It's just after 1.30am in Manchester now, so we're going to wrap up our live coverage of the events following Monday night's bombing.
Below is a wrap of the latest information we have about the attack:
- The UK government has raised its terrorist threat level from "severe" to "critical". Prime Minister Theresa May said that "a further attack may be imminent".
- Armed police who usually protect places such as the UK parliament will be replaced by members of the armed forces, and military personnel also may be deployed at public events.
- The death toll from Monday night's attack stands at 22, with a further 119 injured.
- Children are among the dead. The youngest so far identified is eight-year-old Saffie Rose Roussos.
- Police have named the suspected suicide bomber as Salman Abedi, a 22-year-old former student at the University of Salford. He is believed to have been born in Manchester and his family is originally from Libya.
- The Islamic State terror group claimed responsibility for the attack, although authorities are treating this with some scepticism.
- Thousands of mourners have gathered in Manchester's city centre for a candlelight vigil to pay tribute to the victims.
- The Department of Foreign Affairs and Trade now urges a "high degree of caution" for anyone visiting Britain.
