Shocking security footage shows a group of masked suspects lighting a fire by a vehicle belonging to Hatzola, a Jewish volunteer emergency medical service, in Golders Green, London. Explosions were heard in the neighborhood, one of London’s largest Jewish communities, and cops said these were likely triggered by gas canisters on board. Shloimie Richman, the chair of Hatzalah Northwest, said four of the group’s six ambulances were “deliberately targeted in an arson attack,” as reported by CNN. A manhunt for the arsonists is underway and Sir Ephraim Mirvis, Britain’s Chief Rabbi, described the attacks as a “particularly sickening assault.”
