The United Nations mission in Chad and the Central African Republic, MINURCAT(United Nations Mission in the Central African Republic and Chad), was established in the United Nations Security Council Resolution 1778 on September 25, 2007, which would leave a multidimensional force in Chad and the Central African Republic (CAR) to help create security conductive to a voluntary and sustainable return of Refugees. The mission was created due to an estimated 230,000 refugees fleeing Darfur into eastern Chad and north-eastern CAR. Continued cross border assaults from Sudanese rebels have endangered refugees and local residents alike.
