Kathmandu: Eight people, six US Marines and two Nepalese soldiers died when their helicopter crashed in a mountainous region of earthquake-devastated Nepal, US Defence Secretary Ashton Carter said on Friday.
The UH-1Y Huey had been delivering aid when it disappeared on Tuesday, with the wreckage only found on Friday after a search mission involving helicopters and hundreds of American and Nepalese troops.
"Today our hearts are heavy with grief for the US Marines who perished when their helicopter went down in the mountains of Nepal earlier this week while providing aid to earthquake victims there," Carter said in a statement.
"We also join our Nepalese partners in mourning the loss of their service members who were onboard the helicopter at the time."
The US defence chief added: "Our mission continues in Nepal, and we remain dedicated to answering the call when disaster strikes, both in the Asia-Pacific and around the world."
John Wissler, the commander of the joint task force investigating the helicopter's disappearance earlier confirmed the wreckage of the helicopter had been found, describing the incident as a "severe crash".
He said he could not yet "positively identify the cause of the mishap", adding that recovery operations would resume on Saturday after being called off due to heavy thunderstorms.
The aircraft was spotted in a remote forest around 70 kilometres (40 miles) northeast of Kathmandu, according to Nepalese army official Major General Binoj Basnet.
Basnet told AFP that troops had reached the crash site on foot and two choppers, including a US military helicopter, had managed to land in the mountainous region after strong winds had kept them circling the wreckage.
Army helicopters and hundreds of US and Nepalese ground troops had been deployed to scour the mountainous terrain where the US chopper disappeared on the same day that a second major earthquake hit the country.
Before it went missing, there was "some chatter about a fuel problem" on the radio from the helicopter crew, Pentagon spokesman Colonel Steven Warren said on Tuesday.
Working for weeks
Relief teams from around the world have been working for weeks to provide water, food, shelter and medical assistance to Nepal after the first, 7.8-magnitude quake hit on April 25.
Nearly 8,500 people have now been confirmed dead in the disaster, which destroyed more than half a million homes and left huge numbers of people without shelter with just weeks to go until the monsoon rains.
The missing helicopter was among more than a dozen US military aircraft devoted to aid operations, including two other Huey choppers and four tilt-rotor Ospreys as well as cargo planes.
The United Nations has said it faces a "monumental challenge" to bring relief to victims, many of whom live in areas accessible only on foot or by helicopter.
Jamie McGoldrick, UN humanitarian coordinator for Nepal, on Friday warned of "more deaths" to come in quake-hit regions unless donors dramatically ramp up aid contributions, which currently stand at just 14 percent of the $423 million appeal launched on 29 April.
"If we don't act quickly, the implications will be severe," McGoldrick said in a statement.
"We can only expect misery, a crippling loss of dignity and the real potential for more deaths especially in the rural and remote areas."
The Nepalese government has said it was overwhelmed by the scale of the April 25 disaster, the deadliest earthquake to hit the country in more than 80 years.
The challenge was compounded by Tuesday's quake, which was centred in the remote eastern district of Dolakha and triggered multiple landslides.
The death toll from that quake has risen to 117, but a Dolakha government official said bodies were still being retrieved from under the debris on Friday.
"We have been struggling to reach certain places because of road blockages and disruptions to communications," assistant chief district officer Aaulakh Bahadur Ale told AFP by telephone.
"Over 200,000 people are homeless here, we are working to provide alternative accommodation for them."
