September 11 Terrorist Attacks

The September 11 attacks were four coordinated Islamist terrorist suicide attacks carried out by al-Qaeda against the United States in 2001, resulting in the deaths of 2,977 people. On the morning of September 11, 19 terrorists hijacked four commercial airliners, crashing two into the Twin Towers of the World Trade Center in New York City, one into the Pentagon in Arlington County, Virginia, and one into a field in rural Pennsylvania after passengers revolted against the hijackers. The attacks led to a global war on terror, with the United States invading Afghanistan to depose the Taliban and expel Al-Qaeda.learn more on wikipedia
