Kuntal Karar was one of the two climbers who died.

Two Indian climbers died near the summit of Mount Kanchenjunga during an expedition on the world's third highest mountain in Nepal, their hiking company said on Thursday.

The climbers were identified as Biplab Baidya, 48, and 46-year-old Kuntal Kanrar, who died overnight at an altitude of about 8,000 metres (26,246 feet).

Pasang Sherpa of the Peak Promotion hiking company said Baidya, who climbed the 8,586 metre (28,169 feet) Kanchenjunga main summit on Wednesday, died due to altitude sickness on the way down. Kanrar died while trying to climb the peak, he said. Both were from Kolkata.

Hundreds of climbers are on different Himalayan peaks during the spring climbing season which ends this month.
