Two members of the public have died in a stabbing attack at London Bridge, in which police shot dead the suspect.

A further three were injured in the attack - declared a terrorist incident - and are being treated in hospital.

The suspect, who died at the scene, was wearing what is believed to have been a hoax explosive device, police said.

Videos on social media appear to show passers-by holding down a man. An officer arrives, seems to indicate to the group to move, and fires a shot.

Met Police Commissioner Cressida Dick said the attack began at Fishmonger's Hall on London Bridge, with police called to the incident just before 14:00.
