The Manchester Arena bombing occurred on May 22, 2017, during a concert by the singer Ariana Grande. A suicide bomber detonated an explosive device in the arena's foyer, resulting in the deaths of 22 people and injuring over 800 others. The attack was carried out by Salman Abedi, who was later identified as a member of the extremist group ISIS. In response to the bombing, the UK government raised the terror threat level and increased security measures at public events. The tragedy prompted a global outpouring of support, with many memorials and tributes held in honor of the victims and their families.
