Synagogue desecrated amid rising anti-Semitism

The surrounding wall of the synagogue in Larissa was vandalized by unknown assailants on Friday, illustrating the worrying rise in anti-Semitic acts in the country.

Two graffiti inscriptions were discovered Thursday evening: “Free Palestine” and another insulting Zionism. The graffiti has since been removed and the wall repainted. Local police have opened an investigation against unidentified perpetrators.

This incident is part of a wave of desecrations. The Central Council of Jewish Communities of Greece (KIS) expressed its “deep concern at the rapid and unprecedented rise in acts targeting Jewish sites.” Recently, the Holocaust Memorial in Larissa, the old Jewish cemetery of the University of Thessaloniki, and the Jewish cemetery in Volos have also been vandalized.  The KIS denounces “attacks on tourists, verbal attacks, acts of vandalism, as well as the continued stigmatization of individuals labeled as ‘murderers’ solely because of their nationality or religion.”

These incidents come as Greece is witnessing numerous pro-Palestinian demonstrations organized mainly by the Greek left to denounce the war in Gaza.

The Greek Jewish community, decimated during the Nazi period (86% murdered), today has only 5,500 members according to the KIS.

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.
