North-South Sudanese talks on the status of the disputed Abyei region have hit a last-minute snag, just as a deal was to be signed resolving who will control the oil-rich border territory.
Northern and southern leaders are trying to settle outstanding issues ahead of Sudan's scheduled July 9 split. But the talks ground to a halt late Saturday, and negotiations remained stalled on Sunday — over a few final details.
Talks began a week ago, after an agreement in principle by Sudanese President Omar Hassan al-Bashir and southern leader Salva Kiir to demilitarize the oil-rich Abyei region and allow an Ethiopian peacekeeping force into the territory. But optimism has since abated, after the two leaders returned home and left more hard-line subordinates to work out details.
A second provision of the deal — a 72-hour cease-fire allowing for the delivery of critically needed supplies to civilians in southern Kordofan state — also is threatened by the diplomatic standoff.
The north occupied Abyei last month — one of several developments that have raised fears of renewed war in Sudan as the south becomes independent.
South Sudan voted to split from the north in a January referendum. The sides previously fought a 21-year civil war that ended in 2005.
