Efforts for rescue a Polish man and a French woman stranded on Pakistan's second highest peak will begin on Saturday, authorities said.
Tomek Mackiewicz and Elisabeth Revol were attempting to ascend Nanga Parbat, known as Killer Mountain, when they got stuck at 7,400m (24,280 feet).
They used a satellite phone to call for help to descend the 8,120 meeters mountain.
Climbers with binoculars at the base camp spotted Ms Revol trying to climb down, while Mr Mackiewicz was crawling.
"They had spent one night outside the camp and the Polish mountaineer has got frostbite and snow blindness so he is not able to climb down," a local climber in contact with the base camp team told the AFP news agency.
Four members of a team of Polish climbers attempting the first winter summit of nearby K2, the world's second highest mountain, will assist in the rescue operation.
They will be transported by a Pakistani army helicopter and "brought from K2 to Nanga Parbat and then the operation will begin," Asghar Porik of Jasmine Tours told Reuters.
