The Nepal government has been unable to recover the three missing Sherpas three days after the fatal accident at the world's highest peak.

The three missing are identified as Pemba Tenji Sherpa, Aash Bahadur Gurung and Tenzing Chhotar Sherpa.

Since one of the deadliest avalanche hit Khubuche area near Camp 1 of Mount Qomolangma, also known as Everest, on Friday at around 5:30 a.m. local time, 13 have been confirmed dead.

The government had dug out 12 dead bodies of the Sherpas who had been swept away by the avalanche on Friday after it recovered one more body on Sunday afternoon.

All the deceased are local Sherpa guides who were making technical preparations for the climbing season beginning next week when they were hit by avalanche.

Stakeholders and family relatives of the missing Sherpas criticized the laxity of the Nepal government in its search and rescue operation.

Nepal's mountaineering entrepreneur and summiteer of 14 mountains above 8,000 meters, Mingma Sherpa on Sunday warned there would be no Sherpa involved in mountaineering support activities in the next 20 years if their social security issues were not addressed.

However, the government has been blaming the extreme weather conditions at the accident site for the delay in ascertaining whereabouts of the missing ill-fated guides.

"Despite our every effort, the continuous snowfall has been hindering the search operation," Madhusudan Burlakoti, joint secretary at Nepal's Tourism Ministry told Xinhua by phone.

He also said the body of the one Sherpa who was lately recovered will be soon handed over to the his family members.

"Rescue operation is underway. But the avalanche-hit site should be traced first as there was a heavy snowfall in the area yesterday night," added Burlakoti.

According to Nepal's Tourism Ministry, rescuers are currently holding meeting with experts and seasoned Sherpas, who are acquainted with the treacherous areas in the world's highest mountain, to prepare a strategy for effective rescue operation.
