A woman with "serious injuries" has been pulled from the River Thames after jumping from Westminster Bridge to escape the London Parliament "terrorist attack".
The woman, whose age currently remains unknown, is said to either have jumped or been forced into the river by some means during the 'terror' chaos.
While she was pulled form the river by the Port of London Authority alive, a spokesman confirmed her injuries were "serious".
A spokesman for the Port of London Authority, which looks after safety on the River Thames, said: "A female member of the public was recovered from the water near Westminster Bridge. She is alive but undergoing urgent medical treatment on a nearby pier. He said the river has been closed from Vauxhall to Embankment "as part of the security response".
Police officers said they had received a number of calls about a person being seen in the water.
Steve Voake, 55, was walking across the Westminster Bridge towards the South Bank when he saw the aftermath. He said that he had seen a person in the water, as well as at least two bodies lying on the road and one in the water.
"I saw a trainer lying in the road and when I looked more closely I saw that there were a couple of bodies the other side of the road," he said.
"And when I looked over the side there was another body lying in the water with blood all around it."
