In the summer of 1999, the CIA asks border-control agencies in the Middle East to question anyone who may be returning from a training camp in Afghanistan, according to a 2004 Vanity Fair article. This is said to occur about six months before future 9/11 hijacker Ziad Jarrah is stopped and questioned at the airport in Dubai, United Arab Emirates, either because he is on a US watch list or because he shows signs of having come from Afghanistan, or both (see January 30, 2000 and December 14, 2001-September 28, 2005). [Vanity Fair, 11/2004] Also in 1999, the CIA specifically works out an arrangement with immigration officials at the Dubai airport to monitor or question suspected militants passing through (see 1999).
