Who are al-Qaeda’s leaders? According to a 1998 federal indictment, al-Qaeda is administered by a council that “discussed and approved major undertakings, including terrorist operations.” At the top is bin Laden. Ayman al-Zawahiri, the head of Egyptian Islamic Jihad, is thought to be bin Laden’s top lieutenant and al-Qaeda’s ideological adviser. At least one senior al-Qaeda commander, Muhammad Atef, died in the U.S. air strikes in Afghanistan, and another top lieutenant, Abu Zubaydah, was captured in Pakistan in March 2002. In March 2003, the alleged mastermind of the September 11 attacks, Khalid Shaikh Muhammad, and al-Qaeda’s treasurer, Mustafa Ahmed al-Hawsawi, were also captured in Pakistan.
