After gunfire broke out in South Sudan especially in the stronghold of Vice-President Riek Machar, the UN Security Council has called on warring factions to immediately end the recent fighting and prevent the spread of violence.
According to a statement from the Security Council, the fresh fighting is counterproductive adding it was shocked and outraged that UN sites were not spared.
Hundreds have been reportedly killed in clashes between rival groups since Friday forcing the UN to call for additional peacekeepers. Friday's exchanges were apparently sparked by a shootout between President Kiir's and Mr Machar's bodyguards. At least 150 died in the clashes.
Forces loyal to Vice-President Riek Machar say government troops supporting President Salva Kiir attacked their positions in the capital, Juba.
A spokesman for Mr Machar told the BBC on Sunday that the country was "back to war" - but Information Minister Michael Makuei Lueth described reports of war as "dishonest".
South Sudan became an independent country in July, 2011 after more than 20 years of guerrilla warfare which claimed the lives of at least 1.5 million people and displaced more than four million.
