The Washington Post has

The Washington Post has a fascinating account of the activities of the September 11 plotters during the months leading up to the attacks. Among other things, the ease with which they traveled around the world is striking. We hear a lot about the difficulty an open society like the United States has in combatting terrorism, but the same can be said of most of the world. It is also interesting that the CIA was sufficiently aware of the plotters that they asked the Indonesian government to photograph their meeting in Kuala Lumpur in January 2000. Apparently this meeting was called following the failure of a series of attacks that had been intended to coincide with the millenium, and it was at the Kuala Lumpur meeting that plans for the attacks on the USS Cole as well as on Washington and New York were hatched.
