The September 11 attacks, commonly known as 9/11, were a coordinated series of suicide attacks carried out by the Islamist terrorist organization al-Qaeda against the United States on September 11, 2001. Nineteen hijackers seized four commercial airliners: two struck the World Trade Center’s Twin Towers in New York City, one hit the Pentagon in Arlington County, Virginia, and United Airlines Flight 93 crashed near Shanksville, Pennsylvania, after passengers resisted the hijackers. The attacks killed 2,977 people, injured thousands, and produced enduring political, security, and public-health consequences.
