What to Know About the Suicide Bomb Attack at Ariana Grande's Concert in Manchester

At least 22 people have been killed in a suicide bomb attack after a concert by Ariana Grande’s in Manchester, England on Monday night. Some 59 people were taken to hospital with injuries and many more were treated at the scene.

Here are some key details:

1. The death toll has reached 22 and includes children

Twenty-two people were killed and at least 59 others were injured in the incident, Greater Manchester Police have said. Chief Constable Ian Hopkins confirmed at a press briefing at 7 a.m. local time (2 a.m. EDT) Tuesday that children were among those killed.

He said the attack was carried out by one man carrying an improvised explosive device (IED), who also died on the scene. He urged the press and public “not to speculate” the identity of the attacker.

The local North West Ambulance Service said on Twitter that it had “taken 59 casualties from the Manchester Arena incident to various hospitals” and “treated a number of walking wounded on scene.” Some 60 ambulances were dispatched after the attack.

2. The incident took place at Manchester Arena

Police received reports of an explosion at Manchester Arena just before 10:35 p.m. local time. The arena — located in the northern English city of Manchester — has a capacity of 21,000 and attracts more than one million people each year, according to the venue’s website.

Officials at the Manchester Arena said in a statement that the incident “took place outside the venue in a public space,” said to be a foyer near the box office.

Witnesses described a chaotic scene as concert-goers fled the arena when they heard a “loud bang” shortly after the concert ended, according to the Manchester Evening News.

“We saw the smoke. Everyone just fled. Some people were injured. We saw blood on people when we got outside. People were just running all over the place,” David Richardson, who was at the concert with his 13-year-old daughter Emily, told the Evening News.

3. Ariana grande has expressed her devastation following the attack

Witnesses said the incident took place shortly after Grande, 23, had finished performing.

Hours after the attack, Grande tweeted: “Broken. From the bottom of my heart, I am so so sorry. I don’t have words.”

Her manager Scooter Braun tweeted a statement, reading in part: “We mourn the lives of children and loved ones taken by this cowardly act.”

Grande is currently on the Dangerous Woman international tour. Her next performance is scheduled for London on Thursday.

4. Campaigning for the U.K. general election has been set aside

British Prime Minister Theresa May called the blast “an appalling terrorist attack.” She will chair an emergency COBRA crisis-response meeting at around 9 a.m. local time (4 a.m. EDT) Tuesday, reports the BBC. Leading political figures from the U.K. and beyond have expressed their shock, grief and solidarity on Twitter overnight.

The BBC says that the major British political parties — the Conservatives, Labour, the Liberal Democrats and the Scottish National Party — have all suspended campaigning for June’s general election.
