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.
“There were people across the bridge. There were some with minor injuries, some catastrophic,” she added.
“Some had injuries they could walk away from or who have life-changing injuries. There were maybe a dozen [injured].”
