British police have launched an investigation into an apparent arson attack on ambulances belonging to a Jewish emergency service in London, treating it as a hate crime.

An arson attack on four ambulances belonging to a Jewish community ambulance service in north London is being treated as an "antisemitic hate crime", the Metropolitan Police says.

Jewish community leaders condemned the attack, with the chief rabbi Ephraim Mirvis saying the targeting of the volunteer service was “particularly sickening”.
