Suicide bomber strikes at Manchester Arena: Twenty-two people are killed and 59 injured in terror attack as 'nail bomb near the exit' explodes, ripping into teens leaving packed Ariana Grande gig (photos)

Casualties are stretchered out of the concert on Monday evening after a terror attack in the Ariana Grande concert
At least 22 people - including children - are dead and 59 more injured after a suicide bomber targeted youngsters leaving a packed pop concert at Manchester Arena last night in Britain's worst terror attack since 7/7.

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 after the Ariana Grande performance ended.

The bomb went off just after the end of the concert at a time parents were leaving with their children and other mothers and fathers were arriving to pick up groups of youngsters.

Police this morning confirmed that the suicide bomber died inside the arena after an improvised explosive device was detonated.

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'.

Hundreds of people are now desperately searching for loved ones in the aftermath of a terror attack at Manchester Arena which left 22 dead and at least 59 injured.

One eyewitness told MailOnline she saw a young girl screaming 'I don't know where my sister is' while she sprinted out of the venue.
