All 44 people aboard a domestic flight in Laos were killed when the plane crashed in the south of the country, officials in neighbouring Thailand say.
The Lao Airlines plane came down in the Mekong River.
The aircraft crashed in bad weather just before it was due to land at Pakse airport, an airline official quoted by the Bangkok Post said.
The plane was on a flight from the Lao capital Vientiane when it crashed at about 16:00 local time (09:00 GMT).
Thai Foreign Ministry spokesman Sek Wannamethee said there were 39 passengers and five crew aboard the plane, citing information from the Thai Embassy in Vientiane.
He said five Thais were among the dead.
