Attacks on the Jewish community are "gathering momentum", the Chief Rabbi says, after another arson attack was reported at a north-west London synagogue.
The warning comes after Kenton United Synagogue in Harrow was attacked overnight, the latest in a series of arson attacks on Jewish properties this month.
Counter-terrorism police are investigating whether they are linked to a group with possible ties to Iran, with officers warning those involved will face serious prosecution under national security laws.
Chief Rabbi Sir Ephraim Mirvis described the latest attack as "cowardly" while Prime Minister Sir Keir Starmer said he was appalled and that "visible policing" would be increased.
At a press briefing outside Kenton United Synagogue on Sunday, deputy assistant commissioner Vicki Evans said the incidents were similar in nature and had been claimed online by a group called Ashab al‑Yamin, which had also claimed attacks on Jewish targets across Europe.
