The National Security Archive, has released documents relating to pre-9/11 warnings to Saudis that Osama Bin Laden, might target civilian airliners.
More than three years before the 9/11 attack on the United States, U.S. officials warned Saudi Arabia that Osama bin Laden "might take the course of least resistance and turn to a civilian (aircraft) target," according to a declassified cable released by the National Security Archive today.
The State Department cable was not mentioned in the report of the 9/11 Commission. It was obtained under the Freedom of Information Act by Archive analyst Barbara Elias.
The National Security Archive released the cable, and a CIA memorandum, "We're at War," written by then director George Tenet, as it prepared to commemorate its 20th anniversary on Friday.
