The South African military says one of its troops was killed in Sudan's Darfur region when rebels there ambushed a South African unit that is part of a U.N.-African Union peacekeeping mission.

The military said in a statement that a South African soldier was also seriously injured in the attack on Sunday morning.

The statement says South African troops repelled the ambush.

Darfur has been in turmoil since 2003, when ethnic Africans rebelled, accusing the Arab-dominated Sudanese government of discrimination. The United Nations says 300,000 people have died in the conflict and 2.7 million have fled their homes.

Sudan's president, Omar al-Bashir, is wanted by the International Criminal Court on charges of genocide and war crimes for atrocities linked to the Darfur fighting. Al-Bashir rejects the court's authority.
