ECU, I don't contest the tribal aspect, but please consider the following.
"The involvement of the churches, however, went far beyond the passive use of church buildings as death chambers. In some communities, clergy, catechists, and other church employees used their knowledge of the local population to identify Tutsi for elimination. In other cases, church personnel actively participated in the killing. The International War Crimes Tribunal for Rwanda convicted Elizaphan Ntakirutimana , a pastor in the Seventh-Day Adventist Church, for encouraging Tutsi to assemble at his church in Kibuye Prefecture, then leading to the church a convoy of soldiers and civilian militia, who slaughtered some 8,000 Tutsi.7 In April 1998, a Rwandan court condemned to death two Catholic priests, Jean-François Kayiranga and Eduoard Nkurikiye , for luring people to Nyange parish, where soldiers and militia subsequently massacred them, then bringing in a bulldozer to demolish the church and bury alive any survivors. Prosecutors in Rwanda have accused Father Wenceslas Munyeshyaka , the curé of Sainte Famille parish in Kigali, of turning over to death squads Tutsi who had sought refuge in his church. Survivors report that Munyeshyaka wore a flack jacket and carried a pistol and that he helped to select out sympathizers of the Rwandan Patriotic Front to be killed. According to some witnesses, he offered protection to women and girls who would sleep with him and turned over to death squads those who refused his advances."
