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 the 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.
