South Sudan president agrees to talks with rebel leader to stem violence

South Sudan's President Salva Kiir has agreed to fly to Ethiopia for talks and to consider forming a transitional government in an attempt to end four months of fighting in the world's newest nation, U.S. Secretary of State John Kerry said Friday.

Kerry, who met the president in South Sudan's capital, Juba, said he hoped Kiir would be able to hold a face-to-face meeting with rebel leader Riek Machar as early as next week to settle a conflict that has already killed thousands.

The top U.S. diplomat did not spell out what form a transitional government might take or go into any details of what it might mean for Kiir's continued leadership.

Kerry's meeting came a day after he warned that the increasingly ethnic violence could descend into genocide and said he expected the rapid deployment of more peacekeepers.

On Friday, he said Kiir had committed in their meeting to "to take forceful steps in order to begin to move to end the violence and implement the cessation of hostilities agreement and to begin to engage on a discussion with respect to a transition government."

Delegations from both sides have been meeting in Ethiopia, but their discussions have failed to advance since the Jan. 23 signing of a cease-fire that never took hold.

"I just spoke a couple of minutes ago to the prime minister of Ethiopia to convey to him President Kiir's willingness to [travel to] Addis Ababa, sometime early next week, hopefully in order to engage in a discussion ... with Machar," Kerry told reporters.

More than 1 million people have fled their homes since fighting erupted in December between troops backing Kiir and soldiers loyal to Machar, his sacked deputy.

The violence quickly spread to areas including the oil-producing north, often along ethnic lines between Kiir's Dinka people and Machar's Nuer.

Oil output, the nation's economic lifeline, has been cut by a third to about 160,000 barrels per day since fighting began.

International fears of a descent into genocide grew after the United Nations said rebels massacred hundreds of civilians in the northern oil town of Bentiu last month.

Days later, residents of Bor, a predominantly Dinka town, attacked a U.N. base where Nuer were sheltering.

Kerry said he hoped an initial deployment of about 2,500 U.N.-mandated troops could be on the ground within the next few weeks, to bolster some 7,000 U.N. peacekeepers already there.

Western diplomats have said U.N. forces need a tougher mandate than the one under which the existing U.N. Mission in South Sudan (UNMISS) operates so they can act more assertively to halt violence and protect civilians.

South Sudan won its independence from Sudan in 2011 under a peace deal to end decades of conflict. The U.S. and South Sudan's neighbors played a central role in that process and have been scrambling to stem the latest violence.

Concerns about continued violence, rampant corruption and the failure to build political institutions have eroded much of the political goodwill in Washington toward the new country's leadership.
