This agreement marked the formal end of the Second Congo War. Three rebel groups supported by Uganda, the MLC, RCD-N and RCD-ML, signed a ceasefire, the Gbadolite Agreement, on December 31, 2002. This obliged them to immediately stop all fighting in the Isiro-Bafwasende-Beni-Watsa quadrangle and to accept United Nations military observers in the area. It also contained guarantees of the freedom of movement of the civilian population and humanitarian organizations from one area to another. This treaty was violated numerous times.
