Anwar al-Awlaki, the U.S.-born Muslim cleric said to have inspired the failed "underwear bomber" and the Fort Hood shooter, was killed Friday in an airstrike on a convoy in northern Yemen.
U.S. and Yemeni officials confirmed Friday that al-Awlaki, who was on a CIA terrorist hit list, was among four people killed in an attack by U.S. warplanes and unmanned drones near the border with Saudi Arabia.
