Five army officers were killed when their military helicopter crashed in western Thailand, an official said Sunday, dpa reported.
The helicopter came down in mountainous terrain in Kaeng Krachen National Park near the Myanmar border in bad weather on Saturday, Lieutenant General Udomdej Sitabutr said.
The helicopter was on its way to pick up officials dispatched to the country's largest national park on July 11 to arrest suspected illegal loggers.
Soldiers had been sent to recover the bodies, the military said.
