[NDIL] In August 2010, a lawsuit was brought by the American Civil Liberties Union on behalf of radical Yemeni cleric Anwar al-Awlaki's father, Nasser al-Awlaki, that sought to remove the cleric from a CIA and U.S. military target list of terrorists to be killed or captured. According to a U.S. government's motion opposing the lawsuit, Anwar al-Awlaki was involved in preparing Christmas Day bomber Umar Farouk Abdulmuttalah in the attempted midflight bombing of a Northwest Airlines jet traveling from Amsterdam to Detroit on December 25, 2009.
