BBC:– Two members of the public have died and another three people were injured in a stabbing attack at London Bridge, the Met Police’s commissioner has said.
Cressida Dick told a press conference the stabbing attack, which has been declared a terrorist incident, began at an event at Fishmonger’s Hall.
Within five minutes of being called officers confronted the suspect – who was shot dead at the scene – she said.
The suspect was wearing what is thought to have been a hoax explosive device.
Ms Dick said police were working at “full tilt” to understand what had happened and whether anyone else was involved.
She said officers were still working to identify the dead.
Videos on social media appear to show passers-by holding down a man at London Bridge.
Another man in a suit could be seen running from him, having apparently retrieved a large knife.
Footage then shows an officer arriving, seeming to indicate to the group to move, and firing a shot.
The actions of the public have been widely praised, including by Prime Minister Boris Johnson, Labour leader Jeremy Corbyn and Ms Dick, who said they had shown “extreme courage”.
She added: “Ours is a great city because we embrace each other’s differences.
“We must emerge stronger still from this tragedy. In doing that we will ensure that the few who seek to divide us will never, ever succeed.”
There was no intelligence of anything about to happen, sources say, and police reacted to events as they unfolded.
At the start of this month, the UK threat level was lowered from severe to substantial – reflecting an assessment from the Joint Terrorism Analysis Centre that an attack was likely rather than highly likely because of a relative decline in activity.
The challenge for police and security services is that low-tech attacks – involving knives or vehicles – and often carried out by lone actors can be hard to spot in advance since they involve relatively little preparation and communication.
But in the wake of previous incidents in both the UK and other countries, police have been prepared for this kind of incident and seem to have been fast to intervene, taking few chances, although members of the public were also involved in restraining the individual.
The priority for police and MI5 now will be establishing the identity of the individual, whether he had any links or associations and whether there is any ongoing related threat.
