Ariana Grande has responded to the incident in Manchester that left at least 19 dead and almost 60 injured.

Writing on social media a few hours after police responded to what they said was a reported explosion in the aftermath of her concert at the Manchester Arena, the 23-year-old singer said she was “broken”.

“From the bottom of my heart, i am so so sorry,” she said. “I don't have words.”

Grande escaped unhurt from the incident, which happened shortly after the American singer completed her set and lights in the venue had been switched on. Video taken at the scene showed scenes of chaos and horror. Many of those inside the venue were youngsters or teenagers, and a lot of them were with their parents.
