In 2004 Chad brokered negotiations in N'Djamena, leading to the April 8 Humanitarian Ceasefire Agreement between the Sudanese government, the JEM, and the SLA. However, the conflict continued despite the ceasefire, and the African Union (AU) formed a Ceasefire Commission (CFC) to monitor its observance. In August 2004, the African Union sent 150 Rwandan troops in to protect the ceasefire monitors. It, however, soon became apparent that 150 troops would not be enough, so they were joined by 150 Nigerian troops.
