Live video: At least 20 dead and more than 100 injured in Las Vegas shooting on Sunday night

A gunman reportedly opened fire on concertgoers at a country music concert in Las Vegas strip around 10pm on Sunday, which left at least 20 dead and left more than 100 injured.

The snipper styled gunfire rained down from the Mandalay Bay hotel and Casino around 10pm local time according to police report.

The Strip has been completely shut down after the sniper opened fire on the Route 91 Harvest country music festival from the 32nd floor of the Mandalay Bay resort and casino, located across a junction from the event.

Police confirmed that one suspect had been killed, and said at 12:38am that they believed there were no more shooters. Reports of shootings at other locations were unfounded, police said.

The shooter was killed after cops breached at the Mandalay Bay with explosives.

Police are now looking for a woman named Marilou Danley, whom they believe may have information that could help their investigation.
