Anwar al-Awlaki, a leader in Al Qaeda's outpost in Yemen, did not leave much of a trail, frustrating the American and Yemeni officials pursuing him.
They believed they finally had found him in a village in southern Yemen last year. Yemeni commandos, equipped with tanks and heavy weapons, surrounded the hamlet, but he slipped away, according to a Yemeni official. In May, his pursuers targeted him in a drone attack, but narrowly missed him and other members of his entourage as they drove across a desert.
The search for Mr. Awlaki, the American-born cleric whose fiery sermons made him a larger-than-life figure in the shadowy world of jihad, finally ended on Friday. After several days of surveillance of Mr. Awlaki, armed drones operated by the Central Intelligence Agency took off from a new, secret American base in the Arabian Peninsula, crossed into northern Yemen and unleashed a barrage of Hellfire missiles at a car carrying him and other top operatives from Al Qaeda’s branch in Yemen, including another American militant who had run the group’s English-language Internet magazine.
