BREAKING: Explosion at Ariana Grande Concert in England

Details are unclear at the moment, but a possible explosion at an Ariana Grande concert in Manchester, England has sparked a panic that has left several people dead.

Reuters reports:

“We were making our way out and when we were right by the door there was a massive explosion and everybody was screaming,” concert-goer Catherine Macfarlane told Reuters.

“It was a huge explosion — you could feel it in your chest. It was chaotic. Everybody was running and screaming and just trying to get out.”

Manchester Arena, the largest indoor arena in Europe, opened in 1995 and has a capacity for 21,000 people, according to its website. It is a popular concert and sporting venue.

A spokesman for Ariana Grande’s record label said that the singer was “okay”. A video posted on Twitter showed fans screaming and running out of the venue.

Authorities have confirmed an unspecified number of casualties in the panic to get out of the building, though what exactly set off this tragedy remains unknown. The possibility of terrorism is of course at the forefront, although an attack of any kind has not been confirmed.

Video from within the arena of concertgoers attempting to flee has not yet captured any footage of smoke or flames, though one eyewitness claims to have smelled burning. Several witnesses report some sort of loud noise, though some say there was only one and others report hearing two noises. Among the theories floated so far is a balloon colliding with an electrical cable.

ABC News has another key detail:

Andy Holey, an eyewitness, told the BBC that he was waiting outside the concert and was blown over by the force of what he described as a “blast” from near the box office. When he awoke, he said he saw many casualties around him. He added that it was unclear if they were injured or dead.

TFPP will continue to follow the story as it unfolds.
