An eyewitness to the chaos outside Parliament yesterday has told talkRADIO there was "deadly silence" on Westminster Bridge, "just a load of people lying on the floor."
Graham Neale told Paul Ross about what he saw during the attacks, while have left five people dead and 40 injured after a man drove a car into pedestrians on Westminster Bridge before fatally stabbing PC Keith Palmer.
Neal said: "It was a peculiar situation. I walked straight out of the building, straight across the road, and just after I crossed the road, there was a surge of people behind me.
"I heard a sort of slapping sound, which in retrospect was the sounds of gunfire. I looked over towards Big Ben to see coppers running, so I knew something had gone off.
"I turned and started walking across the bridge, except there was no traffic moving and there was deadly silence. There were just a load of people lying on the floor.
"I'm really shocked. I'm a Londoner. I see these people all day long, and feel a real affinity with them, and I choked."
