A white bull enters a cattle camp, near the town of Abyei October 30, 2013. Abyei officials welcomed a push by the African Union to involve the U.N. Security Council in helping plan a referendum to resolve a dispute in the remote border region.

The result of the vote in which 65,000 people had registered to take part in is expected on October 31.
