The '''Islamic terrorist attacks of September 11, 2001''' occurred when [[al Qaeda]] [[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 Capitol Building - crashed into an empty field near Shanksville, Pennsylvania after passengers fought back to re-take control.

The attacks were a direct or indirect cause of massive changes in United States domestic policy.
