“There is a growing fear among the South Sudanese Christians, so they remain indoors in order to avoid being arrested.” That is how one church leader described the atmosphere in Khartoum after five South Sudanese Christians were arrested during a funeral prayer gathering on Aug. 16. What was meant to be a quiet moment of mourning in El Haj Yousif, a neighborhood in North Khartoum, quickly turned into a scene of fear. Among those taken was Pastor Peter Perpeny, a well-known leader with the Presbyterian Church of Sudan.
