British police arrested two men in London on suspicion of arson with intent to endanger life following an attack on four ambulances belonging to the Jewish charity Hatzola Northwest.
The incident occurred in Golders Green, a London neighborhood with a large Jewish population, where oxygen cylinders in the vehicles exploded, breaking windows in nearby buildings.
Officers are searching two properties in north London and have not classified the attack as a terror act, though they are investigating a claim of responsibility by a group with potential ties to Iran.
Surveillance footage suggests three people were involved, and police have increased security for Jewish institutions ahead of Passover.
