Disputes - international:
Tutsi, Hutu, other conflicting ethnic groups, associated political rebels, armed gangs, and various government forces continue fighting in the Great Lakes region, transcending the boundaries of Burundi, Democratic Republic of the Congo, Rwanda, and Uganda in an effort to gain control over populated and natural resource areas; government heads pledge to end conflict, but localized violence continues despite the presence of about 6,000 peacekeepers from the UN Operation in Burundi (ONUB) since 2004; although some 150,000 Burundian refugees have been repatriated, as of February 2005, Burundian refugees still reside in camps in western Tanzania as well as the Democratic Republic of the Congo
