UPDATE: Multiple reports indicate there were six Marines and two members of the Nepalese Army on board the missing Huey. ABC News reports a potential fuel problem may have caused the chopper to set down and that "officials are hopeful that the aircraft is simply missing because there has been no smoke or other signs of a crash."
The Associated Press is reporting that a Huey helicopter from the United States Marine Corps is missing in Nepal, where it was taking part in disaster relief efforts.
The helo, officially known as a UH-1 Iroquois, is part of Marine Light Attack Helicopter Squadron 469, and was operating near Charikot in the northeast of the mountainous country. Initial reports indicated that only two traditional helicopters were part of the US relief efforts, alongside four tilt-rotor MV-22 Ospreys.
US forces have been flying in Nepal since a devastating magnitude-7.8 earthquake hit late last month, killing thousands of people. The country was rocked again today by a magnitude-7.3 aftershock, although it's unclear if it had anything to do with the missing Huey.
According to the AP, US officials refused to comment when asked how many people were onboard the chopper, although they did admit the situation was under investigation.
