Scotland Yard Investigates Iranian Proxies Behind London Arson Attacks on Synagogues and Jewish Charities

Scotland Yard detectives are investigating whether a series of arson attacks on Jewish sites across London over the past several weeks were directed by Iranian proxies operating in the United Kingdom — part of what British security officials increasingly believe is a coordinated campaign of violence carried out by operatives with ties to Tehran during the ongoing military confrontation between the United States and Iran in the Persian Gulf.

The most significant of the recent incidents occurred on March 23, 2026, when four ambulances belonging to a Jewish emergency volunteer charity were torched in the Golders Green neighborhood of north London, an area with a large Jewish community. Other attacks have targeted a synagogue in the Kenton district of Harrow and a Persian-language media outlet in London that produces journalism critical of the Iranian government. Across the incidents, no fatalities have been reported, though several people sustained minor injuries.

Responsibility for several of the attacks has been claimed by a group calling itself Harakat Ashab al-Yamin al-Islamia — the Islamic Movement of the Companions of the Right. British counterterrorism experts have assessed that this is most likely a flag of convenience, a name adopted to claim attacks without establishing a coherent organizational structure that could be infiltrated or prosecuted. The pattern of targeting and the tradecraft observed in the attacks are, according to unnamed intelligence officials cited in British press reports, consistent with the modus operandi of Iranian-directed criminal proxy networks that have been used in previous operations in Europe.

Several individuals ranging from teenagers to people in their forties have been arrested and charged in connection with the attacks. British prosecutors have not yet publicly alleged direct Iranian state direction of any individual defendant, but investigators are examining phone and financial records for links to Iranian intelligence networks.

Britain has previously accused Iran of using criminal proxies to plan and conduct operations on British and other European soil, including an alleged Iranian-directed plot to assassinate Israeli diplomats and businessmen in the United Kingdom in 2023, and a separate operation disrupted in Germany in 2024. The scale and tempo of attacks since the beginning of the U.S.-Iran military confrontation in April 2026 appear to represent an escalation, as Tehran faces mounting pressure and may be attempting to signal its capacity to strike at perceived adversaries and their allies in third countries.

Britain's Chief Rabbi Sir Ephraim Mirvis described the Jewish community as facing "a campaign of violence" and called on the government to treat the attacks with the same urgency applied to other forms of terrorism. Several senior members of parliament from both the Conservative Party and Labour called for the government to consider proscribing the claiming group and to convene an emergency briefing for senior legislators on the scope of the alleged Iranian proxy threat.

The United Kingdom expelled an Iranian diplomat in 2023 and has coordinated with European partners on a series of sanctions targeting Iranian intelligence officials implicated in assassination and kidnapping plots. Those measures have not visibly deterred the threat. Security officials in France, Germany, and Sweden have each warned in the past 18 months of growing Iranian-directed activity on their soil as well, including surveillance of Iranian dissidents and members of the Jewish community.

The Metropolitan Police confirmed it was treating the recent incidents as hate crimes with a potential terrorism dimension and said it had significantly increased its presence at Jewish community institutions across London following the March ambulance attack.
