Rescuers are searching for 12 members of a youth football team thought to be trapped in a cave in northern Thailand.
Authorities believe the boys, aged between 11 and 16, and their coach entered the Tham Luang Nang Non cave in Chiang Rai province on Saturday.
They were apparently trapped when heavy rain flooded a stream at the cave entrance, but a local official said he believed they were still alive.
The cave is a tourist attraction which runs for many kilometres underground.
According to the Bangkok Post newspaper, visitors must cross a small stream to enter Tham Luang Nang Non, making it inaccessible if the stream floods.
Police Colonel Komsan Saardluan told AP news agency that the cave can flood up to 5m (16ft) during Thailand’s rainy season, which runs from June to October.
