(CNN) -- All 77 NATO service members wounded in a Saturday attack against a coalition base in Afghanistan are U.S. troops, a spokeswoman for the International Security Assistance Force said Sunday. Two Afghan civilians were killed and 25 others also were wounded in the attack, which occurred on the eve of the 10th anniversary of al Qaeda's attack on the United States on 9/11, U.S. Army Sgt. Lindsey Kibler said. None of the injuries is life-threatening, ISAF said, and those wounded are expected to return to duties "shortly." The truck bombing took place in the central-east province of Wardak, and those killed were Afghan laborers, said Shahidullah Shahid, the Wardak governor's spokesman.
