Many of the rebel groups sowing unrest originate from other countries in the region, including Burundi, Uganda and Rwanda. A regional conflict from 1998-2003 resulted in millions of deaths as armed groups preyed on the local population and exploited the regions vast reserves of gold, tin and diamonds. A rebel group called Allied Democratic Forces (ADF), a Ugandan group targeted by the Congolese army and U.N. peacekeepers has been operating in the Nord-Kiku region. Last year, Congolese troops and U.N. peacekeepers launched a major offensive against the ADF, which is accused of widespread rights abuses including murder, rape and use of child soldiers. It funds its activities by trafficking timber and gold.
