Security Council members were given until 1900 GMT to raise objections to the USA request and diplomats confirmed that Russian Federation and Angola had blocked the move.

Under a peace agreement signed by President Salva Kiir and rebel leader Riek Machar, a ceasefire was due to enter into force on August 29 but fighting has continued, notably in Upper Nile state.

Earlier in the day MPs from both the government and rebel sides of the South Sudan conflict had spoken of their experiences of protracted and repeated civil war.

“We call on the South Sudan authorities to take the necessary steps to ensure the safety and security of NGO staff and assets in Juba and elsewhere in South Sudan”, the statement said.

South Sudan’s rebels on Thursday ratified the IGAD-Plus’s compromise peace agreement and vowed to fully implement the internationally-backed pact.

“I am committed to peace and the implementation of the agreement in order to overcome the challenges of humanitarian and economic crisis that are facing our people today in the country” Kiir told the citizen through the media, Tuesday”.

“The IGAD-prescribed peace document is the most divisive and unprecedented document seen in the history of our country”, Kiir said Tuesday in a speech in the capital, Juba.

The meeting to be held on the sidelines of the UN General Assembly would include envoys from key neighboring countries as well as the United States, Britain and other European states seeking to end the war.

Since this conflict began, fighting and abuses have forced over 2 million people to flee their homes and thousands of civilians have been killed, often targeted because of their ethnicity or perceived political allegiance.

The United States and other Western donors have accused Kiir and Machar of squandering goodwill after South Sudan’s independence and hindering development in an oil-producing nation with almost no tarmac roads and heavily reliant on aid.

There are also misgivings over the establishment of a joint command council of senior military officers of rival forces to monitor and verify the mechanisms of ground, an over-sight which the government genuinely fears could derail the swift implementation of the latest South Sudan peace deal.
