Westminster Correspondent Lindsay Razaq describes how the drama unfolded this afternoon – saying it was like something out of an “America TV show”.
My office overlooks New Palace Yard, which is one of the main entrances to parliament from Parliament Square.
I was just sitting down to watch the Holyrood debate when we heard a car crash, which must have been at Westminster Bridge.
One of my colleagues said ‘what’s going on, what’s going on’ and then we saw all these people swarming through the main gates which were open – normally they’re closed, but there was a car going out.
I think I saw a guy in a black suit, and then I heard two shots.
Two men fell to the ground within seconds of each other. One was a police officer and the other I think was the assailant.
Very quickly, the police officers on guard rushed in to assist the two people and CPR began. The air ambulance came within a few minutes and landed in Parliament Square but no one has been flown away yet as far as I have seen.
They carried on with the CPR on the two guys for half an hour. One of them was taken away in a road ambulance, but the other is still lying outside, with a blanket covering him.
We later saw the police checking the estate for other people, there’s military police too with shields and some sniffer dogs.
Every single building is on lockdown, there’s just been an announcement on the PA system telling us all to stay in our buildings.
It was really, really frightening. It was like something you would see in an America TV show.
