In the late autumn of 2001, when US-allied forces are overrunning Taliban positions in Afghanistan, the Darunta camp run by al-Qaeda is seized and searched. Al-Qaeda leader Midhat Mursi (a.k.a. Abu Khabab al-Masri) ran al-Qaeda’s WMD program and conducted crude chemical weapons experiments there. The CIA recovers one document there by Mursi that refers to connections between al-Qaeda and Pakistani nuclear scientists. It reads, in part, “As you instructed us you will find attached a summary of the discharges from a traditional nuclear reactor, amongst which are radioactive elements that could be used for military ends. One can use them to contaminate an area or halt the advance of the enemy. It is possible to get more information from our Pakistani friends who have great experience in this sphere.” [Bergen, 2006, pp. 345; Levy and Scott-Clark, 2007, pp. 294] This could be a reference to links between al-Qaeda and the Pakistani nuclear scientists working with the Ummah Tameer-e-Nau charity front (see 2000 and Mid-August 2001).
