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 while the North is considering it. It comes after both sides agreed to set up a demilitarized zone along their border to be jointly patrolled. Some 1.5 million people died in 22-year North-South civil war which ended in 2005.
