MANCHESTER, England — Authorities said Lybian origin Salman Abedi, 22, was the suspected suicide bomber.
The suicide blast in Manchester killed at least 22 people, including teenagers and others streaming out of a pop concert.
The blast occurred about 10:30 p.m., minutes after pop star Ariana Grande had finished her set and many fans were gathered in the foyer to buy concert merchandise.
The Manchester Arena is one of Europe’s largest indoor venues with a seating capacity of 21,000.
British Prime Minister Theresa May called the carnage a callous terrorist attack. Other condemnations from other leaders poured in from around the world.
“This attack stands out for its appalling, sickening cowardice deliberately targeting innocent defenseless children and young people who should have been enjoying one of the most memorable nights of their lives,” the prime minister said.
She mentioned that authorities believe they know the identity of the assailant, “but at this stage of their investigations, we cannot confirm his name.”
The Greater Manchester Police said in a statement that they arrested a 23-year-old man in south Manchester in connection with the attack, as hundreds of police swarmed through the city in the aftermath of the blast.
The casualties carried ages as young as elementary school students. Police said that among the 59 people injured, a dozen were under 16 years old.
Among those killed, Georgina Callander, an 18-year-old student, was the first victim to be named. British media also reported that an 8-year-old girl, Saffie Rose Roussos, could have been the youngest fatality.
“We believe at this stage the attack last night was conducted by one man,” Greater Manchester Police Chief Constable Ian Hopkins said at a televised news conference. “We believe the attacker was carrying an improvised explosive device, which he detonated, causing this atrocity.”
