Las Vegas shooting

At least 2 dead, 24 injured following mass shooting at Las Vegas music festival

UPDATE 7 a.m.: Las Vegas law enforcement said at least 50 people were killed and more than 200 injured, making it the deadliest mass shooting in U.S. history. Our original report is below.

At least two people were killed and 24 injured late Sunday following a mass shooting at the Route 91 Harvest Music Festival in Las Vegas, 12 of them critically, a local hospital spokeswoman told The Associated Press early Monday.

The Las Vegas Metropolitan Police Department tweeted that one suspect is down, and there is still an active investigation around the Mandalay Bay Resort and Casino. At a short briefing, Las Vegas Police Sgt. Jeff Clark said there were "numerous" victims and asked local residents to avoid the area. The Las Vegas police later tweeted, "At this time we do not believe there are any more shooters." Police have shut down the southern part of the Las Vegas Strip and Interstate 15 near the shooting, and flights have been stopped coming in and out of adjacent McCarran International Airport.

A witness at the festival told NBC Los Angeles he heard popping noises, then a pause, followed by rapid-fire automatic gunshots. Other festival-goers reported seeing muzzle flashes from an upper floor of the Mandalay Bay hotel.
