South Sudan: 'Ethnic Killings' As Graves Found

Mass graves have been uncovered in South Sudan amid evidence of ethnic killings in the world's newest state.

Dozens of bodies were discovered at a site in South Sudan's oil rich Unity State, as the death toll from a week of fighting increases.

Violence has flared in a power struggle between President Salva Kiir, an ethnic Dinka, and his ex-deputy Riek Machar, an ethnic Nuer.

The bodies in the grave are thought to be among 75 Dinkas who have gone missing.

Meanwhile, a journalist in the capital, Juba, quoted witnesses as saying more than 200 people, mostly Nuers, had been shot by security forces.

The official total dead is 500, but the real figure is believed to be far higher, aid workers say.

Britain has sent a senior diplomat to South Sudan to assist efforts to restore peace, as the UN prepared to vote on boosting the size of its force.

Reports suggest that British nationals are among an estimated 3,000 foreigners trapped in the city of Bor, which was seized by rebels last week.

President Kiir said that government troops had now retaken control of the city.

UN spokeswoman Ravina Shamdasani said the victims discovered in the grave were reportedly members of the Sudan People's Liberation Army.

She said there were unconfirmed reports of least two more mass graves in Jebel-Kujur and Newside, near Juba.

Hundreds of thousands of people are believed to have fled to the countryside, leading to warnings of an imminent humanitarian disaster.

Tens of thousands more civilians have sought protection at badly overstretched UN bases.

At least 20,000 are sheltering at two bases in Juba, and another 17,000 in Bor, capital of the precarious eastern Jonglei state.

"The estimated number of people displaced in the current crisis in South Sudan has risen to 81,000," a UN report said.

"Given the limited access to civilians outside population centres, the number is likely to be significantly higher."                 

Bor, around 200km (125 miles) north of Juba, is an area of special concern.

"In Bor, the situation for the 17,000 people sheltering at the base is challenging, the lack of food and shelter is becoming urgent," the UN warned, adding there had been "large-scale looting of humanitarian compounds and civilian property" in the town.

"The situation in Jonglei deteriorated further, with reported clashes between different armed factions south of Bor ... the base is being reinforced with additional protective barriers, including the area hosting the displaced civilians," it added.

UN Secretary-General Ban Ki-moon has warned warring factions that reports of crimes against humanity will be investigated and asked the Security Council to vote to almost double the size of the UN mission in the country.

Fighting started more than a week ago when President Kiir accused his former deputy of attempting a coup.

Mr Machar has denied the claim and has in turn accused Mr Kiir of carrying out a vicious purge of his rivals.

The country has been blighted by ethnic divisions, corruption and poverty since it won independence in 2011.
