Leaders of two warring sides in South Sudan have agreed to yet another peace deal.

At least two previous peace deals fell through as fighting between rebels and government forces resumed shortly after negotiated settlements.

The deal agreed to early Saturday may hold more weight because of increasing threats by the U.N. Security Council and leaders of East African countries to impose economic and travel sanctions on South Sudanese leaders.

A statement from the regional body IGAD said that the warring parties commit to an unconditional, complete and immediate end to all hostilities.

Fighting broke out last December between rebels loyal to former Vice President Riek Machar and government troops backing President Salva Kiir. More than 1.7 million have fled their homes since then.
