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 Crown Prosecution Service said the three men – aged 20, 19 and 17 – have been charged with arson with intent to damage property and being reckless as to whether life would be endangered. Two are British nationals, while the third is a dual British-Pakistani citizen.
The three men were expected to appear at Westminster Magistrates’ Court on Saturday.
