Between Mid-August and September 10, 2001: ISI Director Learns Pakistani Nuclear Scientists Are Helping Al-Qaeda, but Fails to Take Action or Warn US

Some time before 9/11, ISI Director Lt. Gen. Mahmood Ahmed learns that two prominent Pakistani nuclear scientists met with Osama bin Laden and Ayman al-Zawahiri in Afghanistan in mid-August 2001. Bin Laden revealed to the two scientists, Sultan Bashiruddin Mahmood and Chaudiri Abdul Majeed, that he had acquired nuclear material and wanted their help to turn it into a weapon (see Mid-August 2001). ISI Director Mahmood is said to have learned about this through military contacts, as several Pakistani generals sit on the board of directors of a charity run by the two scientists that assists the Taliban. For instance, Hamid Gul, a former director of the ISI, is the charity’s honorary patron and was in Afghanistan at the time of the meeting. However, the ISI does not warn the US or take any action against the scientists or their charity. [Levy and Scott-Clark, 2007, pp. 310-311]
