The September 11 attacks (also known as 9/11)^[f] were a series of four coordinated Islamist suicide attacks carried out as an act of terrorism by the militant group al-Qaeda against the United States of America. The attacks happened on the morning of Tuesday, September 11, 2001, and were done by 19 terrorists. The attacks killed 2,996 people (including the attackers),^[5] making it the deadliest terrorist attack in human history.^[6] They caused more than $10 billion in damage to infrastructure.^{[7][8][9][10][11]} The terrorists took control of 4 passenger airplanes to destroy 3 famous buildings, the Twin Towers and part of the Pentagon, by flying the planes into them. There were two attacks in New York City and one in Arlington, Virginia. The fourth attack, aimed at Washington, D.C. did not work and the plane crashed in a field (now, Flight 93 National Memorial) near Shanksville, Pennsylvania. The Twin Towers collapsed as a result of the crashes.

The buildings attacked were the World Trade Center's Twin Towers in New York City and the Pentagon in Arlington, Virginia. The fourth plane crashed in an empty field (now, Flight 93 National Memorial) in Shanksville, Pennsylvania before it could reach its target in Washington, D.C. That target was either the White House or the United States Capitol.^[12] After the event, the United States government said the people who had done the attacks were associated with the Islamist terrorist group al-Qaeda and the attacks had been organized by its leader Osama bin Laden.

The September 11 attacks are commonly attributed as the event that made the War on Terrorism begin.
