At least 50 killed and 200 hurt in mass shooting at Las Vegas shooting

At least 20 people have died in the attack in Las Vegas.

A Las Vegas resident, named as Stephen Paddock, is suspected of being the man who opened fire on the Route 91 Harvest Festival on the Las Vegas Strip.

The suspect was killed by police on 32nd floor of the Mandalay Bay Hotel and Casino, situated across from the concert.

Nevada police also said they have located a "female person of interest" in connection with the shooting.

Marilou Danley, 62, had been sought by police after gunfire tore through the crowd at the outdoor event during a set by country music star Jason Aldean.

The dead gunman is also believed to have checked into the hotel as a guest. Clark County Sheriff Joseph Lombardo said officers confronted Paddock in the hotel.

Dozens of patrol vehicles descended on the Strip after authorities received reports of an active gunman near the music festival.

Concert-goers reported seeing muzzle flashes from the upper floors of the Mandalay Bay across Las Vegas Boulevard from the music festival and the sound of what they described as automatic gunfire.

Kodiak Yazzie, 36, said he and his girlfriend were watching country star Jason Aldean's performance when he heard what sounded like fireworks. The music stopped temporarily and then 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, Mr Yazzie 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.
