A police officer has been stabbed and a man shot outside the Houses of Parliament in London.
Two people were pictured lying on the ground within Old Palace Yard, just outside Westminster Hall.
Commons leader, David Lidington, told MPs that a “police officer has been stabbed” and the “alleged assailant was shot by armed police” following a “serious” incident in the parliamentary estate.
A number of witnesses have reported seeing a man carrying a knife arguing with police officers, before several shots were heard.
The Metropolitan Police released the following statement on their Twitter.
Officers – including firearms officers – are on scene and dealing with the incident in #Westminster

There are reports of further incidents nearby, and police say they have been called to a firearms incident on Westminster Bridge.
Prime Minister Theresa May was ushered into a car by eight armed police and has since been driven away from Westminster. Other MPs are currently in lockdown in the main chamber.
