The Security Council on Monday extended the mandate of the U.N. peacekeeping force for Abyei, which is tasked with overseeing the demilitarization of an area contested by Sudan and South Sudan. In a unanimous vote, the 15-country council extended the U.N. Interim Security Force in Abyei (UNISFA) until the end of May 2014. The mission was established by the Security Council in June 2011.
