New questions are being raised about security measures around the United States Congress after a vehicular assault on a security checkpoint killed one Capitol Police officer, injured another and ended with the driver of the car shot dead.
A couple of minutes after 1pm local time (17:00 GMT) on Friday a man drove a car into a main driveway of the US Capitol plaza, striking two police officers before crashing into a barricade. The man emerged from his car brandishing a knife and lunged at the officers before being shot, police officials said.
Officer William “Billy” Evans succumbed to his injuries, according to acting Capitol Police Chief Yogananda Pittman. The second officer remained hospitalised.
