“On September 11, 2001, 19 militants associated with the Islamic extremist group al-Qaida hijacked four airplanes carring out suicide attacks against targets in the United States. Two of the planes flew into the twin towers of the World Trade Center in New York City, a third plane hit the Pentagon, & the fourth plane crashed in a field in Shanksville, Pennsylvania. Almost 3,000 people were killed during the 9/11 terrorist attacks, which triggered major U.S. initiatives to combat terrorism and defined the presidency of George W. Bush.”
