WATCH: Terrifying amateur video captures moment of Manchester blast
This shocking video footage shows the moment that young concert-goers realised a bomb had exploded at the Manchester Arena last night.
At least 22 people have been confirmed dead and dozens of others are injured after the incident, which happened at the end of a concert by US popstar Ariana Grande.
This footage shows stunned pals hearing the blast and after a moment of confusion they run to the exit.
As they reach the foyer, thousands of others are seeing screaming as they desperately tried to flee the scene to safety.
There are children among the fatalities in the Manchester attack, Greater Manchester Police chief constable Ian Hopkins confirmed in a press conference on Tuesday morning.
Police said they responded to reports of an explosion shortly after 10.35pm at the arena, which has a capacity for 21,000 people, and where the US singer had been performing to an audience that included many children.
