South Sudan analysis

At the weekend, South Sudan Vice President Riek Machar reportedly fired a minister who he said had defected to his long-time rival President Salva Kiir's party. The rift between Machar and Taban Deng Gai has raised the prospect of further turmoil after months of fighting, as members of a faction led by Gai threatened to replace their leader. Two years of civil war that erupted after Kiir sacked Machar as Vice President in 2013, has killed more than 10-thousand people and displaced over 2 million, many of whom fled to neighbouring countries. In a letter to party members and his military commanders late on Friday, Machar said Gai will be relieved of his position as mining minister, and had been expelled from the party. Machar left the capital last week after a new outbreak of clashes, saying he would only return when an international body set up a buffer force to separate his forces from Kiir's.
