FBI again hunts al Qaeda's "dirty bomb" expert after seven years
DEBKAfile Exclusive Report

07 Aug. US federal agencies Saturday, Aug. 7, announced the hunt was on again for Adnan Al Shukrijumah, 35, who lived in the US for 15 years and may now be Al Qaeda's new global operations chief. 
DEBKAfile's counter terror sources confirm the wanted man is indeed dangerous - but not because of his climb up the al Qaeda ladder but owing to his unique seven-year old mission, first revealed by DEBKA-Net-Weekly 132 of Nov. 2003 as being a radiological bombing attack in America.
Already then, in October of that year, Shukriumah was the quarry of a secret manhunt in the US and Canada.  He was employed at the time as a nuclear engineering student at MacMaster University's nuclear 5-megawatt research reactor in Hamilton, Ontario, Canada before suddenly disappearing. 
His absence was noted when a large quantity of radioactive material was missed from the university's reactor. It was suspected then that Osama bin Laden had entrusted the "student" with preparing a "dirty bomb" attack in a North American city. 
Shukrijumah has never been traced since. 
Our experts would not be surprised to hear that Shukrijumah may be in the process of adjusting his operation for a dirty bomb or other unconventional strike in America according to the circumstances prevailing today.
