Yangon, Myanmar - A rescue helicopter from Thailand has lost contact with ground control during a search for two climbers who scaled Southeast Asia's highest peak a month ago, officials said Sunday.
The helicopter was carrying three people, including a Thai pilot.
According to Htoo Foundation, the chopper left Putao airport in Myanmar's northern Kachin state on Saturday to drop food for a team searching for two Myanmar climbers missing since August 31. The foundation is leading the search effort for the climbers.
An eight-member team set out to climb the 5 881-meter (19 300-foot) Hkakabo Razi mountain last month, but only two went up the final stretch due to the narrow nature of the summit, reaching the ice-capped mountaintop on August 31.
The men reported before making their descent that their radio battery was weak. They were supposed to reconnect with their colleagues at base camp on September 9, but did not show up.
The search for the climbers involved helicopters from Thailand, the US and China, as well as other mountaineers.
