TOPSHOTS This photo taken on June 4, 2013 shows newly installed turbines at the Salkhit Mountain wind farm, 70 kilometres from Ulan Bator. The wind farm, which will be Mongolia's first, is due to open on June 20 and is part of the government's attempts to reduce air pollution that makes Ulan Bator the world's second most polluted city during the winter months.
