Las Vegas is reeling from the worst mass shooting in US history, with police saying the shooter, Stephen Paddock, acted alone and not following any orders.
The mass shooting left at least 59 people dead and at least 586 injured.
The shooter, 64-year-old Stephen Paddock was found dead at the hotel, where he was holed up for hours with dozens of guns, including several assault rifles.
His girlfriend, Marilou Danley, had been in a car with Paddock when he started shooting at police and civilians, according to authorities.
The FBI has said Paddock was an unstable individual with mental health issues.
He had been found dead in his hotel room.
In a statement, the FBI said they have launched an investigation into Paddock’s background and the shooting.
The bureau has been conducting its own review of Paddock’s activities, but it has not released any details.
“While we do not have any further information at this time, the bureau will work with the public and law enforcement to gather the facts,” it said.
In the aftermath of the shooting, there have been calls for a new round of gun control measures in the US.
Some commentators have argued that the country needs to tighten the security at gun shows and online.
“This is a national tragedy,” said Senator Bernie Sanders.
“We must put our guns away and stop this madness.”
