At some time in August 2001, Zacarias Moussaoui calls Naamen Meziche, who is an apparent member of the al-Qaeda cell in Hamburg, Germany, with a few of the future 9/11 hijackers. Moussaoui is in the US and will be arrested and imprisoned on August 16 (see August 16, 2001). Although it is not specified in news reports, presumably Moussaoui makes the call before his arrest, while he still is able to make calls. Meziche’s phone number is written on a piece of paper among Moussaoui’s belongings. FBI officials will not be allowed to search Moussaoui’s possessions until after 9/11. Presumably, if they had been able to, the call and phone number could have helped point investigators to the Hamburg cell and hijackers. Meziche is the son-in-law of Mohammed Fazazi, the radical imam of the Al-Quds mosque in Hamburg, Germany, regularly attended by three of the 9/11 hijackers (see 1993-Late 2001). He is also said to be a friend of hijacker Mohamed Atta. Meziche’s role in the Hamburg cell will only emerge after he is killed in a US drone strike in Pakistan in 2010 (see October 5, 2010). [Wall Street Journal, 10/16/2010] Before 9/11, German investigators are monitoring some members of the Hamburg cell (see for instance November 1, 1998-February 2001). Had that investigation widened to include Meziche, the call from Moussaoui could have been detected and changed the investigation of Moussaoui in the US.
