In Sudan, the UN initially sponsored UNMIS to enforce a ceasefire between the &lt;a href="Sudan%20People%27s%20Liberation%20Army/Movement"&gt;Sudan People's Liberation Army/Movement&lt;/a&gt; and the Sudanese government. Since then, rebel groups in Darfur have clashed with government-sponsored forces, resulting in UNAMID, the AU/UN Hybrid Operation in Darfur. Violence in Darfur, spilled over the border into Chad and the Central African Republic. In 2007, MINURCAT was deployed to minimize violence to civilians and prevent interference of aid distribution related to violence in Darfur.
