Instagram/Nirmal Purja9 Ten mountaineers, including Nirmal Purja, are feared missing in an avalanche on Pakistan’s Broad Peak. Authorities have received no communication from the crew atop the world’s 12th tallest mountain and have mobilized an all-out search-and-rescue mission. A high-altitude climber who led an expedition up Broad Peak last week told The Post Thursday he feared recent weather conditions could spell trouble. After the distressing ordeal and concerns about the equipment’s quality on the mountain, Fuller and his sherpa decided not to scale the remaining vertical gap.
