One of the five senior Taliban leaders transferred to Qatar in exchange for Sgt. Bowe Bergdahl played a key role in al Qaeda’s plans leading up to the September 11, 2001, terrorist attacks. Mohammad Fazl, who served as the Taliban’s army chief of staff and deputy defense minister prior to his detention at Guantánamo, did not have a hand in planning the actual 9/11 hijackings. Along with a notorious al Qaeda leader, however, Fazl did help coordinate a military offensive against the enemies of the Taliban and al Qaeda in Afghanistan the day before. And Osama bin Laden viewed that September 10 offensive as an essential part of al Qaeda’s 9/11 plot.

The 9/11 Commission found that the hijackings in the United States on September 11, 2001, were the culmination of al Qaeda’s three-step plan. First, on September 9, 2001, al Qaeda assassinated Northern Alliance commander Ahmed Shah Massoud in a suicide bombing. Massoud’s death was a major gift to the Taliban because he was their chief rival and still controlled parts of the country. The assassination was also intended to weaken opposition to the Taliban and al Qaeda within Afghanistan before the United States could plan its retaliation for the most devastating terrorist attack in history. The Northern Alliance did, in fact, play a role in America’s response.
