Sudan's army says it has killed at least 300 rebels in clashes this week, while losing more than 70 of its own troops.
Sudanese state media on Saturday quoted General Al-Tayeb al-Musbah Osman as describing the fighting with the Darfur region's Justice and Equality Movement.
The Sudanese general said government forces destroyed rebels' vehicles during the series of clashes.
Violence in Darfur has increased since insurgent forces withdrew from peace talks in May.
The region has experienced seven years of war and instability since rebels took up arms in 2003, accusing the government of neglecting the western region.
The United Nations says fighting and related violence have killed 300,000 people and displaced more than 2.7 million. Sudan puts the death toll at 10,000.
