National Movement for Reform and Development
The National Movement for Reform and Development (NMRD) is a Sudanese rebel group based in the region of Darfur. The group was formed when it broke away from the Justice and Equality Movement in 2004. The NMRD came into existence because its founding members felt that JEM focused too much on the political rather than the social and economic needs of the Fur people. JEM merged with the Alliance of Revolutionary Forces of West Sudan on January 20, 2006.
The political leader of NMRD is Khalil Abdallah.
On July 20, 2005, NMRD and Sudanese government representatives, led by Sharif Omar Badur, met in Al Fasher in northern Darfur to discuss ways of furthering cooperation in a United Nations and African Union monitored meeting. On July 23, 2005, NMRD signed a ceasefire agreement with the Sudanese government, agreeing to a mutual exchange of prisoners of war and allowing aid groups to deliver relief to local citizens. 
Battle of Arm Yakui
On January 28, 2006, NMRD attacked a Sudanese military base in Arm Yakui in western Darfur, killing 78 soldiers and taking 17 prisoners . The Sudan People's Armed Forces killed two, and injured five rebels, saying the attack "came suddenly from inside Chadian territory, and we returned fire with the same force using artillery."
The NMRD operates along the Chad-Sudan border.
"We don't understand why they are doing this. We have no problem with Mahamat Nour."
Nour denied UFDC involvement in the battle, "Our forces were nearby but they did not participate in the attack."
