At least 50 people have been killed, and more than 200 injured, after a gunman opened fire on an open-air concert in Las Vegas, in the United States.
The gunman, who was named as 64-year-old local resident Stephen Paddock, opened fire from the 32nd floor of the Mandalay Bay Hotel, towards the outdoor Route 91 Harvest Music Festival.
He was shot dead by officers in the hotel, and a number of guns were found.
Sheriff Joe Lombardo described the attack as a “lone wolf” attack, saying that there was currently no indications to Paddock’s motives.
“We have no idea what his belief system was” he told reporters.
A woman believed to have been travelling with Paddock before the attack, named by local media as Marilou Danley, had been located by police, he added.
Two off-duty police officers were among the deceased, though Lombardo told reporters he was unable to give any other accurate details of the dead and injured,
The attack is the worst mass shooting in recent US history.
President Donald Trump tweeted his “warmest condolences and sympathies” to the victims and their families, and called the shooting “terrible”.
