South Sudan's warring parties were due to start peace talks Thursday in the Ethiopian capital in a bid to end nearly three weeks of conflict that has left thousands dead in the world's newest nation.
Government and rebel negotiating teams arrived in Addis Ababa on Wednesday evening and while talks were expected Thursday, formal negotiations may not open for several days, Ethiopia's foreign minister said.
UN special envoy Hilde Johnson said in Juba it was "positive that they are sending delegations," underscoring the dire need for "reconciliation and healing" after the violence that has forced 200,000 people to flee their homes.
"We have seen terrible acts of violence in the past two weeks... and as we know, if there is no one held accountable, there is a major risk that the violence can continue," she added. Fighting erupted in South Sudan on December 15, when President Salva Kiir accused his former deputy Riek Machar of attempting a coup.
Machar has denied this, in turn accusing the president of conducting a violent purge of his opponents, and the fighting has spread across the country, with the rebels seizing several areas in the oil-rich north.
On Tuesday they recaptured Bor, the capital of Jonglei state just 200 kilometres (125 miles) north of the capital Juba. The government confirmed on Wednesday that it had lost control of Bor, which has changed hands three times in the past two weeks, as fighting reportedly continued in the area.
Thousands of people are feared dead, UN officials say, while close to 200,000 civilians have been forced to flee their homes -- many seeking refuge with badly overstretched UN peacekeepers.
The conflict has also been marked by an upsurge of ethnic violence pitting members of Kiir's Dinka tribe against Machar's Nuer community, and the UN Mission in South Sudan (UNMISS) said that "atrocities are continuing to occur" across the country. Addis Ababa (AFP)
