9/11 hijacker Mohamed Atta returns to Germany from Pakistan using the same monitored route as he traveled on the outward journey (see Late November-Early December 1999). He flies from Karachi to Istanbul, Turkey, where he changes planes for Hamburg. Turkish intelligence discovered that militants use this route to travel between Europe and training camps in Afghanistan in the mid-1990s and alerted Germany to it at that time, causing Germany to launch an investigation into one of Atta’s associates (see 1996). However, it is not known whether the intelligence agencies register Atta’s travel at this time. [Stern, 8/13/2003] Fellow alleged 9/11 hijacker Ziad Jarrah appears to be noticed on his way back to Germany from Afghanistan (see January 30, 2000) and another member of the cell, Ramzi bin al-Shibh, may be monitored in Kuala Lumpur, Malaysia, at this time (see January 5-8, 2000).
