Thousands of people have shown their solidarity with Manchester at the emotional vigil in Albert Square.
Greater Manchester Police's Ian Hopkins told a vigil in the city: "As your chief constable of Greater Manchester and as a father I cannot begin to imagine how anyone can carry out such an unthinkable act - murdering 22 people and injuring 59 - and my thoughts, and those of my colleagues, are very much with their families at this incredibly difficult time."
Manchester's Victoria Station will be closed "for several days" as a result of last night's bomb attack.
The station is attached to Manchester Arena, where the blast occurred.
Liam Sumpter, director of rail operator Northern, said: "We are working to provide as many services as possible while the station remains closed, but customers need to be aware that there may be some short-notice cancellations and delays."
The station is used by about 21,000 passengers a day, and Metrolink trams will also not operate through the station.

Staff were called in through the night by each hospital and they all came in, and, in fact, more than were needed.

They're saying that sums up the spirit of Manchester.
