Manchester Suicide Bombing

On May 23, ISIS claimed responsibility for an explosion in Manchester, England that killed 22 and injured 59, according to initial reports. This is the deadliest terrorist attack in the UK since the London bombings in 2005 and the second ISIS claimed in the country in two months.

  • The suicide operation occurred at approximately 10:30 p.m. local time on May 22, as tens of thousands of people, many of whom were teenagers, exited a concert at the Manchester Arena. The explosive detonated in an area connecting the arena with the Victoria train station, likely outside venue security. Western media identified the perpetrator as Salman Abedi, and the investigation is ongoing.
  • ISIS’s claim adheres to its broader messaging that encourages sympathizers to target the West in response to military action “against the lands of the Muslims.” In the latest issue of the group’s online magazine, Rumiyah, released this month, ISIS cites concert halls as ideal targets, as well as nightclubs, restaurants, and shopping venues.
