About 20,000 troops and policemen from more than 30 countries are currently in Sudan's western region of Darfur as part of the African Union-United Nations mission, UNAMID.
A report by UN chief Ban Ki-moon and the Chairperson of the African Union Commission, Nkosazana Dlamini Zuma, recommends that UNAMID's mandate be extended by another year.
The report which was submitted to the Security Council cites the "limited progress" made to reach a viable solution to end the conflict in Darfur that has killed tens of thousands of civilians since 2003.
It recommended extending UNAMID's mandate -- which expires at the end of the month -- "for 12 months, until 30 June 2017."

The UN Security Council is expected to meet before the end of June to endorse or reject the recommendation.
Khartoum insists that unrest in Darfur has ended and has stepped up pressure for a complete exit of the international peacekeepers from the war-torn region, where they have been deployed since 2007.
"The report by the African Union and the United Nations consists incorrect information about the humanitarian and security situation in Darfur," it said.
Last month Sudan's Minister of State for Foreign Affairs, Kamal Ismail, said: "It's time to say goodbye to the UNAMID mission."
"This mission came to protect civilians, but now there is no danger to civilians, there is no conflict in Darfur," he added.
Violence erupted in Darfur when ethnic minority rebels rose against President Omar al-Bashir, accusing his Arab-dominated government of marginalising the region.
