In May 1998, Jean-Bosco Ndayikengurukiye, Nyangoma's chief of staff, caused a schism by ousting the latter over leadership issues and losses suffered by the group during the First Congo War, the Nyangoma-led faction later taking a seat at the Arusha negotiations, while the Ndayikengurukiye's faction carried out its fight. In 2001, the CNDD– FDD consisted of about 25,000 rebels, but in September of that year Ndayikengurukiye was ousted by a faction led by Pierre Nkurunziza over the former's handling of negotiations with the government to join the transitional administration set up by in Arusha Accords. The Nkurunziza-led faction, consisting of 20,000 to 22,000 troops signed a ceasefire with the government in December 2002 but continued fighting. The faction led by Ndayikengurukiye became the lesser of the two with about 5,000 fighters. It also signed a ceasefire with the government in October 2002 to which it has roughly held.
