising intelligence is the country’s language divide, with some Belgian intelligence officers operating in Flemish and others in French. This occasionally leads to gaps in intelligence, even for officers operating within the same neighborhood, like Molenbeek. Other issues facing the intelligence service include a lack of resources and lack of “cultural and political” prioritization of the intelligence service. Belgian’s intelligence community is also strained to meet the high surveillance demands. Belgium’s intelligence community is reportedly responsible for monitoring more than 200 jihadists in Syria. (Sources: France24, Le Soir, U.S. Department of State 2015)
Belgium has increasingly bolstered its counterterrorism legislation in order to meet mounting terrorism concerns. In 2015, Belgium announced efforts to crack down on suspected foreign fighters and terrorists, including by strengthening legislation that would prohibit Belgians from traveling abroad to join militant groups, and stripping convicted terrorists of their Belgian citizenship if they have dual citizenship. In early 2017, Belgium passed legislation authorizing the government to deport legal residents on suspicion of engaging in terrorist activities. In accordance with United Nations resolutions and EU law, Belgium has criminalized terrorism, including participation in acts of terrorist groups and financing terrorism. Suspected terrorists in Belgium have historically been treated with the same procedural rights (including the right to a fair trial) as ordinary criminals. However, the Belgian judiciary and the Belgian government are independent of one another which can lead to ambiguous classifications of what and who are considered to be agents of terrorism. Despite the Belgian government criminalizing terrorism, in March 2019, the Belgian Court of Appeals stated that the terrorism label does not apply to forces engaged in an armed conflict. When Belgian federal prosecutors were seeking to try around 30 suspected members of the PKK who allegedly recruited and trained young Kurds in Belgium and elsewhere in Europe, the Brussels appeal court ruled that “insufficient elements were provided to conclude that the PKK is guilty of terrorist offenses.” The Brussels Appeals Court ruled that the counterterrorism laws cannot be imposed on the suspects since they are not waging a war on Belgium, but Turkey.

In December 2003, Belgium enacted the Terrorist Offences Act, which translated the EU Framework Decision on terrorism from June 2002 into Belgian law. The Act defines terrorism as a set of offences that “by its nature or context may cause serious harm to a country or an international organization,” including those “committed intentionally with the aim of seriously intimidating a population or unduly forcing public authorities or an international organisation to take or refrain from taking certain action or seriously destabilising or destroying the fundamental political, constitutional, economic or social structures of a country or an international organisation.” In defining terrorist groups, the Act qualified that an “organization whose real purpose is solely of a political, trade union or philanthropic, philosophical or religious nature, or which solely pursues any other legitimate aim, cannot, as such, be considered a terrorist group.” (Source: Council of Europe)
Under the 2003 Terrorist Offences Act, investigations of acts on the list of terrorist offenses are authorized to use telephone tapping, proactive investigations, infiltration measures, observation measures involving the use of technical devices to spy into people’s homes, questioning of witnesses under conditions of complete anonymity, secret surveillance, and special protection measures granted to a threatened witness by the Witness Protection Board.

Prisoner-Exchange Treaty with Iran
On July 21, 2022, the Belgian parliament ratified a treaty that would allow Iranian nationals convicted of terrorism in Belgium to be extradited to Iran to serve their sentence. Belgian nationals convicted in Iran would also be extradited to Belgium to complete their sentence. Accordingly, each country can issue amnesty for the captives once they are extradited. The treaty originated in late February when the Iranian authorities detained Olivier Vandecasteele, a Belgian aid worker, on charges of espionage. Although Vandecasteele’s arrest was not made public, on March 11, Belgium signed the prisoner-exchange treaty with Iran that was then ratified in July 2022. The treaty also allows each party to grant amnesty when their nationals are extradited back to their home country. According to critics, Iran pushed for the treaty to secure the return of Assadollah Assadi, an Iranian diplomat who was convicted to 20 years in prison for orchestrating a plot to bomb a 2018 meeting of Iranian opposition leaders in France. If Assadi is allowed to return to Iran, critics claim he will likely be released rather than serving out the remainder of his sentence. (Sources: Middle Eastern Monitor, New York Times)
Policy on Radicalization and Foreign Fighters
According to a Belgian government official, returning foreign fighters are treated to “particular attention” from the government. Former Interior Minister Joelle Milquet explained that there is usually an arrest or follow-up on the suspect. If there is no open criminal record, the suspected foreign fighter is often followed by the local intelligence service or police. (Sources: Le Soir, Guardian)
In 2013, the government started radicalization-prevention programs to address the rising trend of foreign fighters. The efficacy of these programs is dubious. According to an adviser to the Belgian government on radicalization, “The preventive proposals were not well thought through.” In 2016, the government opened its first deradicalization center, modeled on a Canadian center for countering radicalization. The center features a 24-hour hotline for parents and loved ones to call for help, and a staff of 15 criminologists, psychologists, and other specialists. In a June 2018 assessment, a U.N. special rapporteur on human rights and terrorism chastised Belgium for not instituting any deradicalization or disengagement programs in its prison system. She called on Belgium to implement deradicalization programs and make strides in protecting the children of imprisoned extremists. (Sources: Wall Street Journal, Montreal Gazette, United Nations)
The effects of failed policies aimed at Belgium’s foreign fighters are already evident. Among Belgium’s returning foreign fighters from ISIS were the November 13, 2015, mastermind Abdelhamid Abaaoud and at least one of the assailants, Ismaël Omar Mostefaï. Mehdi Nemmouche—the French national who carried out the May 2014 attack on the Jewish Museum of Brussels—had also returned to Europe after fighting with ISIS. (Sources: Telegraph, Telegraph)
According to the October 2015 U.N. report, Belgium needs to develop a national vision to address the issue of foreign fighters at the federal, regional, community and local levels, “[o]therwise, the threat to the country is significant.” (Source: Express.be)
In December 2019, it was reported by Belgium’s federal prosecutor’s office that the number of new cases of terrorist activity in Belgium fell to 90, in comparison to 155 in 2018. The figure has not been that low since ISIS came onto the scene in 2013. According to federal prosecutor Frederic Van Leeuw, the terrorist threat comes not from structured terrorism, but rather from lone wolf actors seeking to commit attacks in Belgium and elsewhere.

Combating the Illegal Weapons Trade
Prior to 2006, Belgium had non-restrictive gun-ownership laws and was largely considered a hub for weapons dealers because of a flood of weapons from the war in the former Yugoslavia and also lax gun laws stemming from state-owned FN Herstal sidearm manufacturer, which supplied weapons to a number of foreign armies. In 2006, the government passed legislation criminalizing ownership of automatic weapons and enacting tougher procedures to purchase guns. Nonetheless, media reported in November 2015 that criminals could obtain military-grade weapons within one hour in Molenbeek. Analysts reported that they could not accurately estimate how many illegal guns were on the streets in Molenbeek, and Belgium came under pressure for its failure to quash the illicit weapons market there. Assailants who are believed to have acquired weaponry in Molenbeek include August 2015 train suspect Ayoub El Khazzani, January 2015 kosher supermarket gunman Amedy Coulibaly, and May 2014 Jewish Museum gunman Mehdi Nemmouche.

Role in International Counter-Extremism Policy
Before the surge of Belgian-tied attacks in Europe, the country historically approached counterterrorism measures with caution. Belgium has, however, taken on a more proactive role in the counterterrorism space in recent years. After the thwarted August 2015 attack on a high speed train from Amsterdam to Paris, Belgian Prime Minister Charles Michel called for a review of EU policy on security for international trains, saying that Europe must consider reinstating identity and luggage inspections. Belgium has long played a key role in European counterterrorism efforts. After the November 2015 ISIS attacks on Paris, Brussels was slated to host an emergency meeting of EU interior ministers to deal with longstanding concerns about illegal weapons trafficking.

At the time of the September 11, 2001, attacks, Belgium held the rotating, six-month EU presidency. Ten days after the attacks, Belgium convened a European Council and adopted a Plan of Action to counter terrorism. The plan outlined five EU goals to combat terrorism: (1) strengthen police and judicial cooperation, (2) develop international legal instruments, (3) combat the financing of terrorism, (4) strengthen air security, and (5) coordinate the European Union’s global action.

In December 2005, the European Union adopted a counterterrorism strategy based on four pillars: prevention, protection, prosecution, and response. Belgium successfully petitioned the European Union to address possible “root causes” of terrorism under its “prevention” counterterrorism strategy. In 2006, the European Union decided to forsake the use of the word “root causes” in favor of terms like “underlying conditions” or “conditions conducive to the spread of terrorism.” (Source: Egmont)
Belgium abides by the U.N. and EU counterterrorism sanctions lists, but has advocated for clarified “measures enabling people’s names to be included in or deleted from the lists of suspects.” According to Belgium’s Ministry of Foreign Affairs, the “aim of such clarification is to enable suspected persons to defend themselves and appeal any decisions made against them.” This language was removed from the Belgium’s Ministry of Foreign Affairs website following the wave of European terrorist attacks in 2015 and 2016.

However, designations enacted by the Belgian government are not always observed by the Belgian Court of Cassation—which represents the opinion of the judiciary and is an independent body from the executive branch. On January 30, 2020, the Belgian Court of Cassation confirmed a ruling by the Brussels Court of Appeals that the Kurdish Worker’s Party (PKK) should not be classified as a terrorist organization. Although the Belgian government considers the PKK to be a terrorist organization, the January 2020 ruling claimed that EU anti-terrorism legislation cannot be applied towards the PKK as it is involved in a non-international armed conflict or civil war and is thus allowed to use legitimate military force. The PKK is an internationally designated terrorist organization that has been in conflict with the Turkish government for decades. Although it is uncertain if the ruling will create diplomatic altercations with Turkey, the Belgian government depends on stable relations with Ankara to track Belgian nationals who joined ISIS in Syria and continue to remain in the region.

Foreign Military Engagements
Belgium contributes soldiers and materiel to various U.N.-, EU- and coalition-led operations. It is engaged in the international fight against ISIS and, under EU missions, has deployed soldiers to Mali and the Democratic Republic of Congo. For years, Belgium participated in the International Security Assistance Force (ISAF) mission in Afghanistan. In mid-December 2014, Belgium completed an eight-year UN peacekeeping mission in Lebanon.

Belgian Forces against ISIS: Opération Desert Falcon
Belgium has contributed at least 350 soldiers, pilots and technicians, and a fleet of six F-16s to the international fight against ISIS. The government has also contributed members of its Special Forces to help train, support, and advise Iraqi security forces. According to the Belgian Air Force, Operation Desert Falcon was completed on December 26, 2017, after 18 months. (Sources: La Defense, New York Times, U.S. State Department, Aviation 24)
Belgian Forces in Afghanistan
Belgium contributed to the ISAF mission in Afghanistan. In 2012, Belgium reduced its military participation in Kabul and transferred the bulk of its authority to Hungary. After 2012, Belgian soldiers transitioned to a logistical and advisory role in Afghanistan. Belgium’s most recent count put 20 Belgian soldiers in Kabul. As of 2020, Belgium maintains over 100 soldiers in Afghanistan to provide intelligence tasks in Kabul as well as training and security zone support near the Masar-E-Sharif base. (Source: La Defense)
Belgian Forces in Lebanon
In December 2014, Belgian forces ended an eight year peacekeeping mission for the United Nations Interim Forces in Lebanon (UNIFIL). Almost 5,500 Belgian soldiers served over the years to clear thousands of mines and other explosives along Lebanon’s border with Israel. (Sources: La Defense, UNIFIL)

Belgian Forces in Mali
Belgium has about 80 soldiers stationed in Mali as part of the European Union Training Mission (EUTM). Although Belgium is set to reduce the number of soldiers stationed in Mali in early 2016, the country will continue to provide a smaller group soldiers to the U.N. mission in Mali. In 2020, Belgium continues to support EUTM with 15 soldiers who provide training to the Malian armed forces. As of June 2020, Belgium continues to participate in the U.N. Multidimensional Integrated Stabilization Mission in Mali (MINUSMA). Around five soldiers are headquartered at intelligence services in Bamako, over a dozen intelligence specialists are stationed in Gao, and around 55 soldiers are part of a platoon within a German unit.

Belgians are highly concerned with threats from terrorism, according to 2016 public opinion surveys. A Gallup poll from 2016 found that 88 percent of Belgians surveyed considered acts of terrorism by residents “a serious problem” and 92 percent found that acts of terrorism from non-residents constituted a “serious problem. Research commissioned by the European Parliament found that 50 percent of Belgians believed that the risk of a terrorist attack was elevated. The surveys were conducted in April of 2016, one month before ISIS launched its March 2016 Brussels attacks. (Sources: Gallup, EPRS)
In March 2017, one year after the Brussels attacks, Belgians continued to perceive the terrorism threat as very high. Seventy-seven percent of Belgian respondents considered the threat from terrorism to be strong or very strong, compared to 69 percent of respondents who felt similarly in March 2015. According to the survey of 2,898 respondents from around the country, the fear was especially pronounced in Brussels, where roughly 25 percent of respondents characterized the terrorism threat as “very high” in 2017.
