At least 50 people were killed and more than 200 wounded in a mass-shooting attack at a country music concert in Las Vegas late Sunday night.
A gunman opened fire with a fully automatic weapon at concert-goers attending a country music festival at the Mandalay Bay resort just before 10:30 p.m. local time.
The shooting apparently targeted the Route 91 Harvest festival, and began during the performance of country music singer Jason Aldean.
Local police have called for those in the vicinity of the shooting to evacuate.
“We're investigating reports of an active shooter near/around Mandalay Bay Casino. Asking everyone to please avoid the area,” Las Vegas Metropolitan Police tweeted.
Authorities say 50 fatalities have been confirmed, and that some 200 people were wounded. Fourteen of the wounded are in critical condition. University Medical Center spokeswoman Danita Cohen reported that the hospital had taken in “several” victims with gunshot wounds.
The Las Vegas shooting surpassed the 2016 Orlando nightclub shooting to become the deadliest mass shooting in American history.
One witness told KSNV-TV he believed there were multiple shooters, saying that hundreds of rounds had been fired at the audience.
"Clip after clip after clip after clip, bullets flying everywhere, everybody running. It was really bad."
Bullets were "ricocheting everywhere... they were firing from somewhere high and they were unloading clip after clip after clip… multiple shooters, has to be…[there were] hundreds of shots.”
Others told Fox News that they had seen a concertgoer shot in the head.
Police have shut down part of the Las Vegas Strip and are searching for the gunman. McCarran International Airport has temporarily suspended all landings and takeoffs, airport officials reported.
Police say that one suspect was shot and killed on the 32nd floor of the Mandalay Bay resort, adding that no additional shooters are believed to be at large.
Authorities have identified the shooter as 64-year-old Stephen Paddock of Mesquite, Nevada.
