German intelligence is tapping the telephone of al-Qaeda operative Mohammed Haydar Zammar, and on this date, Zammar gets a call from a “Marwan.” This is later found to be future 9/11 hijacker Marwan Alshehhi. Marwan talks about mundane things, like his studies in Bonn, Germany, and promises to come to Hamburg in a few months. German investigators trace the telephone number and determine the call came from a mobile phone registered in the United Arab Emirates (UAE). [US Congress, 7/24/2003 ; Deutsche Presse-Agentur (Hamburg), 8/13/2003; New York Times, 2/24/2004] Although the call is short and seemingly innocuous, according to Vanity Fair, some “parts of the conversation seemed redolent of some kind of conspiratorial code.” For instance, at one point, Alshehhi says, “I’ve heard your mother died.” Zammar replies: “Yes, she passed on. She left me alone.” Alshehhi then asks: “But your father didn’t travel with you? I’ve seen him here.” Zammar answers, “No, my father is here.” Regarding whether or not it actually is code, a senior German official will later say: “Our desk officer had a certain feeling about that call.… You can say it was his nose—not that there was any single statement, but he had a feeling that there could be more behind it.” The desk officer writes a report about the call. Then, about a month later, the BfV (German domestic intelligence) will contact the CIA and ask for more information about men from the UAE named Marwan, and for help in tracing the phone number (see March 1999).
