The United Nations Mission in the Sudan (UNMIS) was established by the UN Security Council under Resolution 1590 of 24 March 2005, in response to the signing of the Comprehensive Peace Agreement between the government of the Sudan and the Sudan People's Liberation Movement on January 9, 2005 in Nairobi, Kenya. Its most well-known employee was journalist Lubna al-Hussein, who resigned in order to waive her immunity.
