Metropolitan Police Assistant Commissioner Mark Rowley says that armed officers 'fired 50 rounds' during Saturday night's London attack.

The victim becomes the eighth teenager stabbed to death in London this year.

More than one person has died after a series of incidents in central and south London, including one involving a vehicle, police say.

Armed police are at security incidents at London Bridge and nearby Borough Market. Here is what we know.

Police enter a bar at London Bridge and customers take cover in footage posted on Twitter.

Police have not identified the attacker - but say the incident was a robbery, not a terror attack.

Reporters found the bodies of men, women and children in a street held by so-called Islamic State.

Thousands are to attend the tribute concert, headlined by Ariana Grande, 13 days after the attack.
