The deal, reached on the sidelines of the annual U.N. General Assembly session, was a compromise by the African Union, which had hoped to turn over control for peacekeeping in Darfur to the United Nations after Sept.
30, when the mission's current mandate expires.
The U.N.
Security Council passed a resolution last month that would expand the mission from 7,000 to more than 20,000 troops and give it new authority to protect civilians.
But Sudan's government vehemently opposes the introduction of U.N.
forces in Darfur, where fighting between rebels and government-backed militias has left more than 200,000 people dead and 2.5 million displaced since 2003.
