>> From disposal teams combing the area around the Manchester Arena in Northern England in the early hours of Tuesday morning. Hours earlier, scenes of chaos as fans at an Ariana Grande concert run for safety. At least 22 people have been confirmed dead and around 60 injured after an explosion rang out as the gig came to an end.
Islamic State now claiming responsibility for the attack and saying an explosive device was planted at the concert. Police have arrested one man. I'm Lucy Fielder reporting for Reuters from outside the Manchester arena. This is where US singer, Ariana Grande, had just finished giving her concert when the bomb went off.
And witnesses described scenes of panic, people stumbling and falling on the floor as they struggled to get out of the arena. It's particularly shocking because she has a very young fan base, and we now know that children and young teens were among the dead, including a girl of eight years old.
It's the deadliest attack of its kind in the UK since 52 people were killed by suicide bombers in London, in 2005. Ariana Grande says she's broken over the tragedy, tweeting, I'm so, so sorry. I don't have words. Meanwhile, fans who were at the concert have been speaking about their experience.
>> I was like, we need to run, so we started running. We ran straight out the doors, all the way down to the hotel. And all I could hear was screaming, people crying. Everyone was just running everywhere, it was completely madness.>> The blast took place very close to where a large IRA bombing was carried out in 1996.
That attack involved the largest bomb to be detonated in peacetime. That led to the redevelopment of this area around Manchester and some of the buildings, including the Manchester Arena. Britain's political parties have agreed to suspend campaigning ahead of the general election on June the 8th. The country is on its second highest alert level of severe, meaning authorities believe a militant attack is highly likely.
