After a three-day search, the remains of a U.S. military helicopter delivering aid in Nepal was found in shambles on a high mountain on Friday.

Army officials say the chopper was spotted near the village of Ghorthali at an altitude of 11,200 ft, reports Reuters. The helicopter crashed on Tuesday as it was distributing humanitarian relief to the survivors of a massive earthquake that struck Nepal last month. All eight passengers on board were presumed dead, said U.S. officials.

"Today at approximately 3:00 p.m. Japanese Standard Time a Nepalese search team identified possible wreckage of a downed aircraft approximately eight miles north of Charikot, Nepal," read a press release issued on Friday by the Department of Defense.

"Joint Task Force 505 dispatched a team of pararescuemen and a combat rescue officer to assess the wreckage. At approximately 5:05 p.m. Japanese Standard Time the team confirmed that the wreckage was that of the missing helicopter."

The wreckage from the missing Marines UH-1Y Huey helicopter was discovered by a U.S. search team. At the time of the crash, six Marines and two Nepali soldiers were on board.

"It was a very severe crash. We believe there were no survivors," said John Wissler, lieutenant general of the U.S. Marines.

Before the crash, the crew sent in a radio message reporting that the aircraft was experiencing a fuel problem.

"It was found on a steep slope," Maj. Gen. Binoj Basnet said.

U.S. Defense Secretary Ash Carter also released a statement, mourning the U.S. Marines who were onboard.

"This tragedy is a reminder of the vital but dangerous role that American servicemembers play in delivering humanitarian assistance and disaster relief," Carter said in a statement.

Nepal's Defense secretary Ishwori Prasad Paudyal added that the Huey, which is an iconic helicopter that was used in the Vietnam War era, was completely destroyed.

"As the helicopter has broken into pieces and totally crashed there is no chance of any survivors," said Paudyal.
