British police said on Wednesday they had arrested three more men in connection with an ​arson attack on Jewish community ambulances in north ‌London last month.

The ambulances were set on fire on March 23 in what British Prime Minister Keir Starmer described ​as a “deeply shocking antisemitic arson attack”.

The SITE Intelligence ​website has said an Iran-aligned multinational militant collective ⁠called Islamic Movement of the People of ​the Right Hand had claimed responsibility for the incident ​near a synagogue in the Golders Green area of London.

Counter-terrorism officers are heading the investigation, but as yet the incident ​is not being treated as terrorism.

The Metropolitan ​Police said the three men, aged 20, 19 and 17, had been arrested at ‌separate ⁠addresses in east London on suspicion of conspiracy to commit arson with intent to endanger life.

Two were British nationals, while the third was a ​dual British-Pakistani national. ​Last week, ⁠detectives detained two British nationals aged in their 40s and later released both ​on police bail.

“We know concern among the ​Jewish ⁠community remains high, but I hope these arrests show that we are doing everything we can to ⁠bring ​those responsible to justice,” said ​Commander Helen Flanagan, Head of Counter Terrorism Policing London.
