The 9/11 terrorist attacks were a series of coordinated suicide attacks carried out by the extremist group al-Qaeda on September 11, 2001, targeting the United States. These attacks involved the hijacking of four commercial airplanes, with two being flown into the Twin Towers of the World Trade Center in New York City, one into the Pentagon in Arlington, Virginia, and the last crashing in Pennsylvania. The devastating impact of these attacks reshaped global politics and security measures, prompting significant changes in how countries, including Canada, responded to terrorism and global conflicts.
