A female pedestrian has died and there are many others with injuries, some of which are “catastrophic”, according to Dr Colleen Anderson from St Thomas’ Hospital.

Shots were heard at about 2.45pm as a policeman was stabbed and his attacker shot by officers.

The attacker mowed down several pedestrians as he drove a grey Hyundai i40 across Westminster Bridge before crashing it into railings, running through the gates of the Palace of Westminster and stabbing the officer.
