The following is an excerpt from an Iranian TV series about 9/11:
What group or organization was responsible for the events of 9/11? The intellectuals, who support globalization and oppose America's policy, believe that it was the US that created the events of 9/11 in order to expand its hegemony in the world.
The FBI and CIA experts attributed the Events of 9/11 to the Muslims and Al-Qa'ida. Moreover, two months after the events, part of Bin Laden's speech was broadcast by Al-Jazeera, in which he said, "We calculated the number of enemy victims ahead of time, and predicted the number of people to be killed in the towers." Some experts expressed doubts about tape's authenticity and considered it to be the work of the CIA. In light of the wide scope of the operation, which required coordinating four airplanes by at least 20 people, who would engage in combat and carry out a suicide operation, the likelihood that this was an Al-Qa'ida operation is low.
