Juba, Jumada I 09, 1437, February 18, 2016, SPA -- At least seven people have been killed in clashes at a United Nations camp housing displaced people in South Sudan, the UN mission to the war-torn country said Thursday, according to dpa. Youths belonging to the Dinka and Shilluk ethnic groups fought with machetes Wednesday evening in the camp, which houses nearly 48,000 displaced people in the northern city of Malakal, the mission said. Seven people were killed and at least 40 others were injured. A UN spokeswoman declined to comment on whether the clashes only involved displaced people, or whether government or rebel forces participated in the fighting. UN police used tear gas in an attempt to restore order at the camp, where violence continued Thursday morning. The UN mission reminded "all concerned ... of the sanctity of UN assets and personnel." UN Secretary General Ban Ki-moon condemned the violence and expressed concern over the growing tensions between the Dinka and Shilluk groups, said Stephane Dujarric, Ban's spokesman, in New York. --SPA 00:11 LOCAL TIME 21:11 GMT www.spa.gov.sa/w
