Three climbers who went missing earlier this month while attempting to scale the world’s second-highest mountain, K2, should now be considered dead, Pakistani officials said Thursday. The announcement brings closure to a dramatic tragedy on one of the most dangerous mountains to climb in the world. K2 had never been scaled in winter until only last month when a Nepalese team reached the peak.

The three climbers — famous Pakistani mountaineer Ali Sadpara as well as Jon Snorri of Iceland and Juan Pablo Mohr of Chile — lost contact with their base camp while attempting their ascent of the 8,611-meter (28,250-foot) high K2, sometimes referred to as “killer mountain.”

Rest in Peace bravehearts. The World has lost skilled mountaineers.
