A severe dip in Las Vegas tourism and apparent infighting among the owners of the Aladdin hotel-casino has prompted the 2,567 room resort to say for the first time it might have to close just 13 months after opening.

While the Aladdin's closing still is considered unlikely by analysts, the possibility was raised in a report filed by the SEC.

Th filing came a day after the Aladdin laid off 500 workers.
