The opening as it read in 2005

Hamburg cell was, according to U.S. and German intelligence agencies, a group of radical Islamists that included students who eventually came to be key operatives in the 9/11 attacks .1 Important members included Mohamed Atta al Sayed , who led the four hijacking teams in 2001 and piloted American Airlines Flight 11 ; Ramzi Binalshibh , who conspired with the other three members but was unable to enter the United States ; Marwan al-Shehhi , who piloted United Airlines Flight 175 ; and Ziad Jarrah , who piloted United Airlines Flight 93 . Less important members included Said Bahaji , Zakariya Essabar , Mounir el Motassadeq , and Abdelghani Mzoudi .2 On November 1 , 1998 , future-hijackers Mohammed Atta al Sayed , Marwan al-Shehhi , and Ramzi Binalshibh moved into a large four-bedroom apartment together on Marienstraße. Here they formed the secretive Hamburg cell, which also included Said Bahaji , Zakariyah Essabar , Mounir el Motassadeq , Abdelghani Mzoudi , and others. They met together three or four times a week to discuss their anti-American and anti-Semitic views, and to decide how best to fight for their cause. As late as 1999 , the four core members of the group had intended to wage jihad in Chechnya , where Islamic jihadists were then and are now rebelling against the parent country of Russia . The 9/11 Commission Report notes in Chapter 5 that "according to Binalshibh [who is now in U.S. custody], a chance meeting on a train in Germany caused the group to travel to Afghanistan instead. An individual named Khalid al Masri approached Binalshibh and Shehhi (because they were Arabs with beards, Binalshibh thinks) and struck up a conversation about jihad in Chechnya. When they later called Masri and expressed interest in going to Chechnya, he told them to contact Abu Musab in Duisburg , Germany. Abu Musab turned out to be Mohamedou Ould Slahi , a significant al-Qaeda operative who, even then, was well known to U.S. and German intelligence, though neither government apparently knew he was operating in Germany in late 1999." When Binalshibh and Shehhi visited Slahi in Duisburg, he convinced them that it would be best to train in Afghanistan first, because further experience would be useful, and anyway it was difficult at that time to get into Chechnya. Slahi instructed them to travel to Karachi , Pakistan , then to the Taliban office in Quetta , Afghanistan, where they were to contact a man named Umar al Masri. Atta and Jarrah left Hamburg during the last week of November , 1999. Shehhi left by himself around the same time; Binalshibh followed two weeks later. "Umar al Masri" turned out to be a nonexistent person. The name was a code word that instructed members of the Taliban office to escort the men to Kandahar , where they were convinced to join the al-Qaeda network and wage jihad against America . They met with Osama bin Laden himself and swore their loyalty to him. Mohamed Atta al Sayed was chosen by Bin Laden as the leader of the group that would attack America; Atta would contact Bin Laden several more times before the attacks. The men then returned to Germany to enroll in flight training school, and later moved on to flight training schools in the United States at the recommendation of one of their German instructors. The members of the Hamburg Cell were a boon to the 9/11 plot, which Khalid Shaikh Mohammed had proposed to Bin Laden in 1996 . The Hamburg students were fluent in English, educated, accustomed to the Western lifestyle, radically Islamic, and capable of learning to pilot aircraft. "Bin Laden and Mohammed Atef wasted no time in assigning the Hamburg group to the most ambitious operation yet planned by al-Qaeda," the 9/11 Commission Report says. Many al-Qaida members lived in the Hamburg apartment at various times. In all, 29 men listed the apartment as their home address while Mohamed Atta's name was on the lease. Reportedly, Khalid Shaikh Mohammed visited the apartment repeatedly. German intelligence monitored the apartment, but did not find any evidence against the residents. The CIA and German Intelligence have been widely criticized for failing to share information on these and other al-Qaida members.3
