British police have arrested three more men in connection with an arson attack on Jewish community ambulances in north London.
The ambulances were set on fire on March 23 in what British Prime Minister Keir Starmer described as a "deeply shocking anti-Semitic 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.
