Ariana Grande concert explosion: Final moments before blast

Video has emerged of the end of Ariana Grande's show, only minutes before a suicide bomber targeted the Manchester Arena.

Twenty two people have been killed, including children, after a suicide bomber set off a blast near the exit on Monday night (local time).

Grande ended her concert with a performance of her hit song 'Bang Bang', which was originally performed with fellow popstars Nicki Minaj and Jessie J.

The bright lights and high energy of the performance are a sharp contrast to what came moments later.

As attendees began pouring out of the arena, a blast rang out.

It's believed the bomber, who died detonating the device, was targeting fans as they left through the foyer.

Police are currently treating the blast as a terror attack.
