Addis Ababa - Mediators say South Sudan's warring parties have failed to reach a final deal following days of negotiations in Ethiopia.
Ethiopian Prime Minister Hailemariam Desalegn said in a statement on Friday that he regretted "the talks did not produce the necessary breakthrough".
South Sudanese President Salva Kiir and rebel leader Riek Machar had been given a 5 March deadline to finalise issues including power sharing, but mediators extended the talks until Friday in hopes the rivals could reach an agreement.
