A new extremist group, believed to have ties with the Iranian government, has surfaced in Europe, claiming responsibility for a series of attacks targeting Jewish sites. The group, known as Harakat Ashab al-Yamin al-Islamiyya, or The Islamic Movement of the Companions of the Right, has been linked to four separate incidents across the continent.
The first reported attack occurred at a synagogue in Liège, Belgium, where an explosive device was detonated on Monday. This was followed by an arson attack on a synagogue in Rotterdam on Friday night. The violence continued with an explosion at a Jewish school in Amsterdam the next evening.
While details remain sparse, sources have suggested that the group may also be responsible for an additional attack on a Jewish site in Greece on Wednesday, though no specific information on the target or method has been disclosed.
In Liège, the synagogue on rue Leon Fredericq was struck by an explosion at approximately 4 a.m. on March 9, 2026. The previously unknown group, Harakat Ashab al-Yamin al-Islamiyya, has since acknowledged its involvement.
Joe Truzman, a senior research analyst at the Foundation for Defense of Democracies and editor of the FDD’s Long War Journal, shared his insights with Fox News Digital. Initially skeptical, Truzman described the group’s early statements as somewhat “amateurish.” However, as more videos emerged, he noted that the organization might have more depth and complexity than initially perceived.
He said that the war in Iran has likely “compelled the group, for whoever is behind this, to start launching these attacks.” Truzman said he “suspect[s] this organization is being directed” and that there is “an entity behind it.”Â
Truzman says he suspects the Islamic Revolutionary Guard Corps (IRGC) itself, which he says “has been active in Europe” and has “attempted to eliminate or assassinate dissidents.” Though he does not discount them being entity of an Iraqi militia group.

In addition to anticipating further attacks from Ashab al-Yamin, Truzman said that he is concerned that “the dissemination of [terror] videos online may compel other people to commit antisemitic attacks” in Europe. According to Truzman, Ashab al-Yamin’s videos are “starting to gain traction. They’re starting to get the views, and people are seeing it. And maybe the ones that are radicalized already or are going to be radicalized, may be influenced by these videos, and may commit an antisemitic attack or an attack on a Jewish site.”
He said that the attacks “have been mostly unsophisticated, but things may change, and they may start targeting people, too, during the day, when it’s busy.” So far all attacks have come at night.
Israel’s Ministry of Foreign Affairs posted on X that the group was tied to the regime in Tehran. “A jihadi group tied to an Iranian proxy” was responsible for the string of attacks. They noted that “the IRGC continues to sponsor and export terror across the globe.”
Onlookers are increasingly tying the attacks back to the war in Iran. The World Jewish Congress raised alarm bells about Ashab al-Yamin on X, stating that “security analysts believe the group may be part of Iran’s expanding network of proxy actors operating far beyond the Middle East.” The Congress called on governments to “treat this threat with the seriousness it deserves, dismantle the networks behind these attacks, and ensure Jewish communities can live and worship in safety.”
Amichai Chikli, Israel’s Diaspora Affairs Minister, called the attacks “part of a troubling pattern.” He explained that “terror networks linked to the Iranian axis are trying to expand their arena of activity into European cities and Jewish communities.”

The State Department did not respond to questions about whether it had previously been tracking Ashab al-Yamin, or if it planned to issue a warning to Americans traveling abroad to avoid Jewish institutions.
Israel’s National Security Council recently warned its citizens traveling abroad to conceal items that might identify them as Israeli or Jewish and to “avoid visiting sites identified as Jewish or Israeli” following the first of three shootings at Toronto synagogues in early March.
