LOS ANGELES, Oct. 1 (Xinhua) -- More than 20 people were killed and more than 100 others were wounded in a mass shooting during a concert Sunday night outside of the Mandalay Bay Hotel in Las Vegas in the U.S. state of Nevada, local police said on Monday.
The key suspect was firing an automatic rifle from the 32nd floor of the Mandalay Bay hotel and was killed by police shortly, police spokesman Joe Lombardo told a press conference.
In video clips posted online, the sound of an automatic weapon being fired can be heard. It was reported that the kind of firearm that made that noise cannot be easily purchased at U.S. gun stores.
Local media reported that the shooting occurred at 11:30 p.m. and ABC 7 news channel reported that there were hundreds of shots.
A female officer of Las Vegas Metropolis Police Department (LVMDP) told Xinhua via phone that she did not know how many people dead and only confirmed "the strip has been closed."
The concert was interrupted after people gathering there run away when they found it was sound of machine gun instead of fireworks.
Earlier, CBS Los Angeles and FOX 11 both said two were killed in the shooting, while 24 were injured and 12 in critical condition.
The report also said another suspect was still at large, but LVMDP tweeted at 00:30 am Monday morning on its official page "we don't believe there are any more shooters."
LVMPD tweeted early that "Please do not livestream or share tactical positions of our officers on scene, this may put emergency responders in danger."
