South Sudan's exiled opposition leader Riek Machar arrived in Juba on Saturday in a bid to salvage a peace deal with less than a month to go until he is to form a government with President Salva Kiir.
The foes, whose falling out in 2013 triggered a bloody civil war that has left almost 400,000 people dead and sparked a major humanitarian crisis, signed a peace deal in September last year that is meant to see them reunite once again in government.
