South Sudanese rebels have accused the government of resuming their military attacks. This comes just a day after President Salva Kiir opted not to sign a peace deal, aimed at ending the civil war.
Rebel leader Riek Machar said the government had chosen war over peace.
But Mr Kiir's chief negotiator said the deal was a sell-out that could not be implemented as the rebels are split.
