The '''Terrorist Attacks of September 11, 2001''' occurred when [[al Qaeda]]-affiliated [[Islam|Islamic extremists]] hijacked four transcontinental airliners and used them to strike targets in the [[United States]]; two aircraft destroyed the twin towers of the [[World Trade Center]] in [[New York City]]; the third crashed into a portion of the [[Pentagon]] in Washington, D.C.; and the fourth aircraft - in which the hijackers are believed to have targeted the White House or the Capital Building - crashed into an empty field near Shanksville, Pennsylvania after passengers fought back to re-take control.
