The World Trade Center was destroyed on 09/11/2001 by hijackers who crashed commercial airline flights into the twin towers.  As I write this, it is estimated that 5,000 people lost their lives.  Most believe that the world will never be the same after this day.

Nearly two weeks after the attacks brought down the twin towers, families of the victims and rescue workers have begun to face the reality that many of the more than 6,000 missing victims may never be recovered.

Afghanistan's hard-line Taliban geared up for threatened U.S. attacks September 24, 2001 by mobilizing troops, seizing U.N. food stocks and appealing to the American people to avert a 'vain and bloody war.' But their chief spokesman insisted the isolated leadership would still not hand over Osama bin Laden unless Washington, which blames him for the devastating September 11 suicide plane attacks provides evidence. Bin Laden is seen in an undated Interpol wanted poster. (Interpol via Reuters)
