The last survivor of the deadliest mountaineering disaster ever to hit the world's second-highest peak was rescued by helicopter Wednesday, nearly five days after the tragedy, a Pakistani army spokesman said. Italian climber Marco Confortola and three members of his support team were taken from a K2 base camp and were on their way to a nearby town, spokesman Maj. Farooq Feroz said. As many as 30 mountaineers began their ascent of K2 on Friday. An avalanche swept some climbers away and left others stranded in frigid conditions just below the 28,250-foot summit. In all, 11 people died: three South Koreans, two Nepalis, two Pakistanis and mountaineers from France, Ireland, Serbia and Norway, the Associated Press reported.
