Bill Roggio, the managing editor of the Long War Journal website, cautioned that until Al Qaeda issues a statement acknowledging his death, it shouldn't be considered a sure thing. He describes Libi as "one of Al Qaeda's most prolific propagandists."
Between 2006 and 2010, he has appeared in more al Qaeda propaganda tapes than any other member of the terror group, including bin Laden and Zawahiri. He has weighed in on some of the most controversial and important issues on al Qaeda's agenda. He was the first al Qaeda leader to urge the Pakistani people and the Army to turn against then-President Pervez Musharraf's regime after the military stormed the radical Red Mosque in the heart of Islamabad.
