Oct. 7 (Radio Free Asia): Chinese authorities in Tibet have clamped down on protests against construction near a sacred mountain, holding protesters in jail and warning local Tibetans against further demonstrations. Beginning in September, Tibetans in Driru [in Chinese, Biru] county in the Nagchu Prefecture of the Tibet Autonomous Region (TAR) have challenged Chinese work crews trying to build a dam at Naglha Dzamba mountain, a traditional site of worship and offerings. Protesters believe that the Chinese are there not just to build a dam, but to begin mining in the area.
