Officials in Nepal said five missing mountain climbers were likely killed by an avalanche on Mount Kanchenjunga earlier this week, UPI reported. The Nepal tourism ministry said the group went missing while descending the mountain and included climbers from Nepal, Hungary and South Korea. "All our efforts to trace them have failed," Mingma Sherpa, the organizer of the expedition, said. "The weather is bad and we've run out of resources to recover their bodies." Kanchenjunga is the third-highest mountain in the world at 28,169 feet. It is considered to be a technically challenging climb complicated by frequent blizzards and avalanches.
