On this day 22 years ago, four coordinated terrorist attacks carried out by al-Qaeda, an Islamist extremist group, killed 2,977 people from 93 nations: 2,753 people were killed in New York; 184 people were killed at the Pentagon; and 40 people were killed on Flight 93. On September 11, 2001, nineteen terrorists from al-Qaeda hijacked four commercial airplanes, deliberately crashing two of the planes into the upper floors of the North and South Towers of the World Trade Center complex and a third plane into the Pentagon in Arlington, Virginia.  After learning about the other attacks, passengers on the fourth hijacked plane, Flight 93, fought back, and the plane crashed into an empty field in western Pennsylvania about 20 minutes by air from Washington, D.C. Today, September 11, 2023, the 22nd-anniversary commemorations of the terror attacks that killed almost 3000 Americans will occur in New York City, Virginia, and Shanksville, Pennsylvania.
