10 persons have so far died on top of world highest mountain Everest.

Four climbers have been found dead inside a tent on Mount Everest, taking the death toll this season to 10.

The bodies were discovered by a rescue team sent to retrieve the body of a Slovak climber who died on the mountain on Sunday. All the fatalities have occurred in or near the so-called "death zone", where oxygen levels are extremely low.

Local media reported that the latest deaths were two foreign climbers and two Sherpa guides.

This season has also claimed the lives of an Australian, Francesco Marchetti; an Indian, Ravi Kumar, whose body was found on Monday; and 85-year-old Min Bahadur Sherchan, who died attempting to reclaim his title as the world's oldest person to reach the top.

World-renowned Swiss climber Ueli Steck also died during an acclimatisation climb at the end of April.
