BENI, DR Congo: Armed groups have killed seven civilians and three members of the security forces in eastern DR Congo, where a clinic was set ablaze, local sources said on Thursday (Friday in Manila). Two soldiers at Butembo, about 50 kilometers (30 miles) from Beni in North Kivu province, were killed by "Mai-mai militiamen," said Colonel Donat Mandonga, the chief administrative official in neighboring Lubero district. A policeman and four militiamen were also killed in the fighting, said Captain Anthony Mualushayi, the army's spokesman in the Beni region. The term "Mai-mai'' is widely used to describe armed groups claiming to represent communities in the region's many ethnic feuds. Separately, the Allied Democratic Forces (ADF) on Wednesday killed four women and three men as they worked in fields near the Ugandan border, Ricardo Rupande, a community organizer in Rwenzori, said. The ADF is a group that the self-described Islamic State group says is an affiliate. The ADF is the most violent of more than 120 armed groups that roam the eastern Democratic Republic of Congo, according to monitors.
