FBI and CIA are concerned that an unnamed militant group, which has apparently purchased an unmanned aerial vehicle (UAV), will use it for attacks against US interests. At the time, the agencies believed that the only reason to use this UAV would be for either reconnaissance or attack. The primary concern is that it will be used to attack outside the United States, for example, by flying a UAV into a US Embassy or a visiting US delegation. [US Congress, 9/18/2002]
