According to former ISIS hostage Nicolas Hénin, Nemmouche would regularly beat and torture prisoners.

Nemmouche returned from Syria to France in March 2014 and traveled to Brussels several weeks later. On May 24, 2014, Nemmouche stormed into the Jewish Museum of Belgium in Brussels, killing four people.“Mehdi Nemmouche: ce que l’on sait de son parcours,” Le Monde (Paris), August 9, 2014, http://www.lemonde.fr/societe/article/2014/09/08/mehdi-nemmouche-ce-que-l-on-sait-de-son-parcours_4483458_3224.html. Nemmouche immediately fled the scene and later boarded a bus from Amsterdam heading to France’s southern port city of Marseille. On May 30, 2014, French authorities conducting customs inspections found and detained Nemmouche at the Saint-Charles transit station in Marseille. Authorities confiscated a video recording of Nemmouche claiming responsibility for the Jewish Museum attack. Authorities also seized the two guns used in the museum attack and a white sheet decorated with ISIS’s symbol.“Mehdi Nemmouche, Brussels Jewish Museum shooting suspect, arrested,” CBC News, June 1, 2014, http://www.cbc.ca/news/world/mehdi-nemmouche-brussels-jewish-museum-shooting-suspect-arrested-1.2661011;

On July 30, 2014, Nemmouche was charged with murder in a terrorist context by Belgian courts.Frances Robinson, “French Suspect in Brussels Jewish Museum Killings Charged,” Wall Street Journal, July 30, 2014, https://www.wsj.com/articles/french-suspect-in-brussels-jewish-museum-killings-charged-1406725425. On November 3, 2016, Belgium prosecutors decided that Nemmouche would be extradited to France once Belgium “no longer needs him” to face additional charges there.“Suspect in Brussels Jewish museum shooting faces extradition to France,” France24, November 3, 2016, http://www.france24.com/en/20161103-belgium-extradition-france-brussels-jewish-museum-shooting-nemmouche. French authorities are investigating Nemmouche’s participation in the ISIS kidnapping of the four French journalists held hostage in Syria in 2014.“Suspect in Brussels Jewish museum shooting faces extradition to France,” France24, November 3, 2016, http://www.france24.com/en/20161103-belgium-extradition-france-brussels-jewish-museum-shooting-nemmouche.

Nemmouche went on trial in Brussels on January 10, 2019.“Brussels Nemmouche trial: Suspect claims he was ‘tricked,’” BBC News, March 5, 2019, https://www.bbc.com/news/world-europe-47454870. During the trial, Hénin testified that he had no doubt Nemmouche was one of his guards and described Nemmouche as “sadistic, playful and narcissistic.”“Brussels Jewish Museum murders: Mehdi Nemmouche guilty,” BBC News, March 7, 2019, https://www.bbc.com/news/world-europe-47490332. Nemmouche’s attorney protested that his client was on trial only for the museum shooting. In regard to the museum attack, Nemmouche’s attorney alleged that Iranian or Lebanese intelligence had recruited Nemmouche to join ISIS and that he was acting in his capacity as a double agent while he was guarding the French journalists. Nemmouche’s lawyer argued further that the Brussels attack was actually a “targeted execution of Mossad agents” carried out by an unknown person. The court found no links to the Mossad, Israel’s foreign intelligence agency.“Brussels Jewish Museum murders: Mehdi Nemmouche guilty,” BBC News, March 7, 2019, https://www.bbc.com/news/world-europe-47490332.

On March 7, 2019, a Belgian court convicted Nemmouche for the murder of four people during the museum attack. The court also convicted Nacer Bendrer on a murder charge for helping Nemmouche plan the attack and providing the weapons. Nemmouche received a life sentence on March 12, 2019. Bendrer received a sentence of 15 years in prison. Nemmouche may also return to France to face kidnapping charges in regard to the four French journalists in Syria.“Brussels Jewish Museum murders: Mehdi Nemmouche guilty,” BBC News, March 7, 2019, https://www.bbc.com/news/world-europe-47490332; “Brussels Jewish Museum murders: Mehdi Nemmouche jailed for life,” BBC News, March 12, 2019, https://www.bbc.com/news/world-europe-47533533.
