Hamburg cell

The Hamburg cell (German: Hamburger Zelle) or Hamburg terror cell (German: Hamburger Terrorzelle) was, according to U.S. and German intelligence agencies, a group of radical Islamists based in Hamburg, Germany that included students who eventually came to be key operatives in the 9/11 attacks. Important members included Mohamed Atta, who led the four hijacking teams in 2001 and piloted American Airlines Flight 11; Ramzi bin al-Shibh, who conspired with the other three members but was unable to enter the United States; and Marwan al-Shehhi, who piloted United Airlines Flight 175, Ziad Jarrah, who piloted United Airlines Flight 93 and failed to hit a target in Washington D.C., claimed by Khalid Sheikh Mohammed to have been the Capitol. Less important members included Said Bahaji, Zakariya Essabar, Mounir el-Motassadeq, and Abdelghani Mzoudi.

On November 1, 1998, future-hijackers Mohamed Atta, Marwan al-Shehhi, and Ramzi bin al-Shibh moved into a three-room apartment (two bedrooms, one living room, one kitchen) together on Marienstraße. Here they formed the secretive Hamburg cell, which also included other minor participants in the 9/11 plot. They met together three or four times a week to discuss their anti-American and anti-Israeli views, and to decide how best to fight for their cause.
