The reasons for establishing a second mission in Burundi, following directly on the ONUB missions, was the ceasefire agreement reached between the new CNDD-FDD government and the last remaining rebel group Palipehutu-FNL. This ceasefire agreement was signed on 7 September 2006 in Dar es Salaam, Tanzania, after mediation by South Africa in talks that began in May. Among the key points in the agreement were a complete cessation of hostilities, temporary immunity for FNL fighters and the demobilization of these troops and their subsequent integration into the armed forces of Burundi, in line with earlier peace agreements in this conflict that all stipulated power-sharing arrangements in the security sector.
