London Bridge shooting: What we know so far

A man has been shot dead by police and a number of people have been stabbed in an attack on London Bridge which is being treated as "terror-related".

What happened?

The Met Police said officers were called to a stabbing at a premises near the bridge in central London just before 14:00 GMT.

A number of people have been injured, some seriously.

Videos on social media show members of the public wrestling a man to the floor who then disperse before the man is shot by an armed police officer.

Another man in a suit and jacket can be seen running from him, having apparently retrieved a large knife.

A separate video has also emerged showing police officers aiming guns at a white lorry that jack-knifed across the bridge.

The footage shows several officers surrounding the vehicle before moving to the rear to check its container.

Whitehall officials have told BBC Security Correspondent Frank Gardner the police action was not intelligence-led and was spontaneous and reactive.
