Suspected Taliban gunmen ambushed a convoy of civilian trucks carrying vehicles to the U.S. military in southern Afghanistan, killing three of the drivers, an official said Saturday. "This shows that some in the Taliban or other anti-government insurgents will continue to try to destabilize Afghanistan through violent acts," U.S. spokeswoman Lt. Cindy Moore said. "There is still a threat out there." The gunmen attacked the trucks on Friday after they crossed the Pakistani border at Spin Boldak, 90 kilometers (55 miles) south of Kandahar city, Spin Boldak District Chief Fazeluddin Agha told The Associated Press. Three of the drivers _ two Pakistanis and one Afghan _ were killed in a hail of gunfire that severely damaged the trucks and two of the military vehicles, Agha said.
