A woman has died on Westminster Bridge in central London in what police are treating as a terrorist incident.
A police officer was also stabbed in the nearby Houses of Parliament by an attacker, who was shot by police.
The attacker struck several pedestrians as he drove a car across the bridge, before crashing it into railings.
A doctor at St Thomas’ Hospital said a number of other people were hurt – some with “catastrophic” injuries.
Junior doctor Colleen Anderson from St Thomas’ said she also said she treated a police officer in his 30s with a head injury, who had been taken to King’s College Hospital.
She said the woman had died at the scene.
