Everest's 'deadliest day ever': Up to 18 climbers and sherpas feared dead, including Google executive, in avalanches caused by huge earthquake that killed at least 2,000 people across Himalayas

Mount Everest suffered its deadliest day in history yesterday after a huge earthquake that killed hundreds across the Himalaya caused avalanches that also claimed the lives of at least 17 climbers, including a 33-year-old Google executive. An avalanche triggered by a 7.8 magnitude earthquake in Nepal slammed into a section of the mountaineering base camp, where hundreds were preparing to make their summit attempts. Google executive Dan Fredinburg, inset, who used to date One Tree Hill actress Sophia Bush, was the first confirmed fatality on the mountain. Rescue efforts, pictured left and centre, are being hindered by aftershocks which continue to rock the country.
