KATHMANDU - A 51-year-old Russian climber has been missing in Nepal’s Himalayas for two days, with bad weather hampering search efforts, a top local official said Thursday. The mountaineer was descending with his team on Tuesday after successfully summiting the 6,091-metre (19,983-foot) high Pisang peak in the Annapurna region.His three other team members only realised that he was missing when they arrived at base camp, Manang district chief Bhim Kanta Sharma told AFP. “The climber was reported missing on Tuesday evening and we have begun our search,” Sharma said, adding that it was unclear where on the mountain he was.
