JUBA: South Sudan's government and rebels agreed a ceasefire on Tuesday, mediators said, though there was no immediate confirmation from either side or sign of an end to ethnic fighting that has ravaged the world's youngest nation.
Less than two hours before the deal was announced, officials said militias loyal to ex Vice President Riek Machar were still fighting in Bor, the main town in the vast, underdeveloped Jonglei state and the site of an ethnic massacre in 1991.
"We will retake the part we lost very soon," Bor's mayor, Nhial Majak Nhial, told Reuters. A rebel spokesman in neighboring Unity state said the rebels had taken the town.
The IGAD group of East African countries said both sides had appointed teams to start negotiations.
"President Salva Kiir Mayardit and Dr. Riek Machar agree on a cessation of hostilities and appoint negotiators to develop a monitored and implemented ceasefire," it added, without saying when any ceasefire or talks might start.
Western and regional powers have pushed both sides to end the fighting that has already killed at least 1,000 people, cut South Sudan's oil output and raised fears of a full-blown civil war in the heart a fragile region.
The clashes erupted on December 15 with fighting among a group of soldiers in Juba. The violence quickly spread to half of the country's ten states, cleaving the nation along the ethnic faultline of Machar's Nuer group and Kiir's Dinkas.
Kiir accused his long-term political rival Machar, who he sacked in July, of starting the fighting in an effort to seize power.
Machar denied the charge, but took to the bush and acknowledged leading soldiers battling the government. There have been conflicting reports on whether Machar was in full control of the Nuer "White Army" militia fighting in Bor, though on Tuesday he told the BBC they were part of his forces.
The fighting has revived memories of the factionalism in the 1990s within the Sudan People's Liberation Movement – the group that fought Sudan's army in the north for two decades. Machar led a splinter faction and fighters loyal to him massacred Dinkas in Bor.
Both the government and the rebels earlier said they were sending teams to start talks in neighboring Ethiopia, though Machar at the time told the BBC he was not prepared to lay down weapons.
The U.S. special envoy to South Sudan, Donald Booth, said the commitment to send negotiators was an "important first step" towards a negotiated settlement.
