Juba, 5 August 2014 - The UN Mission in South Sudan (UNMISS) condemns in the strongest possible terms the killing by the so-called Mabanese Defence Forces of at least five South Sudanese employees of humanitarian non-governmental organizations (NGOs) earlier today in and around Bunj, Maban County, in Upper Nile State. Two of the victims were murdered in Bunj Town, a third aid worker is reported as missing but presumed dead. Another three died in an ambush as they were attempting to return to the town. The militia group is reportedly targeting civilians of Nuer origin after they clashed with defecting Nuer soldiers and suffered casualties.
