KATMANDU, Nepal (AP) — Nepalese authorities say they are meeting with Sherpa mountain guides in an attempt to avert a climbing strike after the deadliest avalanche ever recorded on Mount Everest.

Sherpas have threatened to boycott the climbing season after an avalanche ripped through the mountain Friday, killing at least 13 Sherpa guides. Three remain missing and are presumed dead. The guides’ demands include more insurance money and more financial aid for the families of the victims.

A Sherpa boycott could critically disrupt the Everest climbing season, which is key to the livelihood of thousands of Nepali guides and porters.

Maddhu Sudan Burlakoti, head of Nepal’s mountaineering department, said all the demands would be discussed and a recommendation would be made to the government later Tuesday.
