Police confirm they are treating the incident as a “terror incident”.
An attack in Manchester on Monday night is the deadliest on British soil since 2005. News has been filtering in since last night and this is what we know so far.
An eyewitness gave his account of what happened to the BBC.
The incident in Manchester at the Ariana Grande is the second terror attack to hit England in less than two months.
In March, five people were killed and more than 50 injured when a man drove into pedestrians on Westminster Bridge in central London. His vehicle then crashed into the gates of parliament. The attacker was shot dead by police. Nobody has been charged in connection with that incident.
