The Manchester Arena bombing, or Manchester Arena attack, was an Islamic terrorist suicide bombing of the Manchester Arena in Manchester, England, on 22 May 2017, following a concert by American pop singer Ariana Grande. Perpetrated by Islamic extremist Salman Abedi and aided by his brother, Hashem Abedi, the bombing occurred at 10:31 p.m. and killed 22 people, injured 1,017, and destroyed the arena's foyer. It was the deadliest act of terrorism and the first suicide bombing in the United Kingdom since the 7 July 2005 London bombings.

The Dangerous Woman Tour was the third concert tour and the second arena tour by American singer Ariana Grande in support of her third studio album, Dangerous Woman (2016). It traveled across North America, Europe, Latin America, Asia and Oceania. The tour started on February 3, 2017, in Phoenix, Arizona, and ended on September 21, 2017, in Hong Kong. The tour was temporarily halted on May 22, 2017, due to a terrorist bombing, which happened minutes after the end of Grande's Manchester Arena show, killing 22 concert-goers and physically injuring 139 others. After organizing and performing at the One Love Manchester benefit concert, Grande resumed the tour on June 7, 2017, in Paris.
