At around 9:30 pm on September 11, 2001, George Tenet, director of the Central Intelligence Agency (CIA) told the president and U.S. senior officials inside the bunker underneath the White House that the CIA's Counterterrorism Center had determined that Osama Bin Laden and al-Qaeda were behind the September 11 attacks. Two weeks after 9/11, the Federal Bureau of Investigation connected the hijackers to al-Qaeda, a militant Salafist Islamist multi-national organization. In a number of video, audio, interview and printed statements, senior members of al-Qaeda have also asserted responsibility for organizing the September 11 attacks.
