South Sudan's president says he is struggling with the idea of sharing power with rebels led by a former vice president who is likely to return to that post if a unity government is established.
President Salva Kiir's office said in a statement released Friday that: "We struggle with the notion that power can be achieved through violence."
The statement also said that although Vice President James Wani Igga is a trusted member of the government, he may lose his role under the terms of a peace deal still being negotiated.
South Sudan has seen sporadic fighting since December 2013 as government forces try to put down a rebellion led by former Vice President Riek Machar.
Peace talks between the warring factions are expected to resume later this month.
