The September 11 attacks on America by al-Qaeda killed 2,977 people — 2,507 civilians, 343 firefighters, 72 law enforcement officers, and 55 military personnel. Two commercial airliners were deliberately flown into the twin towers of the World Trade Center, a third into the Pentagon, and a fourth, originally intended to target either the United States Capitol or the White House, crashed in a field in Stonycreek Township near Shanksville, Pennsylvania. It was also the deadliest foreign attack on American soil since the Japanese attack on Pearl Harbor on December 7, 1941.
