Shortly after 9/11, US officials are finally able to investigate the possessions of prisoner Zacarias Moussaoui, and they discover the phone number of Naamen Meziche on a piece of paper. Meziche is an apparent member of the al-Qaeda cell in Hamburg with a few of the 9/11 hijackers, although his involvement in the cell will only be made public after he is killed by a US drone strike in Pakistan in 2010 (see October 5, 2010). He is a French citizen of Algerian descent, and a longtime resident of Hamburg, Germany. Investigators also learn that Moussaoui called Meziche’s number at some time in August 2001 (presumably before Moussaoui’s arrest on August 16 (see Early August 2001)). German intelligence begins investigating Meziche and discovers more phone and e-mail communications with suspected al-Qaeda operatives. Few details are publicly released, but one detail is known: on September 5, 2001, hijacker associate Ramzi bin al-Shibh called Meziche from the airport as he was leaving Germany for Pakistan in anticipation of the 9/11 attacks (see September 5, 2001). Police ask dozens of witnesses for evidence against Meziche. In 2002, Meziche is questioned by police and denies getting the calls from bin al-Shibh or Moussaoui. [Wall Street Journal, 10/16/2010] In 2003, the German government secretly classifies Meziche as a threat. An investigation is launched in 2004 with the hope of charging him with forming a terrorist organization, but it is later suspended. On March 5, 2009, Meziche flies to Pakistan with a group of radical Islamists from Pakistan and attends training camps (see March 5, 2009). [Der Spiegel (Hamburg), 10/11/2010] After Meziche’s death in the 2010 drone strike, German investigators will express their frustration at being unable to arrest him. On several occasions, suspects have been pulled off of airplanes just before takeoff, only to be released a few hours later. One unnamed intelligence official will say: “You can’t charge them with a crime until they show up in a terrorist camp. And then we can only hope they don’t return.” [Wall Street Journal, 10/16/2010]
