Watch: Moment climber is rescued from Everest ‘death zone’

Nepali guide Gelje Sherpa found a Malaysian climber shivering and clutching a rope in the area of Mount Everest called the "death zone", where temperatures can dip to -30C. He carried the climber down from 8,500m above sea level over the course of six hours, in what has been described as a “very rare” high-altitude rescue.
