"Search underway for 3 missing climbers on Mount Everest"

Three Sherpa climbers are missing after falling into a 160-foot deep crevasse on Mount Everest's Khumbu Icefall. The area is considered one of the most difficult and tricky sections of the climb to the peak. A rescue helicopter is trying to locate them while rescuers search on foot. The incident occurred as hundreds of foreign climbers and Nepalese guides and helpers attempt to scale the mountain during the main climbing season.
