Salman Abedi, a 22-year-old Briton of Libyan descent, blew himself up as fans were leaving Grande's concert at Manchester Arena on May 22, 2017.
Manchester [United Kingdom]: About 3,500 choir singers have come together to lead a chorus of amateur voices for a mass sing-along as Manchester marked the first anniversary of the arena bomb attack that killed 22 people.
Less than two weeks later, Grande helped organize the all-star "One Love Manchester" benefit concert, raising millions to help victims of the deadly terrorist attack and their families. "Thinking of you all today and every day", she wrote, with an emoji of the bumblebee which is a symbol of Manchester. "I love you with all of me and am sending you all of the light and warmth I have to offer on this challenging day".
Pirate FM has held a minute's silence to remember those who lost their lives.

"You who were hurt or bereaved 12 months ago today are forever part of Manchester, forever part of us", said bishop of Manchester David Walker. To cheers, Manchester United great Ryan Giggs said: 'Manchester is a city of music and is a city of love, and we are sending out love and prayers on this emotional day'. "Love you so very much".
"Nobody will ever forget what happened but the way Manchester pulled together shows you everything you need to know about the people here".
Photographs of those who died in the bombing were displayed on screens in the cathedral shortly before the silence and 22 lit candles on the altar represented each one of the victims, which were made using wax from the thousands of candles left in St Ann's Square in their memory last May.
Some of the hundreds of those injured in the explosion, and the families of those killed, attended a remembrance service at Manchester Cathedral alongside the Duke of Cambridge and Prime Minister Theresa May.
Around an hour and a half later, at 10.31pm, bells on Manchester Town Hall, St Ann's Church, and St Mary's RC Church rang to mark the time the bomb went off one year ago.
