Two members of the public have died after a stabbing attack at London Bridge, in which police also shot dead the suspect.
The Met Police has declared the attack a terrorist incident.
The suspect, who died at the scene, was believed to have been wearing 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.
A Whitehall source confirmed two members of the public died to the BBC but gave no further information.
Details are still emerging and Neil Basu, the head of UK counter-terrorism policing, said the force was keeping an open mind over the motive.
He said officers were called to a stabbing at premises near the bridge just before 14:00.
BBC journalist John McManus, who was at the scene as it unfolded, said he had seen a struggle on the bridge, with several men restraining one man. Police then arrived quickly and a number of shots were fired at him, he said.
In footage shared on social media, the man could be seen being pinned down by members of the public. Another man in a suit could be seen running from him, having apparently retrieved a large knife.
Mr Basu told a press conference: “A male suspect was shot by specialist armed officers from City of London police and I can confirm that this suspect died at the scene.”
He added that a “wide cordon remains in place” following the incident.
Mr Basu said: “Officers continue to carry out extensive searches in the area to ensure there is no further threat to the public.” (BBC)
