Among those missing on the Yalung Ri Himal mountain — which rises to 5,630 metres (18,470 feet) in the Dolakha district northeast of Kathmandu — were five foreign nationals, police official Gyan Kumar Mahato told Reuters.
The nationalities of the deceased and the missing climbers were not immediately known.
Four injured climbers were evacuated to a nearby village, while a search operation for the missing, including a helicopter mission, was underway, Mahato said.
“We have also dispatched ground search-and-rescue teams from the army and police and are awaiting developments,” he added.
Yalung Ri is located in the Rolwaling Valley of northeastern Nepal, where climbers encounter a challenging mix of rock, ice, and snow.
