This is the moment country singer Jason Aldean was forced to cut his performance in Las Vegas short as the concert turned into a bloodbath.
Aldean had taken to the stage of the Route 91 Harvest Festival around 9.40pm and had been playing for about an hour when the first shots rang out.
Video taken from the back of the audience shows people crowded in front of the stage before what sounds like fireworks starts in the background.

‘I still don’t know what to say but wanted to let everyone know that me and my crew are safe. My thoughts and prayers go out to everyone involved tonight.
‘It hurts my heart that this would happen to anyone who was just coming out to enjoy what should have been a fun night. #heartbroken #stopthehate.’
It is believed the lone suspect opened fire from the 32nd floor of the Mandalay Bay Hotel, located across The Strip from the festival.
Police say the suspect is now dead and they are not looking for anyone else. It is not clear if officers shot the suspect, or if he turned the weapon on himself.
Witnesses told how shots were heard at the back of the concert venue and said they saw the dying and injured lying on the floor.

Speaking on a bus laid on to transport concert goers away from the scene, Lisa Price, 43, and Nancy Stover, 38, of Los Angeles said: ‘People were lying on the ground – I was like get up, you’re going to get trodden on.
‘We just heard like pop, pop, pop, pop and started walking – it was happening over and over again.
‘It was at least 20 shots. Enough for us to start walking, then running and panicking. ‘Luckily, we seemed to be further away – we were at the front of the concert near the stage.
‘It seemed to be coming from the back. We were running to try to help people and they were coming from that direction.’
