Seven climbers set out on Friday to climb the mountain, which has a peak elevation of 5,642 meters above sea level. The next day, the weather deteriorated and the group got off the trail.
One of the climbers managed to get down and raised the alarm that two people had fallen ill and died at an altitude of around 5,100 meters.
"Rescue personnel found one more surviving climber and three more bodies," the local prosecutor said.
