Some 22 people, mainly foreign tourists, are missing after their plane disappeared in south-west Cambodia, believed to have crashed. Passengers on board were mainly South Korean.
Rescue efforts are under way to find the passengers who were flying between two popular tourist destinations.
But the search efforts have been hampered by bad weather and a difficult terrain of dense forests in Kampot province, made muddy by heavy rains.
Hundreds of soldiers and police are taking part in the rescue effort in the area where witnesses reported seeing the plane come down.
The tourists were travelling on a new service which officials hoped would encourage visitors to spend longer in the country. Cambodia is particularly popular with South Koreans.
