- A barbaric attack, deliberately targeting children and some of the most vulnerable.
- Britain's worst terror attack since 7/7.
- 22 dead and scores injured
The blast happened at 22:35 BST on Monday following a pop concert by the US singer Ariana Grande.
Home Secretary Amber Rudd said it was "a barbaric attack, deliberately targeting some of the most vulnerable in our society".
Relatives are using social media to hunt for missing loved ones, including children, caught up in the incident, reports the BBC.
Witnesses told of nuts and bolts tearing into young gig-goers when the blast was detonated in the foyer area between the arena and the next-door Victoria station just after the Ariana Grande performance ended.
One image captured bodies of the dead and injured lying in an area between the arena and the next-door Victoria station, which had been packed with people leaving the venue as the gig wound down. As the explosion tore through the lobby, terrified youngsters stampeded for the sold-out 21,000-seater stadium's exits in horrifying scenes caught on mobile phone cameras.
Witnesses described the carnage as being 'like a war zone'. Armed police, the bomb squad and scores of emergency vehicles descended on the venue in the aftermath of the explosion, which took place at 10:35pm last night, reports The Daily Mail.
