KATHMANDU - Nepalese guides on Mount Everest said Tuesday they had decided to abandon this year's climbing season, to honour 16 colleagues killed in an avalanche last week.
The decision throws the plans of hundreds of foreign mountaineers into chaos, with many of them waiting in base camp after paying tens of thousands of dollars to scale the world's highest peak.
The sherpas perform essential tasks on the 8,848-metre (29,029-foot) mountain, carrying equipment and food as well as repairing ladders and fixing ropes to reduce risks for their clients.
"We had a long meeting this afternoon and we decided to stop our climbing this year to honour our fallen brothers. All sherpas are united in this," local guide Tulsi Gurung told AFP from base camp.
"Some guides have already left and others will take about a week to pack up everything and go," said Gurung, whose brother is among those missing after an avalanche last Friday killed 13 sherpas and left three missing and presumed dead.
Another guide, Pasang Sherpa, added: "Sixteen people have died on this mountain on the first day of our climb. How can we step on it now?"
The guides had threatened to cancel all climbing on Mount Everest and issued an ultimatum to the government, demanding higher compensation, an agreement to revise insurance payments and a welfare fund by next Monday.
The decision to abandon the season appeared to pre-empt the outcome of talks underway in Kathmandu. High-profile Western mountaineers headed to the capital Tuesday afternoon to seek a resolution to the crisis.
"They have decided that compensation is not the only issue, they feel like they have to close down Everest this year as a memorial to those who died," said Ed Marzec, an American climber who spoke to AFP from base camp.
"They also want to stage a protest next month in Kathmandu and they say they can't do that if they are on the mountain," he added.
Marzec, a retired lawyer who hoped to become the oldest American to conquer Everest at the age of 67, said the atmosphere at base camp was souring fast - with some climbers putting pressure on sherpas so they would stay on and help them summit.
