A helicopter searching for eight climbers who went missing in the Indian Himalayas has spotted five bodies, Indian sources say.
Four Britons, two Americans, an Australian and an Indian made up the missing group who disappeared on India’s second highest-peak.
“They were on the same route as the climbers had taken,” a source told AFP, referring to the bodies seen.
The Nanda Devi mountain was believed to have been hit by multiple avalanches.
Authorities are trying to assess how to retrieve the bodies from such treacherous terrain where helicopters cannot land, says the BBC’s Yogita Limaya in Mumbai.
The climbers have not been heard from since 26 May, a day before an avalanche hit the 7,816-metre mountain.
Four other climbers who were part of the group ascending the peak were rescued on Sunday and have since then been assisting rescue efforts.
They had turned back early because of the harsh weather, and were the last ones in contact with the larger group.
Who are the missing?
The missing group was being led by experienced British mountain guide Martin Moran, whose Scotland-based company Moran Mountain has run numerous expeditions in the Indian Himalayas.
The rest of the group have been named as John McLaren, Rupert Whewell and University of York lecturer Dr Richard Payne from the UK; US nationals Anthony Sudekum and Ronald Beimel; Australian Ruth McCance and Indian guide Chetan Pandey.
“Some bodies were visible during the helicopter recce,” the military source told AFP.
“The chances of survival are very, very bleak at a height of 15-18,000 feet [4,570-5,500 metres] in such a cold climate. It is almost impossible they are alive.”
What about the survivors?
The four rescued climbers were named as Mark Thomas, 44, Ian Wade, 45, Kate Armstrong, 39, and Zachary Quain, 32.
They had been airlifted to safety after being spotted early on Sunday at Munsiyari base camp near Nanda Devi.
Information they provided after their rescue helped to narrow the search area to about 50 sq km (20 sq miles).
Nanda Devi is the world’s 23rd highest mountain and was first scaled in 1936.
Considered one of the toughest Himalayan peaks to climb, it attracts fewer climbers than other mountains in the region.
