Austria: Inert Hand Grenade Found Near Synagogues in Vienna Triggers Major Police Operation

A non-functional hand grenade discovered Sunday morning near two synagogues in Vienna’s Leopoldstadt district led to a large-scale police response. The grenade, an old Soviet F1 model from the 1970s, was wrapped in a white cloth and left in a building entrance on Tempelgasse, directly across from the places of worship.

The object was spotted by a staff member of one of the synagogues, who immediately notified authorities. Police cordoned off the area and deployed a bomb disposal unit as a precaution. Specialists safely removed the device and later confirmed it contained no explosives and was not capable of detonation.

Investigators have found no evidence so far indicating a direct link between the grenade and the synagogues, and no accompanying threat letter or message has been discovered. Nevertheless, due to the sensitive location, the domestic intelligence service was brought in to assess the situation.

The origin and motive behind the placement of the defunct explosive remain unclear, and the incident is under ongoing investigation.

Tempelgasse holds historical significance as the former site of Vienna’s largest synagogue, the Leopoldstädter Tempel, destroyed during the Nazi era. Today, the area is home to two active synagogues and a support center for Holocaust survivors and their descendants.

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.
