In 2000, the Burundian President signed the treaty, as well as 13 of the 19 warring Hutu and Tutsi factions. Disagreements persisted over which group would preside over the nascent government, and when the ceasefire would begin. The spoilers of the peace talks were the hardliner Tutsi and Hutu groups who refused to sign the accord; as a result, violence intensified. Three years later at a summit of African leaders in Tanzania, the Burundian president and the main opposition Hutu group signed an accord to end the conflict; the signatory members were granted ministerial posts within the government. However, smaller militant Hutu groups – such as the Forces for National Liberation – remained active.
