Palls of smoke hung over the Monte Carlo hotel and casino in Las Vegas after a fire tore through the upper part of the building on Friday morning.
The fire, which broke out at about 1100 (1900 GMT), raged through the roof and top floor of the 3,000-room hotel complex.
Although the thick plumes of smoke from the blaze sparked panic in some guests and residents around the complex, the flames were quickly contained by firefighters.
Guests and staff were quickly evacuated and the fire was largely extinguished within an hour.
But its effects were felt further afield: neighbouring hotels were evacuated and the famous Las Vegas Strip was closed to traffic.
Unlike the fire at Las Vegas' MGM Grand Hotel in 1980, which claimed more than 80 lives and injured nearly 700 people, no injuries were reported in Friday's blaze.
