LAS VEGAS - A fire on the roof of the 32-story Monte Carlo hotel-casino forced guests and gamblers to flee and sent flaming debris raining down, but the blaze eased after about an hour and no serious injuries were reported.
The mid-morning fire quickly spread across the rooftop facade, made of a foam building material. Orange flames lapped at the hotel's name in large script.
"As we go out of the danger zone, we'll methodically check each floor," Clark County Fire Chief Steve Smith said in declaring the fire contained. "No rooms are burning."
Five people were hospitalized, including four who reported difficulty breathing and one with an unspecified minor injury, said John Wilson, general manager of ambulance companies American Medical Response and Medic West.
"All of them were as a result of the evacuation," Wilson said, "not because of the fire itself."
Officials went door-to-door evacuating the hotel, said Gordon Absher, a spokesman for the resort's owner, MGM Mirage Inc.
Larry Wappel, 25, of San Pierre, Ind., said he and his brother, Eric Wappel, were in a room on the 30th floor when they heard housekeeping staff banging on doors and yelling "Fire, get out!" He said it took about 10 minutes to walk single-file down the stairs to get to ground level.
"There were a couple of ladies crying, but it was pretty calm," he said.
Another guest, Renza Badilla, 45, said she exited through the hotel kitchen to find burning debris and embers falling from the roof.
"I think people were shocked when they saw the smoke," said Badilla, who said she was in the buffet on the main casino level when fire alarms sounded.
Investigators were trying to determine whether the fire had simply burned the resort's facade or penetrated rooms in the upper floors, which contain suites. Guests were being taken the MGM Grand Garden Arena and employees were evacuated to the adjacent New York-New York hotel, Absher said.
There was no immediate indication of criminal activity or arson, Smith said. He called it an external fire but said heat and smoke set off alarms and sprinklers inside the building.
The facade was made of a foam building material that "melted off the side of the building and started a few fires below," Smith said.
Huge crowds formed to watch the fire, and traffic on the Las Vegas Strip was gridlocked as streets were blocked off around the hotel.
The nearby resorts Bellagio and New York New York were not evacuated.
The Monte Carlo Resort & Casino has 3,002 guest rooms and 211 suites. The resort, located on Las Vegas Boulevard, near Tropicana Avenue, opened in June 1996.
The casino-hotel modeled after the Place du Casino in Monte Carlo, Monaco, was a joint venture between Steve Wynn's Mirage Resorts and Circus Circus Enterprises.
The Monte Carlo is down the street from the scene of Nevada's deadliest fire, a Nov. 21, 1980, blaze that killed 87 people at the old MGM Grand hotel and led to strict fire codes in Las Vegas resorts.
That hotel was rebuilt and sold in 1985 and renamed Bally's. It is now owned by Harrah's Entertainment Inc.
