Two Russian men have died while climbing in the Himalayas after suffering from the effects of altitude sickness, a news report said.
The first man, identified as 47-year-old Viktor Igolkin, passed away Tuesday at a camp on the Ama Dablam Mountain in Nepal, a local official said, The Himalayan Times reported Wednesday.
A second man, 63-year-old Pavel Ivanovsky, passed away Wednesday at the same camp, located 4,900 meters above sea level.
Reduced air pressure and lower oxygen levels at high altitudes are a common threat to climbers, causing headaches, dizziness and, in the most severe cases, death.
The two bodies have been sent to the Nepalese capital, Kathmandu, where doctors will carry out an autopsy to confirm the exact cause of death, Lenta.ru reported.
The deaths come just a few weeks after an avalanche killed 16 people on nearby Mount Everest in the single largest loss of life ever recorded on the mountain.
