Several ambulances belonging to Jewish volunteer emergency medical service Hatzola Northwest were set ablaze in Golders Green, London, in a suspected antisemitic arson attack early on Monday morning, surveillance footage shared on social media appears to show.

The footage appears to show several hooded or masked men pouring gasoline on the vehicles before fleeing the scenes.

Four ambulances appear to have been destroyed in the incident.

"At around 01:45hrs on Monday, 23 March police were called by the London Fire Brigade to reports of a fire on Highfield Road, Golders Green," London's Metropolitan Police said, announcing that there are police officers at the scene and an investigation has been opened.

Nearby houses were evacuated, police noted.

"We are in attendance managing a fire," a spokesperson for London's fire service told CNN.

The fire service spokesperson was not able to confirm the cause of the incident at this stage, including whether an explosion had occurred, according to CNN.

Golders Green is home to a notable Jewish community in northwest London.

Police confirmed that there were no casualties in the incident.

"We know this incident will cause a great deal of community concern and officers remain on scene to carry out urgent enquiries. 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," the Met's Superintendent Sarah Jackson said.

"We will be engaging with faith leaders and carrying out additional patrols in the local area as we continue our investigation to provide reassurance and a highly visible presence," she added.

"There have been no arrests yet, and we would urge anyone with information to please contact us as soon as possible - you can do so anonymously if you wish," she said.
