Four Tibetan monks, Nyida, Kelsang, Nesang and Choeje, all from Goman Monastery in Ngaba, have been held in detention since September 11 for launching a public protest against the construction of a housing project near their monastery, reports Radio Free Asia. Shakya, a fifth monk, was also taken into custody but released after two days. The protest concerned the Chinese authorities’ plan to build a housing estate nearby.
