UK Counterterror Police Probe Arson at Former London Synagogue Amid Wave of Antisemitic Attacks

This incident follows a pattern of targeted violence, including the torching of four ambulances owned by a Jewish charity in March, a synagogue firebombing, and other attempted arsons at Jewish sites. Last week, two Jewish men were stabbed in an act police described as terrorism, contributing to the ongoing wave.

The Community Security Trust charity reported a sharp increase in antisemitic incidents across the U.K., recording 3,700 cases in 2025 compared to 1,662 in 2022. The surge began after the October 7, 2023, attack by Hamas-led militants on southern Israel and the ensuing Gaza war, but recent attacks have intensified since the February 28 start of the Iran war.

Keir Starmer convened a meeting with community leaders to confront the crisis, describing the attacks as a pattern of rising antisemitism that has left Jewish communities feeling frightened and angry. He emphasized that these acts target British Jews but represent a broader societal crisis.

Starmer pledged measures to combat antisemitism, including requiring universities to report and address the issue, and withdrawing arts funding from those promoting it. This adjustment accounts for threats from Islamist and extreme right-wing groups, as well as the recent stabbings.

Starmer highlighted that the crisis affects all citizens and vowed intolerance for any attempts to foment violence or division.

Police are exploring whether foreign states, including Iran, are involved in some incidents, as Starmer noted one line of inquiry focuses on this possibility. A pro-Iran group, Harakat Ashab al-Yamin al-Islamia, claimed responsibility for several attacks on places of worship, businesses, and financial institutions linked to Jewish or Israeli interests across Europe.

The group has admitted to similar actions in recent months. Starmer issued a direct message that such interference would not be tolerated. Investigations continue into connections between the recent U.K. attacks and this group, with counterterror units leading the probe into the synagogue arson.

No arrests have been reported in the latest incident, but forensic teams are examining the scene. The wave of violence has prompted outrage and calls for stronger protections. Community leaders expressed concerns about safety, while police have increased patrols in affected areas.

The incidents underscore broader tensions tied to international conflicts, with authorities monitoring for further escalations.
