BANGKOK, June 4 (Xinhua) -- One tourist was killed and six others were trapped under debris on Saturday morning after a resort building in Koh Chang Island, east Thailand, collapsed following heavy rainfall, local media reported.

The accident occurred at around 6:00 a.m. local time in torrential rains. The Siam Beach Hotel on Koh Chang Island in Trat Province, 350 km away from Bangkok, tumbled down when the guests were sleeping.

The victim was killed instantly, and six others, including a child, were trapped under the debris.

According to police who raced against time to rescue the victims, the dead is a Thai tourist.

Koh Chang chief district officer Kamthon Waehon said the collapse might be caused by low construction standard as the building was on soft soil and near a cliff.

He said heavy downpours have been hitting the island for several days.

Rescuers have saved four trapped people and sent them to a hospital. They are Chinese tourists, local media mathichon said.
