Ethiopia has offered to send peacekeepers to Sudan’s disputed border region of Abyei after its recent seizure by northern troops.
Analysts have feared the Abyei dispute could reignite the civil war between the north and South Sudan, which is due to become independent in July.
Officials say the south has accepted the offer; the north is considering it.
Sudan expert Alex De Waal, who is has been working on the African Union-mediated deal, told the BBC negotiations about how it would work were ongoing.
Some 1.5 million people died in the 22-year north-south civil war which ended in 2005.
Border force request
The UN Security Council condemned the occupation of Abyei and called for the immediate withdrawal of northern troops from the oil-producing region also claimed by the south.
But Sudan’s ambassador to the UN Daffa-Alla Elhag Ali Osman has said it will do so only when new political and security arrangements have been agreed.
Meanwhile, he said Sudan’s government wanted peacekeepers to leave its territory when South Sudan becomes independent in July.
