Ariana Grande took to social media Monday night to express her sorrow over a deadly explosion that killed at least 22 people – including children – and injured 59 after her concert at England's Manchester Arena.
"Broken," tweeted the pop star, who was not hurt in the incident. "From the bottom of my heart, I am so so sorry. I don't have words."
Her manager, Scooter Braun, also issued a statement.
"Tonight, our hearts are broken. Words cannot express our sorrow for the victims and families harmed in this senseless attack," he wrote.
"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."
According to The Associated Press, the blast, which occurred about 10:30 p.m. after Grande's show, is believed to be a terrorist attack carried out by a male suicide bomber, police said early Tuesday.
