Rotterdam: Jihadist Group Claims Attack on Jewish Site

The group calling itself Harakat As’hab al-Yamin al-Islamiyah (translated as The Islamic Movement of the Companions of the Right) has claimed responsibility for an attack against a site in the city of Rotterdam on Friday morning.

Third claimed attack in Europe this week

According to the statement attributed to the group, this would be the third attack it claims to have carried out this week against Jewish institutions or locations in Europe.

The previous claims include:

  • the explosion outside the synagogue in Liège
  • another attack reportedly claimed in Greece earlier in the week

Reports of arson at a synagogue

Initial reports indicate there may have been an arson attack targeting a synagogue in Rotterdam, although authorities have not yet fully confirmed the details.

If confirmed, the incident would increase the likelihood that the video and claims released by the group correspond to real events, suggesting that a coordinated network may be targeting Jewish sites across Europe.

Investigation ongoing

At this stage:

  • Dutch authorities have not publicly confirmed the claim of responsibility
  • investigators are working to verify whether the attack occurred and who carried it out
  • security services are assessing whether multiple incidents across Europe could be linked

Further details are expected as police and intelligence services in several European countries continue their investigations.

About Sentinel

SENTINEL is a European project funded by the European Commission and led by the Security and Crisis Centre (SACC by EJC), the security arm of the European Jewish Congress. It brings together the International Centre for Counter-Terrorism (ICCT), national-level Jewish communities from Austria, Czech Republic, Hungary, Italy, and Spain, the European Union of Jewish Students, with the support of the Italian Carabinieri and the Police Presidium of the Czech Republic.

The project is designed to strengthen the protection of Jewish places of worship across the European Union through a coordinated set of activities over a three-year period.

SENTINEL will harness AI-enhanced open-source intelligence to monitor and assess current, emerging, and future threats. It will also equip Jewish communities with practical tools, including a mobile security application with a panic button and an interactive map built on real-time incident data.

Training and capacity-building are at the core of the project. These include scenario-based security exercises, crisis management seminars, and both in-person and online training sessions for community security trustees. SENTINEL will also organise EU-wide and local conferences to foster collaboration between Jewish communities, public authorities, and law enforcement agencies.

Complementing these efforts, national and local workshops will promote knowledge-sharing and preparedness, alongside pilot training programmes for law enforcement. A dedicated podcast series will help raise awareness by exploring threat assessments and potential responses.

With its wide-reaching and inclusive approach, SENTINEL will directly benefit to Jewish communities across 23 EU Member States, enhancing resilience, strengthening preparedness, and building long-term cooperation with law enforcement to meet today’s evolving security challenges.
