Mullah Dadullah, the Taliban's most prominent military commander, was killed in fighting in southern Afghanistan with Afghan and NATO troops, officials said Sunday. Dadullah was killed Saturday in the southern province of Helmand, said Said Ansari, the spokesman for Afghanistan's intelligence service. A government official in Kandahar province who spoke on condition of anonymity said he had seen Dadullah's body. NATO's International Security Assistance Force did not confirm the death but hinted that it was true. "You might want to keep pursuing it. It certainly is an issue that we're tracking," said spokesman Maj. John Thomas.
