Yahoo News Parliament shooting eyewitness: 'man plunged big knife into policeman'
At least two people have died after a knifeman brought terror to the heart of Westminster, mowing down pedestrians then stabbing a policeman before being shot by armed officers.
Eyewitnesses described scenes of terror as the attacker was shot several times as he approached a second officer within yards of the Houses of Parliament.
Paramedics fought to save his life and that of his victim on the floor of the cobbled courtyard in front of Parliament with Foreign Office minister Tobias Ellwood among those who rushed to help.
Eyewitness Rick Longley described the attack.
"We were just walking up to the station and there was a loud bang and a guy, someone, crashed a car and took some pedestrians out.
"They were just laying there and then the whole crowd just surged around the corner by the gates just opposite Big Ben.
"A guy came past my right shoulder with a big knife and just started plunging it into the policeman.
"I have never seen anything like that. I just can't believe what I just saw."
