kiir at splm rally

South Sudan’s President Salva Kiir (C) acknowledges his supporters as he arrives to address a rally at John Garang’s Mausoleum in the capital Juba March 18, 2015, on the peace talks process with South Sudan’s rebel leader Riek Machar. Fighting since December 2013 between forces loyal to Kiir and rebels allied with his former deputy Machar has reopened ethnic fault lines that pit Kiir’s Dinka people against Machar’s ethnic Nuer forces.
