Talks on peace process in South Sudan ended Monday without a complete peace deal reached between rival parties.

According to the regional block IGAD's mediators, South Sudan government required two weeks before signing the peace deal that was accepted by the South Sudanese rebels.

Under the IGAD's mediation, the agreement was signed by representatives of the SPLM/SPLA in opposition and former detainees of South Sudan as well as by other stakeholders towards ending the more than 20 months conflict in the world's youngest nation.

The government delegation led by South Sudan President Salva Kiir will make consultations with constituencies to come back in two weeks time to complete the agreement.

In his remarks on the occasion, Ethiopia's Prime Minister Hailemariam Desalegn, who is also Chairperson of IGAD, said it was an important one step forward into the political deadlock of the last 20 months.

"I would also like to take this opportunity to commend SPLM/SPLA in opposition and other political leaders to sign the agreement to give peace chance after a very long time...and often lengthy negotiation processes," Desalegn said.

He also commended Kiir for initialing on the peace document and giving a peace a chance.
