ISIS Claims Responsibility for Attack at Ariana Grande Concert That Killed 22, Suspect Arrested

The explosion that occurred Monday night at an Ariana Grande concert in Manchester has now reportedly killed 22 people and injured 59 people. Two victims have already been named: an 18-year-old woman named Georgina Callander and the eight-year-old Saffie Rose Roussos. At least twelve children are believed to be among the injured as well.

Late Tuesday night Grande, who was reported by TMZ to be in hysterics after the show, responded to the attack, tweeting:

The explosion, which occurred at the end of Grande’s set at the Manchester Arena, has been determined to be a suicide bombing. On Tuesday morning the Islamic State group claimed responsibility for the attack, alleging that they planted bombs in the venue, though the police described an “improvised device” being used in the attack. ISIS also claimed higher fatalities and injury counts than Manchester authorities.

A suspect—a 23-year-old man—has also been arrested in connection with the attack according to Manchester police:

Prime Minister Theresa May condemned the attack, saying, “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.”
