German President Johannes Rau watched in shock as the World Trade Center collapsed on September 11, 2001, when nearly 3,000 people were killed by Islamist terrorists. Eleven Germans were among the victims, and it was later confirmed that three of the four suspected hijackers had recently lived in Hamburg. Mohammed Atta, a key figure behind the attacks, became radicalized at Hamburg's Al-Quds Mosque before leading the so-called Hamburg terrorist cell, which included six men, including Mounir al-Motassadeq, who was sentenced to 15 years for aiding and abetting thousands of murders. The article does not provide specific numbers on how many Germans were involved in investigations or detentions related to the attacks.
