(BBC) -Six Western tourists and two Thai guides have died after being swept away by flash floods in Thailand while exploring a cave, police have said.
The group were trekking through the Khao Sok national park, in Surat Thani province, when the cave flooded.
The dead have not been officially identified, but reports say a British man, four Swiss nationals and a German boy were among them.
One person survived and unofficial reports say she was 17 and British.
The UK Foreign Office confirmed that one Briton had died and one had survived, but would give no further details.
According to the Thai newspaper the Bangkok Post, the seven tourists and their Thai guides had travelled by boat from Ratchapraphra dam to the cave on Saturday.
The area inside the cave was flooded following a heavy downpour, which began about an hour before the party of tourists began their journey, it said.
