An Egyptian and former member of Egyptian Islamic Jihad, Abu Khabab (Midhat Mursi al- Sayyid ‘Umar) served as al-Qa’ida’s bomb, chemical and biological expert as well as head of the organization’s al-Zabadi chemical weapons program. Though he is most recognized for his role in conducting chemical weapons experiments on dogs and various other animals, as depicted in video tapes acquired by CNN journalists in his former laboratory in Afghanistan, he is also linked to a number of attempted as well as successful high-profile terrorist attacks. Abu Khabab was believed to have been killed in a 2006 missile strike but U.S. officials now maintain that he did not die in the operation and is still at large.
