Ariana Grande has expressed her sorrow at the deaths of 22 people in an explosion after a show in Manchester.
The US star is thought to be physically unhurt, but has posted a tweet saying: “Broken. from the bottom of my heart, i am so so sorry. i don’t have words.”
The blast happened just after the 23-year-old singer had finished performing at Manchester Arena on Monday evening.
Her manager Scooter Braun has also posted a statement, saying “our hearts are broken”.
The arena was packed with thousands of her fans at the time – including a large number of teenage girls, who make up most of her fan base.
Mr Braun continued: “Words cannot express our sorrow for the victims and families harmed in this senseless attack.
“We mourn the lives of children and loved ones taken by this cowardly act.
“We are thankful for the selfless service tonight of Manchester’s first responders who rushed towards danger to help save lives.
“We ask all of you to hold the victims, their families, and all those affected in your hearts and prayers.”
