NATO and Afghan officials say a top Taleban commander has been killed in fighting with Afghan and international troops in the nation's south.
NATO officials say the death of Mullah Dadullah is a "serious blow" to the Taleban insurgency.
An Afghan intelligence official Saeed Ansari says Dadullah was killed Saturday in Helmand province.
Dadullah is one of the highest-ranking Taleban leaders to be killed since US-led forces pushed the Taleban from power in Afghanistan in 2001.
Meanwhile, local officials say 55 suspected Taleban fighters have been killed in two separate battles with Afghan and international forces in the eastern province of Paktika near the Pakistani border.
Separately, officials say nine Afghan policemen were killed Sunday, eight when Taleban militants ambushed their vehicle in the western province of Nimroz.
