London's Metropolitan Police announced it has opened a formal investigation after receiving reports that four ambulances belonging to the Jewish rescue organization Hatzolah NorthWest were set on fire in the Golders Green neighborhood of Britain's capital, in what appears to be an antisemitic incident. The ambulances were parked outside a synagogue in a neighborhood with a large Jewish population. According to security camera footage from the scene, seen by CNN, three masked individuals arrived at the vehicles and set them on fire.
