Several people have been killed after explosions were heard inside Manchester Arena at the end of an Ariana Grande gig tonight.
Video footage showed people fleeing in tears from the venue after bangs rang out immediately after the concert finished.
Bloodied concertgoers were pictured being helped by emergency services outside the gig and armed police were seen patrolling the arena.
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.
'We could hear the police and ambulance sirens. It was terrifying.
'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.'
Manchester's Victoria station, which backs onto the arena, has been evacuated and all trains cancelled.
Greater Manchester Police said: '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.'
Jonathan Yates, 24, from the Wirral, who attended the gig, told MailOnline: 'The concert had finished and the lights came on almost instantly. There was a bang, a weird bang. There were lots of balloons but I thought to myself that can't be a balloon, that's not normal.
'We were sat on the floor level and it came from the higher seats, people were running and screaming. Everyone stopped and I turned to my friend and said 'we need to run'. Everyone was running and screaming and then when we got out it felt a bit more OK.
'I heard five or six bangs that sounded like gunshots. When we got outside people were outside, crying and on their phones.
'You don't think it's something that's going to happen when you go...it was such a nice, fun concert.'
