US-Mandalay-Bay-Flooding, 4th Writethru@

LAS VEGAS -- No events have been cancelled at the convention centre in the Mandalay Bay casino-resort in Las Vegas that flooded Tuesday because of a water main break.

MGM Resorts International spokesman Brian Ahern says the convention centre "is proceeding with its normal events and operations schedule Wednesday."

The break dumped water onto the first floor of the convention area Tuesday evening, and about a thousand people on the second floor had to be relocated.

No injuries were reported, and no hotel rooms were affected.

Clark County fire officials reported no structural damage to the building, although there was damage to part of the first-floor ceiling.

In October, a gunman opened fire from the 32nd floor of the casino-resort into a crowd below at an outdoor concert, killing 58 people.
