(New York, N.Y.) — The Counter Extremism Project (CEP) reports on the methods used by extremists and terrorist groups on the Internet to spread propaganda and incite violence. Last week and the week before, the pro-ISIS online community noted the October 2 Yom Kippur attack on a synagogue in Manchester, UK. On October 8, a pro-ISIS Telegram channel pointed out that the attacker had pledged his allegiance to the terrorist organization, repeating information that the British police had made public. The October 9 ISIS newsletter did not mention the attack.
On October 7, CEP researchers located 20 accounts on TikTok that posted pro-ISIS content, including a video glorifying vehicular suicide attackers that received over 60,000 views. The pro-ISIS tech group Electronic Horizons Foundation (EHF) posted advice for using the Tor Browser.
On Instagram, CEP researchers located an account with over 31,000 followers that posted a large quantity of antisemitic content, including a video accusing Israel of assassinating the right-wing activist Charlie Kirk, which received over 3.1 million views. In the week after CEP reported the account, it had received approximately 4,000 new followers and posted antisemitic AI-generated videos using the Sora AI app.
On October 3, a Telegram channel affiliated with the white supremacist Active Club movement in Sweden posted a video that showed their members using a rifle and a shotgun at a firing range. The video was posted shortly after alleged members of a German chapter of the movement were reportedly arrested for posing with firearms in social media posts. Elsewhere on Telegram, white supremacist and neo-Nazi channels celebrated the second anniversary of the October 7 attacks, and several other channels lauded the FBI cutting ties with the Anti-Defamation League and the Southern Poverty Law Center. Finally, CEP researchers reported a YouTube account connected to a member of the antisemitic provocateur group the Goyim Defense League that had posted videos.
Pro-ISIS Online Community Notes Manchester Synagogue Attack; No Mention of Attack in October 9 ISIS Newsletter
Members of the pro-ISIS online community noted the October 2 Yom Kippur attack on a Manchester area synagogue by an individual who used a knife and a vehicle as a weapon, leading to the deaths of two people and three injuries. On October 8, British police confirmed that the attacker, Jihad Al-Shamie, had called an emergency phone line to claim credit for the attack and pledge his allegiance to ISIS.
Pro-ISIS users on RocketChat noted the attack on October 2 and 3, with one user advising others to wait for an official ISIS acknowledgement or claim of responsibility before celebrating the perpetrator. A pro-ISIS Telegram channel posted available news photos of the attack on October 2. The same channel noted on October 8 that the attacker had “dedicated” the attack to ISIS.
Issue 516 of ISIS’s weekly al-Naba newsletter, released on October 9, did not include a mention of the attack. An earlier editorial in the September 18 al-Naba release called for attacks on Jews to avenge those killed by Israel in Gaza. The article noted that this was especially important in Europe, specifically noting the United Kingdom, Belgium, and France.

One account, which had almost 3,000 followers, posted a video glorifying ISIS vehicular suicide attackers and contained footage from official ISIS propaganda videos. The video, which was uploaded to TikTok in July, had over 61,000 views when it was found on October 7.

Telegram Account Linked to Active Clubs in Sweden Posts Video of Members Using Firearms
On October 3, a Telegram channel for “Gym XIV,” part of the Swedish Active Club network, posted a video of the group’s members using firearms, working out, and affixing an Active Club-affiliated brand sticker to a pole. The video, which has a watermark for an Active Club-affiliated clothing brand, shows Swedish members using a scoped AR-15-style rifle and a shotgun at a firing range. Ammunition and a magazine for 5.56mm rounds are displayed, showing that the firearm is not airsoft or a replica. The video had over 4,600 views and 55 shares four days later, and was also posted by the main Active Club Telegram account, as well as an account that promotes the movement’s founder, Robert Rundo.
The video was released two days after police arrested six members of a German Active Club chapter in North Rhine-Westphalia who had posed on social media with firearms and edged weapons. On October 1, the main Active Club Germany Telegram account denied involvement in criminal activity, stating that the use of weapons contradicted Active Club principles, and further clarified that those arrested were allegedly not members of an Active Club chapter.

Extreme Right Telegram Channels Celebrate FBI Cutting Ties with the ADL and SPLC
Multiple white supremacist and neo-Nazi Telegram channels celebrated the FBI’s cutting of ties with the Anti-Defamation League (ADL) and the Southern Poverty Law Center (SPLC). On October 1 and 3, a Telegram channel tied to a website that promotes neo-Nazi accelerationism and is operated by former members of the Atomwaffen Division cheered the decision, hoping that the movement would benefit, specifically accusing the SPLC of assisting “every major movement arrest [in] the past decade.” Telegram channels connected to the neo-Nazi Aryan Freedom Network and a Tennessee Active Club shared posts noting that the FBI would cease working with the SPLC. In contrast, a white supremacist news channel with over 3,600 followers that supports Active Clubs and Patriot Front, claimed that this development would be “a lot cooler if it didn’t seem [like] we were on the verge of attacking Iran for Israel again.”
