Commons Leader David Lidington has told MPs a "police officer has been stabbed" and the "alleged assailant was shot by armed police" following a "serious" incident within the parliamentary estate.
Minutes later, an emergency services helicopter landed in Parliament Square, as sirens were heard outside.

Air ambulance medics came from the helicopter to assist the casualties.
Two people lay on the ground in the yard. One of them appeared to have had clothes removed as emergency workers attempted to resuscitate the pair.
Parliament Square was closed to traffic.
Our corespondent Lizzie Dearden is making her way to Westminster.
She says people are calm despite multiple helicopters flying overhead.
A witness, who was in the Commons for a job interview, told The Independent: "I was about to leave out of Westminster Hall then loads of people came through screaming."
He said they were tourists and are now being held in the Central Lobby.

Eyewitness video has shown five people being "mown down" by a car on Westminster Bridge.
Radoslaw Sikorski posted a video to Twitter purporting to show people lying injured in the road on Westminster Bridge.
Mr Sikorski, a senior fellow at Harvard Centre for European Studies, said he saw at least five people lying on the ground after being "mown down" by a car.
"I heard what I thought what I thought was just a collision and then I looked through the window of the taxi and someone down, obviously in great distress," he told the BBC.
"Then I saw a second person down, and I started filming, then I saw three more people down, one of them bleeding profusely."

Deputy Presiding Officer Linda Fabiani says security at Holyrood is "under review" in light of Westminster incident
Kevin Schofield, the editor of PoliticsHome.com heard "a very loud bang" from the press gallery inside the Houses of Parliament followed by lots of shouting and men running around.
He initially thought it was a car crash but then he looked outside the window to a heavily-guarded area outside which is out of bounds to the public.
He told Sky News: "Someone rushed through, attacked a policeman, a policeman went down, another policeman came and he was rescued.
"The man who had assaulted him got up and he appeared to be carrying either a knife or a gun. Then we heard gunfire, lots of gunfire, maybe five or six rounds.
"All I remember seeing is the man approaching the police officer probably with a knife and then there was gunfire.
"He was walking towards a second policeman with his arm outstretched, with what looked like a knife in his hand, having already assaulted another policeman.
"It was at that moment that you realised that something serious was happening - a man had broken in to Parliament and had a weapon."
