South Sudan rebel chief issues war call from exile

South Sudan's rebel leader issued a call for renewed war with the government this weekend, declaring the collapse of an internationally-backed peace deal. Former vice president Riek Machar is in exile in Khartoum where he fled following fighting in the South Sudanese capital Juba in July. Machar's leadership of a faction of rebels, known as the SPLA/IO, is in question with former ally Taban Deng Gai having taken his position in government and international backers of the peace plan urging that efforts to end the war should move ahead, with or without Machar.
