Police say a woman who was one of six Thai tourists at a beach resort in eastern Thailand died when the building in which they were staying collapsed.

Police Lt. Col. Arwat Piboonsawat says the other five people in her party, all Thai, were rescued several hours after the Saturday morning collapse of the two-story building at the Siam Beach Resort on the island of Koh Chang. A 3-year-old boy was one of those recovered from the rubble after a rescue effort of several hours to remove the debris.

The survivors were hospitalized in good condition.

The cause of the building's collapse was under investigation, but it occurred after a heavy rainstorm. Local media reported that officials speculated the rain might have undermined the building's foundation.
