The Sudanese army says has clashed with Darfur rebels over the past few days killing and capturing hundreds.
General Al-Tayeb al-Musbah Osman told the state news agency that the army killed at least 300 members of the rebel Justice and Equality Movement, captured another 86 and destroyed dozens of their vehicles.
He added in late Friday's report that 86 Sudanese soldiers lost their lives.
JEM said it had clashed with government forces and defeated them.
The joint U.N.-African Union peacekeeping force in the area confirmed fighting took place but provided no casualty figures.
Ethnic Africans in Sudan's arid Darfur region revolted against the Arab-dominated central government in 2003 and in the ensuing war some 300,000 people have died.
