India, Aug. 1 -- Renowned Nepalese mountaineer Nirmal Purja, known widely as Nimsdai, is among 10 climbers who went missing on Broad Peak after an avalanche struck the mountain in Pakistan-occupied Kashmir (PoK) on Thursday.

Rescuers have recovered four bodies so far, with three flown to a hospital, as poor weather hampered search operations. Purja, who was leading the group, remains missing.
