Nine Ugandan and Kenyan nationals were killed and one captured alive during an attack on a cattle camp in Kapoeta East County of Eastern Equatoria state.
A Turkana from Kenya who was captured alive identified two of the dead as his tribe mates and two others as Dodoth and five Karamojong of Najie, Kotido district of Uganda.Kapoeta East County Commissioner Titus Lokwachuma told Radio Emmanuel that six Toposa, including two children, were wounded in the raid.
Some were admitted to Narus Primary Health Care Centre for treatment.
Nine cattle were also killed, 42 wounded and 20 stolen by the foreign raiders.
Mr Lokwachuma said a combined group of criminals from Turkana of Kenya, and Dodoth, Jie and Karamojong of Uganda on March 29 midnight attacked a Toposa cattle camp at Lomil village in Natinga Payam.
He added that the attack occurred few days after he evacuated the cattle keepers from Ugandan game park protected areas where they were grazing their animals.
The Commissioner said due to the remoteness of the location, it was impossible for the victims to communicate in time to get rescue.
Ugandan and Kenyan authorities said they were not aware of the attack and promised to cooperate in tracking the suspects down.
Commissioner Lokwachuma called the attack a criminal act by small elements from neighbouring foreign communities.
He noted that the Karamojong and Dodoth of Uganda could not launch an organized cattle raid on their close Toposa friends of South Sudan.
Mr Lokwachuma blamed criminals among the Turkana of Kenya for allegedly instigating such violent attack on the Toposa community.
