KATHMANDU: A climber from Bangladesh and another from South Korea have died on Mount Everest as hundreds flock to the world's highest peak during good weather, Nepalese tourism officials said Tuesday.
"Both men died while descending from the summit on Monday," an official with the tourism ministry told AFP from Everest Base Camp.
Sung Ho-Seo, 34, of South Korea was attempting the climb without supplementary oxygen and died on his way down the mountain.
Mohammed Hossain, 35, from Bangladesh, died in his tent a few hours after successfully climbing the summit.
"The exact cause of death is unknown, but altitude played a part," said the official, Gyanendra Shrestha, adding that the bodies would not be recovered until after the summit season ended so as not to interrupt other climbers.
Both men perished in the "death zone" -- above 8,000 metres, notorious for its difficult terrain and thin air.
Five other climbers have died on the 8,848-metre (29,029-foot) mountain this season.
Early in the season Mingmar Sherpa, 47, a member of an elite team known as the "icefall doctors" who set up climbing routes, plunged to his death.
DaRita Sherpa, 47, died from what is believed to have been cardiac arrest earlier this month. Commercial guide Lobsang Sherpa, 22, also plunged to his death. A 50-year-old Russian climber, Alex Bolotov, was found dead near the famed Khumbu Icefall crevasse on May 15.
Namgyal Sherpa, who had led expeditions to clear garbage and bodies from Everest, died May 16 while descending from his tenth successful summit.
Some 300 people have perished trying to reach the summit during the last six decades. The bodies of some of them remain on the mountain.
May is considered the best time for climbing in the Nepalese Himalayas because of mild weather and some 300 people have reached the top of Everest so far this year.
But a brawl that erupted last month between three European climbers and Nepalese guides on the mountain cast a shadow over this year's season, which marks the 60th anniversary of the maiden ascent by Tenzing Norgay and Edmund Hillary.
Pakistanis make history
Two young siblings achieved rare mountaineering glory for themselves by becoming the first Pakistani woman and only the third Pakistani man to set foot on the summit of Mount Everest in Nepal.
Through their feats, 21-year-old Samina Baig and her 29-year-old brother Mirza Ali ensured that their country’s flag fluttered on the world’s highest summit.
Mirza Ali and Samina can count themselves lucky as they will be remembered as the only Pakistanis to scale Everest on the 60th anniversary of the first conquest by Edmund Hillary on May 19, 1953.
Only two other Pakistani mountaineers, Nazir Sabir and Hassan Sadpara, have ever climbed the highest peak.
