The UK's Chief Rabbi, Ephraim Mirvis, has warned that British Jews are facing a "sustained campaign of violence and intimidation" following an attempted arson at a London synagogue, the latest in a series of arson attacks on Jewish-linked premises and an Iranian opposition outlet. The incident occurred on a Saturday night and follows a spate of similar incidents, which have been investigated by counterterror police. The Metropolitan Police has sent extra uniformed and plainclothes officers to investigate these incidents. Prime Minister Keir Starmer has pledged that those responsible will be brought to justice. The UK has accused Iran of using criminal proxies to conduct attacks on European soil against opposition media outlets and the Jewish community.
