(REUTERS) — JUBA, Dec 24 — A mass grave believed to contain the bodies of 75 ethnic Dinka soldiers has been found in South Sudan, the United Nations said on Tuesday, fuelling fears of ethnic bloodletting in the world's newest state.
President Salva Kiir said on Tuesday government troops had retaken control of Jonglei state capital Bor, a key town which last week fell to rebels loyal to former Vice-President Riek Machar, who was sacked by Kiir in July.
U.N. human rights officers discovered the grave in the rebel-held city of Bentiu, capital of Unity state.
