Declassified 9/11 Briefings Reveal Warnings on Bin Laden, Hijack Threats
Declassified 9/11 briefings reveal warnings about Osama bin Laden, al-Qaeda, hijacking plans, Washington targets and dirty bomb efforts gathered by US intelligence before the attacks.
The documents detail security analysts’ efforts to track bin Laden’s movements and support network, along with concerns about possible threats to US targets. They also outline officials’ understanding of his network in the United States and other countries, including information about how his operations were financed.
CIA Director John Ratcliffe described the release as “an act of exceptional transparency”, saying the documents represented the agency’s single largest release of declassified presidential daily briefs, the highly classified briefings prepared by the nation’s intelligence community for the government’s most senior leaders.
The records span the period before and immediately after the September 11 attacks. Among them is a February 1998 file prepared for then-President Bill Clinton titled “Terrorists Seeking WMD Capability”, which mentioned bin Laden and other Islamic extremists.
An April 1998 document described the Taliban’s unwillingness to hand over bin Laden, who was then viewed as their “guest” in Afghanistan. The briefing said the Taliban’s “gratitude for his assistance during the Soviet occupation” was making them “reluctant to alienate him by monitoring or controlling his activities”.
Five months later, a briefer wrote that bin Laden’s “preferred option is to strike the US on its own soil in Washington” and warned that al-Qaeda “may fly an explosive-packed airplane into a US city”.
The possibility of hijackings was also discussed in December 1998. A briefer reported that conspirators “have evaded security checks during a recent trial run at an unidentified New York airport” and that “some members of the Bin Ladin network have received hijack training”.
Other documents detail bin Laden’s pursuit of materials to make “dirty bombs”, conventional weapons infused with radioactive material. By June 1999, according to intelligence officials, his operatives had conducted experiments involving explosives to “increase their energy output”.
The briefings also document concerns over bin Laden’s network, its support system and its activities across the United States and other countries. They show how intelligence officials were tracking his movements and examining the resources and financing behind his operations.
The documents extend beyond the attacks themselves. A September 12, 2001, report said a source indicated that the attacks had been planned for two years and had also targeted the US Capitol.
Many of the released documents were redacted to conceal the names of sources and other identifying information. The records did not appear to break new ground on the planning of the attacks or on US officials’ understanding of how the September 11 hijackings had unfolded.
Taken together, the declassified presidential daily briefs provide a detailed record of the intelligence officials had gathered about bin Laden and al-Qaeda before the attacks, including warnings about potential attacks on US soil, hijacking preparations, weapons capabilities and the network’s activities.
