British counterterror police are actively investigating a series of arson attacks on Jewish sites in London, with initial evidence pointing towards suspected Iranian proxies. These incidents, including fires at synagogues and Jewish charities, have heightened concerns about a coordinated campaign of violence and intimidation aimed at the community. Authorities are exploring links to a group called Harakat Ashab al-Yamin al-Islamia, which claims responsibility for multiple assaults and has connections to Iran, according to intelligence assessments.

The attacks have been met with strong condemnation from UK officials. Chief Rabbi Ephraim Mirvis described the violence as a growing campaign of hostility against Jews, while Prime Minister Keir Starmer labeled the assaults as 'abhorrent' and assured that perpetrators will be brought to justice. In addition to arson, the group has issued threats against Israel’s embassy, including a threatening video, prompting police to investigate nearby areas and shut down public spaces as a precaution. UK authorities, including MI5, have warned about Iran’s use of criminal networks to carry out such attacks across Europe, with over 20 plots disrupted in the past year.
