4 dead, at least 20 injured in UK Parliament attack

BREAKING NEWS - At least 20 people were injured and four reported dead in London on Wednesday after a car crashed into pedestrians near the British parliament and an assailant stabbed a policeman in what police called a terrorist incident.

The knifeman was then shot by police in the shadow of Big Ben, where he had tried to force his way into a courtyard just outside the Houses of Parliament.

The incident appeared to have unfolded in several locations, including on nearby Westminster Bridge where eyewitnesses said a car had crashed into pedestrians.

Reuters reporters inside parliament heard loud bangs and shortly afterwards saw two people lying on the ground in a courtyard just outside.

A Reuters photographer said he saw at least a dozen people injured on the bridge. His photographs showed people lying on the ground, some of them bleeding heavily and one under a bus.

Sky News reported two people had died, but the total number of casualties was unclear. The London Ambulance Service said it had treated at least 10 people on the bridge. (READ MORE)
