Americans Killed in Car Bomb Attack
KABUL, Afghanistan -- A security firm has confirmed that four civilian contractors killed in a suicide car bombing in Afghanistan were Americans. Thursday's bombing in Kabul also killed two American soldiers and nine Afghan civilians, including two children. DynCorp International says four of its employees were working with U.S. forces training the Afghan military when the blast occurred. It was the bloodiest attack in the Afghan capital since March 9, when suicide bombers struck while U.S. Secretary of Defense Chuck Hagel was visiting. President Hamid Karzai condemned the attack, saying it was the work of terrorists and enemies of Afghanistan's peace. An Islamic militant group, Hizb-e-Islami, claimed responsibility for the early morning bombing, saying its new martyrdom unit stalked the convoy for weeks.
