LAS VEGAS — At least 20 people were killed and more than 100 wounded during a shooting at an outdoor music festival on the Las Vegas Strip late Sunday.
The suspected gunman is dead, local Sheriff Joseph Lombardo said at a morning news conference. He has been identified, but officials have not yet released his name.
A woman and two vehicles are still being sought.
Dozens of patrol vehicles descended on the Strip after authorities received reports of an active shooter near the Route 91 Harvest Festival.
Concert-goers reported seeing muzzle flashes from the upper floors of the Mandalay Bay Hotel and Casino across Las Vegas Boulevard from the country music festival and the sound of what they described as automatic gun fire.
Twenty-six people were admitted to the hospital, University Medical Center spokeswoman Danita Cohen said. Of those, at least two died, 12 were in critical condition and the rest were being evaluated, she said.
At least two off-duty officers have been killed, and others who responded to the scene were injured.
A Southern California police department says one of its off-duty officers was shot during the attack on a Las Vegas concert.
Several officers from the Bakersfield Police Department were attending when the gunman opened fire. One was shot and taken to the hospital with non-life threatening injuries. Authorities did not release his name.
Kodiak Yazzi, 36, said he and his girlfriend were watching Jason Aldean's performance when he heard what sounded like fireworks. The music stopped temporarily and started up again before another round of pops sent the performers ducking for cover and fleeing the stage.
Thousands fled as bursts of gunfire could be heard for more than five minutes, Yazzi said.
Witnesses said they saw multiple victims and dozens of ambulances near the concert venue. Some attendees later huddled in the basement of the nearby Tropicana hotel-casino.
Russell Bleck shared video of the shooting on social media.
"Scariest moment of my life. They just kept firing and firing. Please god let everyone be ok," Bleck said in an Instagram post.
Officers carrying assault rifles ran into the Mandalay Bay Hotel and Casino.
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 shooting.
No further information was immediately known.
"Very sad night for Las Vegas," the official City Hall account tweeted.
