At least 59 people have been killed and another 527 injured in a mass shooting at a Las Vegas concert.
A gunman, named as 64-year-old Nevada resident Stephen Paddock, opened fire from the 32nd floor of the Mandalay Bay Hotel towards an open-air music festival attended by 22,000.
He killed himself as police stormed the room where 10 guns were found. Investigators have found no link to international terrorism, despite a claim from so-called Islamic State.
In an address from the White House, President Donald Trump described the attack as “pure evil”.
He praised the efforts of the emergency services, saying their “miraculous” speed saved lives, and announced he would be visiting Las Vegas on Wednesday.
With First Lady Melania by his side, he later observed a moment of silence on the White House lawn.
