London's police said they are investigating an "arson attack" as an antisemitic hate crime after volunteer ambulances run by a Jewish organization were set on fire on Monday.
The London Fire Brigade said it was alerted to vehicles on fire at Highfield Court in Golders Green at 1:40 am.
Firefighters called to the scene found that multiple cylinders on the vehicles had exploded, breaking windows in an adjacent block.
London's Metropolitan Police said the burnt vehicles were four Hatzalah ambulances belonging to the Jewish Community Ambulance service, AFP reported.
"Officers remain on scene and the arson attack is being treated as an antisemitic hate crime," police said in a statement.
No injuries have been reported and all the fires have been put out, police added.
"We know this incident will cause a great deal of community concern and officers remain on scene to carry out urgent enquiries," superintendent Sarah Jackson said.
"We are in the process of examining CCTV and are aware of online footage. We believe we are looking for three suspects at this early stage," she said, adding that no arrest has been made.
Nearby houses were evacuated as a precaution and road closures remained in place.
London Fire Brigade said the cause of the fire is under investigation.
