Severe discrimination and persecution of Protestants, the ethnic minorities, is everyday life in Vietnam. Church service and private worship assemblies are prohibited. Montagnards , a collective term for all mountain peoples in Vietnam , have been forced to renounce from the Christian religion. Regular interrogation, arbitrary detention and the strong presence of special police units, create an atmosphere of fear and terror in the mountain villages. While interrogation, victims have been forced to stand on one leg for a long time and were abused respectively tortured. Hundreds of Montagnards have been convicted to prison terms up to 13 years for participating in peaceful protests and religious assemblies.
