The crisis in oil-rich South Sudan escalated on Wednesday as fighting spread beyond the capital, Juba, where two days of clashes between rival army factions have left at least 500 dead and hundreds more wounded.
The fighting has brought back memories of the 1990s factionalism that plagued the Sudan People’s Liberation Movement, the group that fought against Sudan’s army in the north until the south won independence in July 2011.
Western diplomats are increasingly worried that ethnic divisions could tear apart the world’s newest country, hampering oil production in eastern Africa. Oil companies on Wednesday started to evacuate their staff, industry executives said.
