British police have arrested two men over an arson attack that destroyed four ambulances from a Jewish charity. They're treating the fire as an antisemitic hate crime. Police say the two suspects are in custody in London. Commander Helen Flanagan has called the arrests a breakthrough. She says CCTV suggests three people took part in the attack. Police do not call it a terror attack. They're investigating an online claim from a group with possible Iran links. The fire started early on Monday in the Golders Green neighborhood. Oxygen cylinders exploded and nearby windows shattered. MI5 says it has disrupted many Iran-backed plots.

Police in London are investigating a suspected antisemitic hate crime attack after four vehicles belonging to a Jewish ambulance service were set on fire. Though it has not been classified as a terrorist incident, counterterror officers have been put in charge of the investigation. Detectives are working to determine whether a claim of responsibility from a group with alleged links to Iran is authentic. The London Fire Brigade says ambulances belonging to Hatzola Northwest, a volunteer organization that provides emergency medical response, were damaged by the fire early Monday morning. Multiple oxygen cylinders on the vehicles exploded, causing windows to break in an adjacent apartment block. No one was injured.
