Pakistan authorities have confirmed the death of the three mountaineers who went missing while attempting to climb the world's second-highest peak.

The search operation has been called off and the death has been announced.

Pakistani climber Ali Sadpara, Iceland's John Sunori, and Chile's Juan Pablo Mohar were pronounced dead. Sadpara's son Sajid Sadpara was the last person to see them on February 5 at an altitude of more than 8,000 meters near the K2 summit. The campaigners were forced to return leaving the campaign unfinished due to malfunctioning of the oxygen regulator. 

Ali and Sajid participated in the campaign as high altitude porters.

At a press conference on Thursday Sajid announced the death of his father and two other climbers.

Sajid said, " K2 has taken my father into his arms forever."
