Police in Thailand say two foreign tourists, from China and Australia, have died in separate swimming accidents at the southern Thai resort island of Koh Samui.
Police Lt Col Apichart Jansamret said the two died today while swimming off Chaweng beach during high tide. Two other people were injured.
He said there were "no swimming" signs and red flags in place to warn tourists about the dangers of swimming there. Samui is a popular destination for foreign tourists in Thailand, which last year hosted a record-high 29 million visitors.
