Children were among 22 people killed in a suicide bombing at a pop concert in the British city of Manchester, the country's deadliest terror attack in 12 years.
The Manchester incident comes almost two months after an assailant killed five people outside Parliament in London, the first mass-casualty attack since the 2005 London bombings.
Joseph Carozza, a representative from Grande's US record label, said the singer is OK and they are investigating what happened.

Brown posted on Facebook, next to a picture of her smiling face.

Ajax also tweeted, saying: "From Amsterdam with love to Manchester". The US Department of Homeland Security, Britain's biggest intelligence partner, said it was "closely monitoring" the situation. If one part is in pain, the rest of the body is in pain as well.
Harry Potter author J.K. Rowling was one of many British artists and celebrities to help spread the word by retweeting messages and posting offers of help. The person died at the scene.
