From the start of U.S. investigations into the terrorist attacks of Sept. 11, 2001, the question of whether the Saudi government might have been involved has hovered over the case.
The FBI, after the most extensive criminal probe in its history, concluded that a low-level Saudi official who helped the first two hijackers in California met them by chance and aided them unwittingly. The CIA said it saw no evidence of a higher-level Saudi role. The bipartisan 9/11 commission adopted those findings. A small FBI team continued to dig into the question, turning up information that raised doubts about some of those conclusions.
But now, 23 years after the attacks, new evidence has emerged to suggest more strongly than ever that at least two Saudi officials deliberately assisted the first Qaida hijackers when they arrived in the United States in January 2000.
Whether the Saudis knew the men were terrorists remains unclear. But the new information shows that both officials worked with Saudi and other religious figures who had ties to al-Qaida and other extremist groups.
Most of the evidence has been gathered in a long-running federal lawsuit against the Saudi government by survivors of the attacks and relatives of those who died. That lawsuit has reached a critical moment, with a judge in New York preparing to rule on a Saudi motion to dismiss the case.
Already, though, information put forward in the plaintiffs’ case — which includes videos, telephone records and other documents that were collected soon after the attacks but were never shared with key investigators — argues for a fundamental reassessment of the Saudi government’s possible involvement with the hijackers.
The court files also raise questions about whether the FBI and CIA, which repeatedly dismissed the significance of Saudi links to the hijackers, mishandled or deliberately downplayed evidence of the kingdom’s possible complicity in the attacks that killed 2,977 people and injured thousands more.
“Why is this information coming out now?” asked retired FBI agent Daniel Gonzalez, who pursued the Saudi connections for almost 15 years. “We should have had all of this three or four weeks after 9/11.”
Saudi officials have long denied any involvement in the plot, emphasizing that they were at war with al-Qaida well before 2001.
They have also leaned on earlier U.S. assessments, especially the one-page summary of a joint FBI-CIA report that was publicly released by the Bush administration in 2005. That summary said there was no evidence that “the Saudi Government or members of the Saudi royal family knowingly provided support” for the attacks.
Pages of the report that were declassified in 2022 are more critical of the Saudi role, describing extensive Saudi funding for Islamic charities linked to al-Qaida and the reluctance of senior Saudi officials to cooperate with U.S.
