Input: Consider Input: Sentence 1: [Episcopal News Service]  Several parishes and villages in Sudan's Episcopal Diocese of Mundri have fallen victim to a fresh wave of attacks by the Lord's Resistance Army, a Ugandan rebel organization whose soldiers are prolonging a two-decades-long terrorist campaign gruesomely marked by widespread massacres and child abductions. At least four people have been confirmed dead and insecurity in the region is forcing residents to flee the villages of Tore Wandi, Moba, Bangolo, Ledinwa and Garia for the relative safety of Mundri. One of the slain is Wilson, a lay reader at a parish in Moba, wrote the Rt. Rev. Bismark Monday, bishop of Mundri, in a January 15 email to church partners. Monday explained that one of Wilson's sons and grandsons -- both about 10 years old -- were abducted. Sentence 2: The Lord's Resistance Army is a rebel organization.
