London - British counter-terror police are investigating an arson attack at a former synagogue in east London early Tuesday, the Metropolitan Police confirmed. Surveillance video shows the fire was set intentionally; no injuries or arrests have been made.

Prime Minister Keir Starmer, meeting with community leaders and police chiefs Tuesday, called the surge in antisemitic attacks a "crisis." He stated that one line of inquiry is whether a foreign state is behind the attacks, warning of "consequences" if Iran is implicated.
A group linked to Iran, Harakat Ashab al-Yamin al-Islamia, has claimed responsibility for recent antisemitic attacks in Britain and other European countries. The group previously told CBS News it would target US and Israeli interests globally.
