Manchester Police have confirmed that 19 people have been killed in the explosion at Ariana Grande's Manchester concert.
The nearby Holiday Inn has reportedly taken in dozens of concertgoers caught up in the rush to exit the scene, and local taxi companies have offered free rides to help clear the area.
But anxious parents, relatives and friends have turned to Twitter to help find their missing loved ones.
And the social media call-out appears to be working, with reports of several missing concertgoers now found.
