The 9/11 Truth Movement is a group of individuals and organizations that question the official account of the events surrounding the terrorist attacks on September 11, 2001. They believe that the U.S. government may have been involved in or had prior knowledge of the attacks, which targeted the World Trade Center and the Pentagon. Advocates of the movement often cite inconsistencies in the official reports and seek to investigate alternative theories regarding the collapse of the Twin Towers and Building 7. The movement has gained attention through documentaries, books, and public demonstrations, aiming to raise awareness and promote further inquiry into the events of that day.
