A knife-wielding attacker was shot by armed police in the grounds of Parliament today after pedestrians were mowed down on Westminster Bridge.
An intruder with a knife managed to break into the grounds of the Houses of Parliament and stabbed a police officer before he was shot, reports suggest.
More than 10 people are said to have been hit by a car on Westminster Bridge after a vehicle described as a '4x4' reportedly drove into pedestrians and cyclists.
Three injured people were also visible on the floor outside Parliament and the Palace was placed on an immediate lock down.
Prime Minister Theresa May is said to have been bundled into a car by a plain-clothes police officer and driven quickly from the scene.
