Saudi Arabia & 9/11
The Saudi government's possible foreknowledge of or support for the 9/11 attacks has been investigated for over two decades. Declassified documents show connections between hijackers and Saudi officials, and FBI materials obtained by 9/11 families point to Saudi government complicity.
Fifteen of the nineteen 9/11 hijackers were Saudi citizens. The 28 pages of the Joint Congressional Inquiry were classified for 15 years. When they were released in 2016, they documented connections between the hijackers and Saudi government officials. The FBI is still in litigation over what it knows.
Overview
The connection between the Saudi government and the 9/11 hijackers has been the subject of classified investigations, declassified revelations, and ongoing litigation for over two decades. The basic facts are not disputed: 15 of 19 hijackers were Saudi nationals, the attack was planned by al-Qaeda under Osama bin Laden (a Saudi dissident), and al-Qaeda received financing through Saudi-connected channels.
What remained classified for years — and remains the subject of ongoing FBI litigation — is the question of whether Saudi government officials, as opposed to private Saudi citizens, provided support or assistance to the hijackers.
The "28 Pages" — a classified section of the 2002 Joint Congressional Inquiry into 9/11 — were declassified in July 2016 after years of advocacy by the families of victims. The pages documented connections between hijackers and Saudi officials in the US, including a Saudi Embassy employee who helped two hijackers find housing in San Diego and a Saudi intelligence officer who was in contact with al-Qaeda.
The 9/11 families have sued the Saudi government under the Justice Against Sponsors of Terrorism Act (JASTA). In the course of that litigation, the FBI has been ordered to produce documents from its investigation — materials that the bureau initially sought to keep classified under state secrets privilege. The documents, partially released since 2021, further document contacts between Saudi officials and the hijackers.
"I believe the 9/11 families have a right to this information. It should have been declassified years ago." — Senator Bob Graham, co-chair of the Joint Congressional Inquiry, who spent 13 years advocating for the release of the 28 pages

Key Players
Omar al-Bayoumi
Identified in FBI documents as a Saudi intelligence asset who helped hijackers Nawaf al-Hazmi and Khalid al-Mihdhar obtain housing and financial support in San Diego.
Fahad al-Thumairy
Saudi consular official and imam who facilitated contacts with the San Diego hijackers. Deported from the US in 2003.
Prince Bandar
Saudi Ambassador from 1983-2005. His wife's charitable payments flowed to al-Bayoumi's wife. Bandar denies knowledge.
What the FBI Documents Show
The FBI documents released since 2021 in response to court orders in the 9/11 families' lawsuit contain the most specific evidence of Saudi government connections to the hijackers in the public record.
The documents detail how Omar al-Bayoumi — assessed by the FBI as a Saudi intelligence asset — met hijackers al-Hazmi and al-Mihdhar in a San Diego restaurant in January 2000 shortly after they arrived in the US. Al-Bayoumi then helped them find an apartment, co-signed their lease, threw them a welcome party, and helped them open bank accounts.
Al-Bayoumi had no visible source of income beyond a Saudi company that appears to have been a shell, yet his stipend doubled around the time he was assisting the hijackers. His phone records showed extensive contact with Saudi Embassy and consulate officials.
The FBI assessed that al-Bayoumi "acted as a Saudi intelligence asset" and had "tasked" contacts in the US. The Saudi government has consistently denied any official involvement.
"The FBI assessed al-Bayoumi acted as a Saudi intelligence asset." — Declassified FBI investigative document released under court order in 2021
The 28 Pages
The declassified 28 pages were more significant than the government's years of resistance suggested they might be. The section documented:
Multiple points of contact between the San Diego hijackers and Saudi officials and Saudi citizens with connections to the Saudi government.
Evidence that the hijackers received assistance from individuals connected to the Saudi government, including financial support.
The name of a senior Saudi official — whose name remains redacted in the released version — who had contact with the hijackers.
The 28 pages noted that the CIA had "no evidence that the Saudi government as an institution or senior Saudi officials individually funded al-Qaeda" — a crucial qualifier. The documented connections were with lower-level officials and intelligence assets, not with Saudi leadership.
The Bottom Line
The evidence that Saudi government employees — not just private Saudi citizens — assisted the 9/11 hijackers is substantial and documented. The evidence of direction from Saudi leadership is not established. Two decades of classification delayed the families of victims from accessing information they had a right to.
