Reports say at least 20 people were killed and hundreds injured in a suspected terrorist attack in the UK.
Huge explosions were heard inside Manchester Arena, in Manchester, at the end of a teen concert late Monday night.
Video footage showed thousands of people fleeing in tears from the venue, many covered in blood, after the concert that featured US singer, Ariana Grande, ended.
Armed officers surrounded the venue and bloodied concertgoers were pictured being helped by emergency services outside the 21,000-seat gig.
Evie Brewster, who attended the concert, told MailOnline: “Ariana Grande had just finished her last song and left the stage when a huge explosion sounded. Suddenly everybody started screaming and running for the exit.
“There were thousands of people trying to get out at once. They were all screaming and crying. The whole place smelt smokey and burnt The explosion sounded like it was inside the building somewhere.”
Multiple law enforcement sources told NBC News that at least 20 people had been killed following the explosion.
Manchester’s Victoria station, which backs the arena, was immediately evacuated and all trains cancelled.
Greater Manchester Police issued a statement saying: “Emergency services are currently responding to reports of an explosion at Manchester Arena. There are a number of confirmed fatalities and others injured.
“Please AVOID the area as first responders work tirelessly at the scene. Details of a casualty bureau will follow as soon as available.”
A spokesman said the explosion happened within the foyer area of the venue. A bomb disposal unit were spotted arriving at the scene.
The BBC reported that senior counter-terror officials are assembling in London tonight.
