US officials tell ABC News that al Qaeda's No. 3 -- Mustafa Ahmed Muhammad Uthman Abu al-Yazid, known as Shaikh Sa'id al-Masri and Mustafa Abu al-Yazid -- has been killed. Al Qaeda released a eulogy of Shaikh Sa'id tonight, officials said."Word is spreading in extremist circles of the death of Sheikh Sa'id al-Masri, widely viewed as the number three figure in al-Qaeda," a US official told ABC News. "We have strong reason to believe that's true, and that al-Masri was killed recently in Pakistan's tribal areas. In terms of counterterrorism, this would be a big victory."
US officials believed him to have been killed about a week ago in Pakistan.
