S Sudan on precipice of civil war, Obama warns

US President Barack Obama has warned that South Sudan is on the "precipice" of a civil war, after clashes in the capital Juba spread around the country.

He said 45 military personnel had been deployed to South Sudan on Wednesday to protect American citizens and property.

At least 500 people are believed to have died since last weekend, when President Salva Kiir accused his ex-deputy Riek Machar of a failed coup.

Two Indian peacekeepers were killed on Thursday when a UN base sheltering refugees at Akobo, Jonglei state, came under attack, the UN mission to the country, Unmiss, said on Friday. An injured Indian soldier was taken to hospital, it said.

Earlier reports said three Indian peacekeepers had been killed in the attack.

UN deputy spokesman Farhan Haq said more casualties were feared, and he did not know the fate of more than 30 Dinka civilians sheltering at the base.

The recent unrest has pitted gangs from the Nuer ethnic group of Mr Machar against Dinkas - the majority group to which Mr Kiir belongs.

"South Sudan stands at the precipice. Recent fighting threatens to plunge South Sudan back into the dark days of its past," President Obama said in a letter to Congress.

"Inflammatory rhetoric and targeted violence must cease. All sides must listen to the wise counsel of their neighbours, commit to dialogue and take immediate steps to urge calm and support reconciliation."
