An video grab obtained from the Twitter account of Polish politician and journalist Rados?aw Sikorski, shows a man on the ground receiving assistance on Westminster Bridge on March 22 in London during an incident. British police shot a suspected attacker outside the Houses of Parliament in London after an officer was stabbed in what police said was a "terrorist" incident. The building in the heart of the British capital was immediately sealed off and MPs and staff ordered to remain inside. TV pictures showed traffic halted on the nearby Westminster Bridge and emergency vehicles swarming around. The busy bridge was completely shut off to traffic.
