Tarakan, Indonesia — Rescuers flew to the jungles of Borneo island to retrieve the bodies of 13 people killed Saturday when an Indonesian army helicopter crashed and burst into flames.
Six others were injured in the crash, and were taken to a hospital to be treated for burns.
The helicopter was carrying construction workers to build a military outpost, but smashed into a cliff as it tried to land at the remote site near the border with Malaysia.
Eight of the fatalities were civilian construction workers and five were military crew members, according to reports.
Rescuers quickly found 11 of the 13 bodies inside the helicopter, which was a charred wreck, and put them in body bags.
A military spokesman told the media they believe all the bodies will be evacuated today from a cliffside in Malinau district in North Kalimantan province.
President Susilo Bambang Yudhoyono expressed his “deep sorrow” over the deaths.
Once all the bodies have been evacuated, an investigation will begin into the cause of the crash.
Military officials said they suspect it was a combination of bad weather and a malfunction of the back rotor blades, which spun out of control just prior to the crash.
