The Manchester Arena bombing was a suicide bombing attack in Manchester, United Kingdom on 22 May 2017. A radical Islamist detonated a shrapnel-laden homemade bomb as people were leaving the Manchester Arena following a concert by the American singer Ariana Grande.
Twenty-three people died, including the attacker, and 139 were wounded, more than half of them children. Several hundred more suffered psychological trauma. The bomber was Salman Ramadan Abedi, a 22-year-old local man of Libyan ancestry. After initial suspicions of a terrorist network, police later said they believed Abedi had largely acted alone but that others had been aware of his plans.
The incident was the deadliest terrorist attack and the first suicide bombing in the United Kingdom since the 7 July 2005 London bombings.
