The United Nations Interim Security Force for Abyei (UNISFA) is a United Nations peacekeeping force in Abyei, which is contested between the Republic of Sudan and the Republic of South Sudan. UNISFA was approved on 27 June 2011 by the United Nations Security Council in United Nations Security Council Resolution 1990 after a flareup in the South Kordofan conflict earlier in June 2011. The Ethiopian Army is the largest contributor of personnel, and as of 2018, the only contributor of individual troops.
