September 11 attacks

After repeated denials,^[ in 2004, Osama bin Laden claimed responsibility for the September 11, 2001 attacks on the United States. The attacks involved the hijacking of four commercial passenger aircraft, the subsequent destruction of those planes and the World Trade Center in New York City, New York, severe damage to The Pentagon in Arlington, Virginia, and the deaths of 2,974 people and the nineteen hijackers. In response to the attacks, the United States launched a War on Terror to depose the Taliban regime in Afghanistan and capture al-Qaeda operatives, and several countries strengthened their anti-terrorism legislation to preclude future attacks. The CIA's Special Activities Division was given the lead in tracking down and killing or capturing bin Laden.
The Federal Bureau of Investigation has stated that classified evidence linking al-Qaeda and bin Laden to the attacks of September 11 is clear and irrefutable. The UK Government reached a similar conclusion regarding al-Qaeda and Osama bin Laden's culpability for the September 11, 2001 attacks, although the government report notes that the evidence presented is not necessarily sufficient for a prosecutable case. Bin Laden initially denied involvement in the attacks. On September 16, 2001, bin Laden read a statement later broadcast by Qatar's Al Jazeera satellite channel denying responsibility for the attack.
In a videotape recovered by U.S. forces in November 2001 in Jalalabad, bin Laden was seen discussing the attack with Khaled al-Harbi in a way that indicates foreknowledge. The tape was broadcast on various news networks on December 13, 2001. The merits of this translation have been disputed. Arabist Dr. Abdel El M. Husseini stated: "This translation is very problematic. At the most important places where it is held to prove the guilt of bin Laden, it is not identical with the Arabic."

In the 2004 Osama bin Laden video, bin Laden abandoned his denials without retracting past statements. In it he stated he had personally directed the nineteen hijackers. In the 18-minute tape, played on Al-Jazeera, four days before the American presidential election, bin Laden accused U.S. President George W. Bush of negligence on the hijacking of the planes on September 11.
