In pictures: Killed al-Qaeda cleric Awlaki and his associates
Born in New Mexico, Anwar al-Awlaki, a U.S.-born cleric linked to al-Qaeda in Yemen, has used his website and English-language sermons to encourage Muslims around the world to kill U.S. troops in Iraq and has been tied by U.S. intelligence to the 9/11 hijackers, underwear bomber Umar Farouk Abdulmutallab, as well as Maj. Nidal Malik Hasan, the Army psychiatrist accused of killing 13 people in November at Fort Hood, Texas. A still image of a video taken November 8, 2010, from the website muslm.net.Reuters/muslim.net
