Earlier on Friday Nepalese rescuers had only been able to find three bodies near the wreckage of a Camp Pendleton-based U.S. Marine helicopter that disappeared this week during a relief mission in the earthquake-hit Himalayan nation, and officials said it was unlikely there would be any survivors from the crash.
"The wreckage of the helicopter was found in pieces, and there are no chances of any survivors," Nepal's defense secretary, Iswori Poudyal said. He did not give the nationalities of the three victims, only saying their remains were charred.
The helicopter was carrying six Marines and two Nepalese army soldiers. Four Marines have been identified as, Sergeant Eric Seaman, Lcl. Jacob Hug, Captain Chris Norgren and Dustin Kukasiewicz.
A separate team sent by the U.S. Marines said they identified the wreckage as the missing helicopter, the UH-1 "Huey."
Lt. Gen. John Wissler, commander of the Marine-led joint task force, told reporters in Kathmandu that his team could not immediately identify the cause of the crash or identify the bodies found.
"It was very severe crash, and based on what we saw in the condition of the aircraft, we believe there were no survivors," he said.
He said extreme weather and difficult terrain hampered his team's efforts to work at the crash site.
"Due to the extremely difficult terrain of the site of the mishap, below-freezing temperatures and violent winds and thunderstorms, I made the decision to cease the recovery efforts for this evening," he said. "We cannot afford to put U.S. or Nepalese service members at any further risk."
Family members of those on board had remained hopeful for some good news despite reports of no survivors.
Family members of Captain Chris Norgren said he went down doing what he loved. "He was going to do what he needed to do to help them. He was going to give them the shirt off his back if that's what they needed. That's what he was doing. He was serving the families," they said.
The recovery mission will resume at first light Saturday.
Speaking in Washington, President Barack Obama expressed condolences to the families of all the victims and said the Marines "represent a truth that guides our work around the world: When our friends are in need, America helps."
The wreckage was found about 24 kilometers (15 miles) from the town of Charikot, near where the aircraft went missing on Tuesday while delivering humanitarian aid to villages hit by two deadly earthquakes, according to the U.S. military joint task force in Okinawa, Japan.
The area is near Gothali village in the district of Dolakha, about 80 kilometers (50 miles) northeast of Nepal's capital, Kathmandu.
The discovery of the wreckage, first spotted by Nepalese ground troops and two army helicopters Friday, followed days of intense search involving U.S. and Nepalese aircraft and even U.S. satellites.
The U.S. relief mission was deployed soon after a magnitude-7.8 quake hit April 25, killing more than 8,200 people. It was followed by another magnitude-7.3 quake on Tuesday that killed 117 people and injured 2,800.
The helicopter had been delivering rice and tarps in Charikot, the area worst hit by Tuesday's quake. It had dropped off supplies in one location and was en route to a second site when contact was lost.
U.S. military officials said earlier this week that an Indian helicopter in the air nearby had heard radio chatter from the Huey aircraft about a possible fuel problem.
A total of 300 U.S. military personnel have been supporting the aid mission in Nepal, which includes three Hueys, four Marine MV-22B Ospreys, two KC-130 Hercules and four Air Force C-17 Globemaster heavy-lift aircraft.
The Huey helicopter that crashed was from Marine Light Attack Helicopter squadron 469 based at Camp Pendleton, California.
Also Friday, the 193-member U.N. General Assembly called for urgent assistance to help earthquake survivors and to rebuild the impoverished Himalayan nation, urging the international community to support the U.N. appeal for $415 million for essential needs over the next three months.
Secretary-General Ban Ki-moon told the assembly that it is urgent to get aid to all those in need before the monsoon season starts in June.
