London terrorist attack
On Thursday morning, Britain's Metropolitan Police counterterrorism chief Mark Rowley said that seven people have been arrested in overnight raids in London and Birmingham in connection with Wednesday's deadly attack outside Parliament and on Westminster Bridge.
"It is still our belief — which continues to be borne out by our investigation — that this attacker acted alone and was inspired by international terrorism," he said. "At this stage we have no specific information about further threats to the public." At least four people, including the attacker, were killed when the unidentified man ran down civilians on the bridge in an SUV, scaled the fence around Parliament, and fatally stabbed a police officer, before being shot. Rowley said 29 people were hospitalized and seven remain in critical condition.
