The CIA releases declassified presidential intelligence briefings related to 9/11

(NBC, KYMA) - On the 25 year remembrance of those who died on September 11th, the CIA has declassified presidential briefings connected to the attacks.

The 71 once classified presidential documents date back to 1998 and cover the period leading up to the 9/11 attacks.

The documents, which were posted Friday on the CIA's website, are all drawn from the president's daily brief or PDB, a summary of the most important intelligence presented to the commander-in-chief by the CIA and other spy agencies.

The CIA says it was the largest scale declassification of documents about the attacks since the 9/11 commission's report in 2004.

In one document the CIA gave to the president, days before the September attacks, the agency shares that Bin Laden's Al Qaida's organization stresses careful planning, tight security practices and flexibility through all stages of terrorist strikes.

The briefing says Bin Laden's followers are expert in executing different types of attacks, are flexible in decision making and know how to protect their plans from discovery.

Days later the U.S. was attacked on September 11, 2001.
