Nairobi - Tens of thousands of people have died in South Sudan during one year of warfare and the country's leaders are putting their "personal ambitions" ahead of the young nation's future, the UN secretary-general said on Monday.
A year ago on Monday fighting broke out in South Sudan's capital, Juba, and spiralled across the country. The UN says more than 1.9 million people have been displaced by the warfare, battles that often pit fighters loyal to President Salva Kiir, an ethnic Dinka, against those who support former Vice President Riek Machar, an ethnic Nuer.
UN Secretary-General Ban Ki-moon called on South Sudan's leaders to agree to an inclusive power-sharing arrangement that would address the root causes of the conflict and ensure accountability for any crimes committed on the battlefield.
There is no official death toll for the conflict, but Ban said "tens of thousands" of South Sudanese have died. The fighting has been marked by vicious atrocities, largely ethnic in nature.
The two sides have signed several peace deals brokered by neighbouring governments, but none has succeeded in stopping the fighting in the oil-rich country.
The UN Security Council blamed South Sudan's "man-made political, security and humanitarian catastrophe" and the threat of famine on its feuding leaders. In a presidential statement issued Monday, it again threatened targeted sanctions against those impeding the peace process.
South Sudan's civilians face a "dreadful" situation and have been victims of targeted killings and looting, said the UN High Commissioner for Human Rights, Zeid Ra'ad Al Hussein.
"The people of South Sudan are living in a tinderbox, with emotions high, an abundant flow of weapons and with both sides recruiting fighters, often forcefully and including children," Al Hussein said.
Government troops and armed youths have been battling in Upper Nile state in recent days, a sign that widespread violence could return now that the six-month rainy season has ended.
