LONDON (AP) — Four ambulances belonging to a Jewish charity were set on fire early Monday in London in what British police are investigating as an antisemitic hate crime. Detectives are working to determine whether a claim of responsibility from a group with alleged links to Iran is authentic.

Though it has not been classified as a terrorist incident, counterterror officers have been put in charge of the investigation. No one was injured in the nighttime attack, which shattered windows in nearby homes and left the vehicles charred shells.
