In Yemen, at least one child killed was a U.S. citizen. In 2011, Denver-born Abdulrahman al-Awlaki was 16 years old when he was killed in an air strike. He was the son of suspected terrorist Anwar al-Awlaki, who was killed in an air strike two weeks before. However, later reports indicate that he had little contact with his father and did not have any ties to terrorism.
