A previously unknown Islamist terror group emerged in March 2026 and executed a coordinated campaign of bombings and arson against Jewish schools and synagogues across three European countries, marking what security analysts describe as a dangerous new front in state-sponsored antisemitic violence on the continent.
Story Snapshot
- Harakat Ashab al-Yamin al-Islamiyya, a new terror group, claimed responsibility for attacks on Jewish institutions in Amsterdam, Rotterdam, Liège, and possibly Greece between March 9-14, 2026.
- An explosive device detonated at the Cheider Jewish school in Amsterdam on March 13-14, causing structural damage but no casualties; CCTV captured a suspect planting the bomb.
- Israel’s Diaspora Affairs Ministry assessed the group as Iran-linked, positioning these attacks within the broader Iran-Israel confrontation and rising European antisemitism.
- Despite limited physical damage, the psychological impact on Jewish communities was severe, prompting heightened security and official condemnation from Dutch and Belgian authorities.
A Ghost Group Materializes with Fire and Explosives
Harakat Ashab al-Yamin al-Islamiyya translates to “Islamic Movement of the Companions of the Right,” a name that meant nothing to counterterrorism agencies until the second week of March 2026. The group announced itself not with manifestos but with nighttime attacks: an arson strike on a Rotterdam synagogue, explosives at a Belgian house of worship in Liège, and a bomb blast against the outer wall of Amsterdam’s Cheider Jewish school. Each incident was documented in claim videos featuring a consistent logo, a deliberate branding exercise suggesting coordination rather than spontaneous rage. The targets were unmistakably Jewish, the timing suspiciously tight, and the perpetrators entirely unknown until they chose to reveal themselves.
What distinguishes this campaign from the lone-wolf stabbings or vehicle rammings that have plagued Europe in recent years is the apparent orchestration across borders. The attacks unfolded over five days in three countries, with at least one additional claimed incident in Greece that remains unverified. Dutch and Belgian investigators opened terrorism probes immediately, but the group had already achieved its primary objective: sowing fear in Jewish communities from the North Sea to the Aegean. Amsterdam Mayor Femke Halsema labeled the school bombing a cowardly act of aggression and acknowledged the unacceptable rise in antisemitism her city now confronts daily.
The Iranian Shadow Over European Synagogues
Israel’s Diaspora Affairs Ministry wasted no time connecting the dots, publicly warning that Harakat Ashab al-Yamin al-Islamiyya operates as an Iranian terror proxy. The assessment rests on circumstantial but compelling evidence: the group’s ideological framing mirrors Tehran’s rhetoric against Zionist targets, the timing coincides with escalating Iran-Israel missile exchanges and proxy warfare across the Middle East, and the operational pattern suggests state facilitation rather than grassroots jihad. Iran has a documented history of deploying or enabling attacks on Jewish and Israeli sites in Europe, from disrupted Hezbollah plots in Cyprus to the 2012 Bulgaria bus bombing that killed five Israelis and a Bulgarian driver.
The use of a Sunni-sounding brand name may be deliberate misdirection, offering Tehran plausible deniability while still advancing its strategic goal of pressuring Israel and its diaspora. Western intelligence agencies have long tracked IRGC units and Hezbollah operatives scouting Jewish institutions across Europe, and the post-October 7, 2023 environment has amplified both the threat level and the ideological justification for such operations. Online incitement from pro-Iran channels has intensified calls to strike Zionist entities worldwide, lowering the operational threshold for small cells with minimal training. If the Israeli assessment holds, these attacks represent not random terror but calibrated asymmetric warfare executed through expendable proxies on European soil.
Belgium and the Netherlands: Fertile Ground for Jihadist Operations
The choice of Belgium and the Netherlands as primary theaters was no accident. Belgium has earned an unfortunate reputation as Europe’s jihadist hub, producing more foreign fighters per capita than any other EU nation and serving as the logistical base for the 2015 Paris attacks and the 2016 Brussels Airport and metro bombings that killed 32 people. The Molenbeek district of Brussels remains synonymous with radicalization, and the 2014 Brussels Jewish Museum shooting demonstrated that Jewish institutions are viewed as legitimate and vulnerable targets within these networks. The Netherlands, while less notorious, has its own clusters of radicalized cells in Amsterdam and Rotterdam, cities with visible Jewish communities and the kind of soft targets that require fewer resources to strike.
Night operations at under-guarded locations allowed the attackers to maximize symbolic impact while minimizing the risk of interception. European security services have struggled for years to balance resource constraints with the sheer number of sites requiring protection, and Jewish schools and synagogues often rely on part-time security or municipal police patrols that thin out after dark. The attackers exploited this vulnerability with precision, planting explosives or igniting fires when buildings were empty, ensuring no mass casualties that might trigger an overwhelming law enforcement response but still delivering a message of intimidation that resonates far beyond the immediate blast radius.
The Psychological Weapon: Fear Without Fatalities
Zero deaths across multiple attacks might seem like operational failure, but for a terror campaign aimed at psychological disruption rather than body count, it represents calculated success. Jewish parents in Amsterdam now drop their children at school wondering if tonight will bring another bomb. Synagogue congregants in Rotterdam and Liège arrive for Shabbat services scanning rooftops and parked cars, their religious practice now inseparable from security paranoia. This is the intended outcome: to make Jewish life in Europe feel perpetually unsafe, to impose a tax of fear on communal gatherings, and to signal that no Jewish institution is beyond reach.
The broader Jewish diaspora is watching and drawing conclusions. Migration inquiries to Israel tick upward after each incident, and European governments face uncomfortable questions about their ability to protect minority communities in an era of resurgent antisemitism. The post-October 7 spike in anti-Jewish incidents across Europe already strained communal resources and public patience; this coordinated campaign by a new, state-linked actor escalates the crisis to a different plane. Dutch and Belgian officials vowed solidarity and promised enhanced security, but the uncomfortable truth remains: soft targets are nearly impossible to harden completely, and a motivated adversary with modest resources can keep striking.
The Historical Echo: From ISIS to Iranian Proxies
Europe’s counterterrorism apparatus was built to combat the ISIS wave of 2015-2017, when suicide bombers and vehicle attacks targeted public spaces, concerts, and transportation hubs in Paris, Brussels, Berlin, Nice, and Manchester. Those attacks prioritized mass casualties and media spectacle, aiming to terrorize entire societies and provoke civilizational confrontation. The current threat is more focused and arguably more insidious: Jewish-specific targeting that recalls earlier incidents like the 2012 Toulouse school shooting, where Mohammed Merah murdered three children and a rabbi, or the 2015 Hyper Cacher kosher supermarket siege in Paris, where four Jews were killed during the Charlie Hebdo aftermath.
What distinguishes Harakat Ashab al-Yamin al-Islamiyya from those lone actors is the evidence of coordination and potential state backing. Lone wolves are frightening but containable; state-sponsored cells with cross-border logistics, shared branding, and systematic target selection represent a persistent, renewable threat. If Iran has indeed activated a new proxy brand for European operations, it signals a strategic shift from sporadic disrupted plots to sustained low-intensity campaigns designed to pressure Israel indirectly by destabilizing its diaspora. European security services now face the dual challenge of tracking local operatives and interdicting the foreign facilitation networks that enable them.

The absence of arrests weeks after the attacks suggests either sophisticated operational security or a lack of actionable intelligence, neither of which bodes well for prevention of follow-on strikes. CCTV footage from Amsterdam captured a suspect planting the school explosive, but identification and apprehension have not been publicly announced. Dutch and Belgian investigators are coordinating across borders and likely liaising with Israeli and broader European intelligence partners, yet the group’s ability to execute multiple attacks and vanish points to careful planning and probable external support. The claimed attack in Greece, though unverified, hints at even wider ambitions or at least the desire to project a multinational reach that amplifies the psychological impact.
