TOPSHOT-SSUDAN-POLITICS-PEACE-AGREEMENT

TOPSHOT - A billboard featuring portraits of the South Sudan's President Salva Kiir (L) and the opposition leader Riek Machar (R)is displayed in Juba, South Sudan, on April 14, 2016. Preparations are on to forge a unity government with Machar taking the post of vice president. Machar's return to the capital Juba is expected on April 18, 2016. It is potentially one of the most significant steps towards peace since a repeatedly broken deal made in August 2015. The two leaders come from the south's two main ethnic groups, Kiir from the Dinka people and Machar from the Nuer. They fought both alongside and against each other during the long and bitter war with Khartoum. Civil war erupted in December 2013 after Kiir accused troops loyal to Machar of staging a failed coup, a claim Machar denies. The pair are now due to set up a transitional unity government.
