Ethnic Conflict in South Sudan

As background to the current situation in South Sudan, you might want to read the 13 September 2013 Human Rights Watch report titled "They Are Killing Us: Abuses against Civilians in South Sudan's Pibor County."  The report documents abuses against civilians in Pibor County by Sudan People's Liberation Army (SPLA) forces.  The report deals with longstanding ethnic conflict involving Dinka Bor, Lou Nuer and Murle in Jonglei State.
