CIA Warned of Attacks in 1995

Six years before the Sept. 11 attacks, the CIA warned in a classified report that Islamic extremists likely would strike on U.S. soil at landmarks in Washington or New York, or through the airline industry, according to intelligence officials.

Though hauntingly prescient, the CIA's 1995 National Intelligence Estimate did not yet name Osama bin Laden as a terrorist threat.

But within months the intelligence agency developed enough concern about the wealthy, Saudi-born militant to create a specific unit to track him and his followers, the officials told The Associated Press.

The CIA after 1997 with collected vast amounts of intelligence on bin Laden and al-Qaida, which resulted in thousands of individual reports circulated at the highest levels of government. These carried titles such as "Bin Laden Threatening to Attack U.S. Aircraft" in June 1998 and "Bin Laden's Interest in Biological and Radiological Weapons" in February 2001.
