South Sudan's Machar urges delay to unity government as peace efforts stall

South Sudan’s main opposition accused the government on Wednesday of failing to push through a peace deal and called for a six-month delay in the formation of a unity administration, casting a shadow over efforts to end years of fighting.

The spokesman for former rebel leader Riek Machar said he did not believe he would be able to join a unity government on November 12 - a deadline agreed in September after months of talks, broken ceasefires and pressure from the United Nations, the United States and regional powers.
