Agreement Sought for Border Dispute The United Nations Security Council on Thursday called on Sudan and South Sudan to reach an agreement on the status of the disputed, oil-rich Abyei border region and extended the United Nations security force's mission there by six months. The Council demanded that Sudan withdraw all security forces from Abyei; South Sudan removed about 700 police officers last week. The Council also passed a resolution calling the situation a serious security threat and demanding the creation of a jointly administered Abyei police force.
