A search is underway for eight climbers missing for a week on an expedition in the Indian Himalayas.
The group, including four Britons, two Americans and an Australian, was atttempting to scale Nanda Devi East, one of the highest peaks in India at just over 7400m tall.
A group of 12 set out, but 12 days later only four returned to base camp.
Heavy rains and snowfall are hampering the search, a local official told news agency AFP.
"We have activated resources to trace the climbers after they failed to return to the base camp, but bad weather is hindering the operation," said Vijay Kumar Jogdande.
The group began climing just over two weeks ago, posing for a photo that was posted to expedition leader Martin Moran's Facebook page.
"We are in contact with the Indian authorities following reports that a number of British nationals are missing in the Indian Himalayas," a spokesperson for the British Foreign and Commonwealth Office told BBC News.
"We will do all we can to assist any British people who need our help."
The disappearance comes amid numerous reports of overcrowding and traffic jams atop Mt Everest, to the southeast in Nepal, resulting in several deaths.
