British police are formally investigating whether recent arson attacks on Jewish sites in London were carried out by Iranian proxies, with the attacks claimed by a group called Harakat Ashab al-Yamin al-Islamia that Israeli intelligence links to Iran. No injuries have occurred so far, but the UK's chief rabbi said British Jews face an escalating campaign of violence and intimidation. The group has also claimed responsibility for synagogue attacks in Belgium and the Netherlands, suggesting a coordinated European operation tied to Iranian regime tactics.
