(CNN)At least seven people have been killed and 48 injured in a terror attack in central London, with police shooting three suspected assailants dead.
The attack began late Saturday night, when a white van stuck pedestrians on London Bridge, Metropolitan Police Assistant Commissioner Mark Rowley said in a statement.
The suspects then left the vehicle and "a number of people were stabbed, including an on-duty British Transport Police officer who was responding to the incident at London Bridge," said Rowley. The officer received serious but not life-threatening injuries. "Armed officers responded very quickly and bravely, confronting three male suspects who were shot and killed in Borough Market," said Rowley. "The suspects had been confronted and shot by the police within eight minutes of the first call. The suspects were wearing what looked like explosive vests but these were later established to be hoaxes."
