Two apparent associates of the al-Qaeda cell in Hamburg, Germany, Ismail Bin Murabit (a.k.a. Ismail Ben Mrabete) and Labed Ahmed (a.k.a. Ahmed Taleb), purchase tickets to fly to Pakistan on September 3, 2001. They will be joined on that flight by cell member Said Bahaji (see September 3-5, 2001). All three will disappear into Afghanistan thereafter. It is later discovered that Ahmed had been in e-mail contact with al-Qaeda leader Abu Zubaida. [Chicago Tribune, 2/25/2003] Note that these purchases occur one day before Zacarias Moussaoui’s arrest in Minnesota, suggesting the date for the 9/11 attacks was set before his arrest (see August 16, 2001).
