Berlin: The United Nations says it has discovered a mass grave containing about 75 bodies in South Sudan.
UN's human rights chief says the mass grave was found in Bentiu in the country's oil rich Unity State.
Navi Pillay said in a statement released Tuesday that at least two other mass graves are reported to have been found in Juba.
A spokeswoman for the Geneva-based human rights office says the bodies in Bentiu reportedly belonged to ethnic Dinka who were members of the Sudan People's Liberation Army.
She says it is unclear who was responsible for the killings.
Shamdasani says the other two reported mass graves are in Jebel-Kujur and Newside, near Eden.
