Presidents of Sudan and South Sudan met

The presidents of Sudan and South Sudan met in the Ethiopian capital on Saturday for the first time since the two countries went to battle over the Heglig oil field in April.

Their negotiators have made 'slow and uneven' progress in peace talks since the April crisis, said the African Union Commission in a report released the same day.

After years of conflict between the largely Muslim north and the mostly Christian south, a 2005 peace accord paved the way for the independence of South Sudan in 2011.

The two countries face the threat of sanctions from the United Nations Security Council unless they resolve differences over oil revenues and border demarcation by an August 2 deadline.
