Moves are underway to evacuate Swiss tourists stranded in Thailand, where anti-government protesters continue to block Bangkok's international airport.
The travel insurance company, Elvia, said it would send a charter plane to U-Tapao, southeast of Bangkok, to pick up about 160 Swiss citizens.
However, Elvia said the aircraft does not have enough seats for all the stranded Swiss tourists and recommended they use an airport in the north of Thailand.
About 20 Swiss citizens were able to leave the country from the island of Phuket earlier this week.
The Swiss foreign ministry is advising citizens not to travel to Thailand.
Tens of thousands of tourists from across the world have been grounded in southeast Asia since members of the People's Alliance for Democracy movement invaded Bangkok airport four days ago crippling the tourism industry during the peak end-of-year season.
