“It is most likely they died from carbon monoxide poisoning by using their stoves in the tent without proper ventilation,” US climber Alan Arnette, who blogs on Everest, said in a post.
Ten people have died so far in a series of accidents this climbing season – four more than mountaineering officials expect in a typical year.
Indian climber Ravi Kumar, American doctor Roland Yearwood, Slovak climber Vladimir Strba and Australian Francesco Enrico Marchetti all died over the weekend.
More than 5,000 climbers have scaled Mount Everest since it was first climbed by New Zealander Sir Edmund Hillary and Sherpa Tenzing Norgay in 1953, and nearly 300 have died trying.
