In this photo provided to The Associated Press by Azim Afif, a helicopter prepares to leave base camp at Mount Everest to rescue people from the smaller camps 1 and 2 higher up the world's highest mountain. Afif and four other climbers from the University of Technology, Malaysia survived the avalanche that struck base camp after Saturday's powerful earthquake. At least 30 tents were flattened in the sprawling village of climbers, guides and porters that forms each spring during Nepal's most popular climbing season. The Nepal Mountaineering Association says at least 18 people died at base camp and 61 were injured. Numerous climbers were said to be stranded at higher elevations, though they were not believed to be in further danger.
