An Indian climber went missing while descending the "death zone" after scaling Mount Everest, officials said Sunday, following the death of two climbers over the past month.

Ravi Kumar, 26, was climbing down from the 8,850-meter-high (29,035 feet) summit and got separated from his guide near a place called Balcony on Saturday, Thupden Sherpa of Arun Treks and Expedition company that sponsored Kumar's team said in Kathmandu.

"Three Sherpa rescuers have been sent to search for Kumar," Thupden said, adding the climber had been out of contact.

A Tourism Department official, Gyanendra Shrestha, confirmed Kumar had not contacted anyone.

On April 30, a famed Swiss climber fell to his death near Mount Everest during preparations to climb the world's highest mountain, while an 85-year-old Nepalese man died at the base camp earlier this month while trying to set a record for the oldest climber.

Nepal has cleared 371 mountaineers to climb Mount Everest during the current season, which ends this month.
