Terror attack at Ariana Grande concert in Manchester: What we know

The 23-year-old singer has reportedly pulled out of her next concert, in London on Thursday, and is now planning to reschedule the rest of her European shows.

Concert goers were exiting the venue, which has a capacity of 18,000, following a concert by American pop star Ariana Grande when an explosion took place at around 10:30 pm.

Chief Constable of Greater Manchester Police Ian Hopkins said it was believed that the attacker - a lone male who died at the scene - was carrying an improvised explosive device.

Prime Minister Theresa May said the incident was being treated as a terrorist attack. "Our thoughts and prayers go out to all those affected", said Manchester United, who are in Stockholm ahead of Wednesday's Europa League final against Ajax.

Paula Robinson, 48, from West Dalton about 40 miles east of Manchester, said she was at the train station next to the arena with her husband when she felt the explosion and saw dozens of teenage girls screaming and running away from arena.

Ariana Grande, 23, later said on Twitter: "broken. from the bottom of my heart, i am so so sorry. i don't have words".

How many people have been injured/killed?

At least 22 people have been confirmed dead and 59 people injured in the attack are being treated across 8 hospitals in the Greater Manchester area. This would not rule out that he did so at the order of a terrorist group, or that he had help with planning the attack from a cell in the country.

Police stand by a cordoned off street close to the Manchester Arena.

Police carried out a controlled explosion on a suspect device several hours after the blast but subsequently revealed it had been a harmless bag.

Manchester's Victoria station, which backs on to the arena, was evacuated and all trains and trams cancelled. "It's the most frightful feeling ever, to know your daughter is there and you don't know whether she's dead or alive", she said.

"As I turned around, boom, one loud noise", she told Sky News. "It smelled of burning and there was quite a lot of smoke as we were leaving".

"It's just shocking and we just feel very shaken up".

"Strong, proud, caring people with community at its core", he said.

Calvin Welsford, 18, from Bristol told the BBC: "It nearly sounded like a gunshot".

Facebook has activated its safety check feature so people can let loved ones know they are safe, and an emergency helpline, 0161 856 9400, has been set up for those searching for loved ones.

"I was actually having an asthma attack".

The US Department of Homeland Security, Britain's biggest intelligence partner, said it was "closely monitoring" the situation. "Emergency services are at the scene and we are working to establish more information regarding the explosion and will provide further updates as soon as possible".

Condolences poured in from world leaders.

Prime Minister of India Narendra Modi tweeted his condemnation and sadness over the incident.

Trump, speaking during a visit to Bethlehem, said "evil losers" were behind the attack.

"Broken", said Ariana Grande.
