"We heard what sounded like firecrackers and at first we laughed, then we looked down and there was a girl covered in blood right next to us and we started to run," she told Q13 News' Jon Humbert late Sunday night. "We hid behind bleachers. We hid behind plants. We hid wherever we could while trying to run away."

Authorities shut down part of the Las Vegas Strip and Interstate 15.

Some flights destined for the McCarran International Airport were diverted due to the incident, and the airport was temporarily closed.

Concert-goers reported seeing muzzle flashes from the upper floors of the Mandalay Bay and the sound of what they described as automatic gunfire.

"We passed body after body," Cantrell said. "It was awful. There were bodies left and right."

Some later huddled in the basement of the nearby Tropicana hotel-casino.

Witnesses say country singer Jason Aldean was playing near the end of the concert when gunfire rang out.
