KATMANDU, Nepal (AP) - The world's highest mountain has seen its deadliest-ever disaster today.
As Nepalese Sherpa guides worked to set up ropes for other climbers on Mount Everest, an avalanche swept down the climbing route. At least 12 of the guides were killed, and four others are missing. Several more were hurt.
An injured survivor told relatives that the path up the mountain was unstable just before the avalanche.
Hundreds of climbers, guides and support crews are at Everest's base camp. They've been preparing to climb to the summit when weather conditions will be at their most favorable early next month. They've been setting up camps at higher altitudes, and guides have been fixing routes and ropes on the slopes above.
