World Trade Center site
On the morning of September 11, 2001, Islamic terrorists affiliated with Al-Qaeda hijacked American Airlines Flight 11 and United Airlines Flight 175, both which were en route to Los Angeles, and intentionally crashed them into the two main towers of the World Trade Center. The towers collapsed within two hours of the collisions. 2,606 people, including 2,192 civilians, 71 law enforcement officers, and 343 firefighters, who were in the towers and in the surrounding area died in the attacks, as well as 147 civilians and the 10 hijackers aboard the two airliners. After the collapse of the World Trade Center, hospital workers and law enforcement officers began referring to the World Trade Center site as "Ground Zero".
Kenneth O'Keefe
On Iran's Press TV program, "The Agenda", while speaking on the topic of "America: Is it a Civilized Nation?", O'Keefe denied the plausibility that the September 11 attacks were committed by Osama bin Laden and the 19 hijackers. He claimed it was an inside job and that the US government and intelligence agencies, including Mossad, were responsible. He has repeated this view in an article on his own website, in which he states "Israeli Mossad worked with high treason traitors in the US government to set explosives in the twin towers and building 7 on 9/11 so as to instigate the fraudulent 'War on Terror'".
