In a daring operation at an altitude of 18,000 feet, Indo-Tibetan Border Police (ITBP) troopers on Thursday retrieved two bodies of West Bengal trekkers, who died in Himachal Pradesh's Pin Valley this week, and brought them on stretchers to the base camp, trudging 32 km.

The bodies were handed over to the civil administration in Kaza, some 320 km from here, Sub-Divisional Magistrate Mohan Dutt told the media.
