US-led troops have killed a wanted Taliban commander in an air strike in Afghanistan's southwestern province of Badghis, US and Afghan officials said Monday. Mullah Dastagir along with eight other militants were killed in a raid on a village near Turkmenistan's border on Sunday night, they said. Dastagir was behind a series of attacks in Badghis, including an ambush in which 13 Afghan soldiers were killed last November, they added. Before that ambush, Dastagir had been jailed but was released by order of President Hamid Karzai, a defense ministry official said. The U.S. military confirmed the air strike and the casualties including Dastagir's killing. The Taliban could not be reached for comment. Separately, a roadside bomb killed three employees of a road construction company Monday in the eastern province of Kunar, the interior ministry said, adding three more were wounded in the blast.
