NEPAL-EVEREST-MOUNTAINEERING-AVALANCHE

A young Nepalese boy holds a candle in memory of the 16 Nepalese Sherpa guides killed in an avalanche on Mount Everest in Katmandu on April 30, 2014. An unprecedented shutdown of Mount Everest after the worst ever accident on the world's highest peak has left grieving Nepalese sherpa guides and their families fearing for their livelihoods. The avalanche on April 18 that tore through a group of sherpas -- who were hauling gear up the mountain for their foreign clients before dawn -- left 16 people dead and three others seriously wounded.
