[4] During the Second Sudanese Civil War, White Army fighters mainly from the Lou Nuer subtribe backed the breakaway SPLM/A faction known as SPLA-Nasir, in attacks on the Dinka.
Among their most regular enemies were the Murle people, a rival tribe competing for land and cattle in the states of Jonglei and Upper Nile.
[3] The news service IRIN reported that more than 1,000 Lou Nuer men and boys in Akobo County who had been part of the White Army voluntarily surrendered their weapons to authorities in July 2006.
[7] In late December 2011, several months after South Sudan gained its independence, The Upper Nile Times reported that the Nuer White Army had re-formed and had issued a threat on Christmas Day 2011 to "wipe out the entire Murle tribe on the face of the earth as the only solution to guarantee long-term security of Nuer's cattle".
The declaration marked an escalation in the ongoing clashes between the SPLA, the Murle, and the Lou Nuer in Jonglei and Upper Nile, which began when armed Murle fighters under the influence of George Athor's South Sudan Democratic Movement launched a cattle raid against the Lou Nuer in Jonglei state.
