A car crashed into a fence outside the Parliament building in London on Wednesday, March 22. One woman has died and many people were injured, the British Press Association said, in what police are treating as a terrorist incident. "It appeared that a car was coming towards the House of Commons mowing down pedestrians on the way," Member of Parliament Gerald Howarth told CNN. "The driver then got access to the parliamentary estate, stabbed a police officer and was shot."

"It seems that a police officer has been stabbed, that the alleged assailant was shot by armed police," the Leader of the House, David Lidington, told MPs.
"An air ambulance is currently attending the scene to remove the casualties. There are also reports of further violent incidents in the vicinity of the Palace of Westminster but I hope colleagues on all sides will appreciate that it’d be wrong of me to go into further details here until we have confirmation from the police and from the House security authorities about what is going on."
Around half an hour after the attack, former Cabinet minister Anna Soubry said on Twitter she and Security Minister Ben Wallace were ordered into the Parliament lobby at gun point by police.
"Colleagues taken out of the library at gun point by counter terrorist armed police officers," she tweeted.
Police said in a statement that a full response unit had been sent to the scene, along with ambulance crews and air ambulances.
"We have declared a major incident and our priority is to assess patients and ensure that they are treated and taken to hospital as soon as possible."
Police appealed for anyone with photos or video of the incident to pass them on to police.
Henry Mance, a political reporter for the Financial Times, told CNN that people inside have been told to stay away from windows.
Member of parliament Sir Gerald Howarth said the House of Commons was in the middle of a vote when the session was suspended and members locked in.
"It appears to be very, very serious indeed. The Leader of the House has told us it’s been confirmed that one police officer here has been stabbed. It appeared that a car was coming towards the House of Commons mowing down pedestrians on the way and the driver then got access to the parliamentary estate stabbed a police officer and was shot," he said.
