At least six mountaineers have been rescued from Mount Everest in Nepal after an avalanche struck their 6,100 metre base camp, officials say.
Weather on Everest can change fast at this time of the year
A helicopter safely took American and Canadian climbers - along with a Nepalese guide - to Kathmandu where some are being treated for injuries.
Another injured climber, identified only as being a Polish national, was reported not to have been evacuated.
The climbers were stranded after an avalanche hit their camp on Thursday.
The Chief Executive of the Himalayan Rescue Association, Prakash Adhikary, told the BBC that the helicopter returned to Kathmandu Saturday afternoon.
Officials said that the avalanche struck their Everest base camp at the height of 6,100 metres on Wednesday.
Officials say most of the climbers escaped unhurt, but some received minor injuries. Their Sherpa trekking guide reportedly suffered back injuries.
Mr Adhikary said the rescue helicopter could not be sent to the base camp over the last two days due to bad weather.
