Two members of the public - a man and a woman - were killed in the terror attack on London Bridge on Friday afternoon, police have confirmed.

Three others - a man and two women - were also injured and remain in hospital, Metropolitan Police Assistant Commissioner Neil Basu said.

One is in a critical but stable condition, another is stable, and the third suffered less serious injuries.

Met Police Commissioner Cressida Dick praised the "extraordinary courage" of members of the public who tackled the offender. It has since emerged that one of those who pinned him down was an off-duty plain clothes police officer.

The attacker, who has been named by police as 28-year-old convicted terrorist Usman Khan, was shot dead at point-blank range by police. He appeared to be wearing a fake suicide vest.


Mr Basu said in a statement: "The circumstances, as we currently understand them, are that the attacker attended an event earlier on Friday afternoon at Fishmongers' Hall called 'Learning Together'.

"We believe that the attack began inside before he left the building and proceeded onto London Bridge, where he was detained and subsequently confronted and shot by armed officers."

Footage showed members of the public attempting to detain the attacker and taking possession of the bladed weapon.

The video also showed specialist armed officers moving civilians away, aiming their weapons and shooting Khan, who died at the scene.

Witness Celia Sodera was on the top floor of a bus when she saw a plain clothes police officer and members of the public taking the knife from the attacker.

She told Sky News: "We saw six people keeping someone on the floor. At one point someone said 'he has a knife'. And we thought, 'oh my god this guy was going to stab someone' because we saw people running away.

"Then the police came and finally they removed the knife, then they shot the guy.

"He was still alive and he tried to pull the black jacket off so I was able to see the vest he was wearing and it seemed like a very scary device, a bomb device."

Mr Basu said: "As you would expect, due to the nature of the incident, we responded as though it was terrorist-related. I am now in a position to confirm that it has been declared a terrorist incident.

"Officers from the Met's Counter Terrorism Command are now leading this investigation. I must stress, however, that we retain an open mind as to any motive."

He warned that extensive cordons were likely to remain in place for some time - and urged the public to stay away from the area.

In the hours after the terror attack, London Mayor Sadiq Khan praised the "breathtaking heroism" of the passers-by who risked their lives to detain the attacker.

Mr Johnson paid tribute to the bravery of the emergency services and the public.

"Anybody involved in this crime and these attacks will be hunted down and will be brought to justice," he said.

Mr Johnson chaired a meeting of the government's emergency committee Cobra on Friday night and has cancelled his campaigning for the general election while he deals with the fallout from the attack.

The incident comes nearly two-and-a-half years after the 2017 London Bridge terror attack. Eight people were killed and 48 others were injured when a van was driven into pedestrians on the bridge, with the van's occupants running into Borough Market and stabbing people in restaurants and pubs.

Civilian pulled away before police shoot

At the beginning of this month, the UK's terror threat level had been lowered from "severe" to "substantial" for the first time in five years. It meant an attack was considered to be likely instead of highly likely.

The police and the security services have foiled 25 suspected terrorist attacks since Khalid Masood killed four people when he ploughed his car through pedestrians on Westminster Bridge before stabbing to death PC Keith Palmer as he guarded parliament.
