Parents of children who attended Ariana Grande's concert in Manchester have been left stunned by the deadly explosion.
At least 19 people have been killed and dozens others injured after a suspected suicide blast shortly after the concert ended on Monday night (local time).
Witnesses said the explosion left bodies scattered everywhere, with the casualties mostly young girls.
One father who went to the concert with his two daughters, Sophie and Abigail, told local media he was in disbelief after the attack.
"Why? What's the point?" he said.
"I mean, we brought our children out for a day out thinking we'll have a really good concert, they'll remember the concert but probably for the wrong reasons. Innocent people."
His daughter Sophie said people were getting up to leave when there was a "big bang".
"All of the seats shook and everyone just started running, people were screaming and crying," she said.
Local police are currently treating the blast as a possible terrorist act.
