Search and rescue teams were looking Sunday for a dozen members of a youth soccer team who were missing and believed to be trapped in a cave in northern Thailand. Police said that local authorities, police and rescue workers were working with divers to find the 12 boys, aged 11-15, and their coach, who are believed to have entered the Tham Luang Nang Non cave in Chiang Rai province late Saturday afternoon. The group were apparently trapped when a heavy rainstorm flooded a stream at the cave's entrance. Police Col. Komsan Saardluan said parts of the cave, which is an estimated 6-8 kilometers (4-5 miles) long, get flooded to a height of as much as 5 meters (16.5 feet) during the rainy season, which runs from June through October, AP reported.
