Rescuers found the bodies of four climbers on Mount Everest, an expedition organiser said Wednesday, taking the season's death toll to 10 as experts warn cut-price mountaineering outfits are putting clients at risk. The bodies of the four climbers were found inside two tents at Camp Four, located at 8,000 metres (26,246 feet), overnight, Mingma Sherpa of the Seven Summit Treks group to which the sherpas belonged said in Kathmandu. The sherpas who discovered the bodies were on their way to retrieve the body of Vladimir Strba of Slovakia who died near the 8,850 metre summit on the weekend, along with three others including Australian Francesco Enrico Marchetti. British Everest expedition leader Tim Mosedale wrote in a recent Facebook post that the increasing number of climbers has led to more guides who are less-experienced:



Major causes of death on Everest include "exhaustion, exposure, frostbite, falls and altitude sickness," Reuters reported. This year a record 373 permits were issued to foreign climbers to summit Everest from the Nepal side, with another 136 granted permission to ascend from the north face in Tibet.
