At least 22 people, including children, were killed in a terror bomb attack at a concert on 22 May (23 May, Singapore time) in Manchester Arena, UK, where US singer Ariana Grande had been performing.

The blast, which was reportedly caused by an improvised explosive device believed to be carried out by a man, injured at least 116 people. The suicide bomber was identified as 22-year-old Salman Abedi who died at the scene.

British police said they believed the device used was made in Manchester with help from others and that there may be more people at large, related to the incident.

British Prime Minister Theresa May said the incident is treated as an “appalling terrorist attack”, making it the “worst attack Manchester has suffered, and the worst to hit the north of England.” It is the deadliest terror attack to hit the UK since the London bombings in July 2005.

The 23-year-old American singer, who was not hurt in the blast, tweeted “broken” in the hours after the attack.

“From the bottom of my heart, I am so so sorry. I don’t have words,” she wrote.

Following the tragic incident in Manchester, a statement from Grande’s management said the singer has cancelled her tour dates up to June 7.

Following the blast on the Manchester Arena, we look back at other recent acts of terror on concerts and clubs.
