Part 1 of 5 · freeIntroduction
On Tuesday, September 11, 2001, nineteen members of Al-Qaeda, the terrorist group founded by Osama bin Laden, hijacked four planes. Two hit the World Trade Center in New York, a third the Pentagon, the headquarters of American defense. The fourth crashed in Pennsylvania after the passengers fought back.
The toll: 2,977 dead. Beyond the horror of the day, the attack ended any hope of a calmer world order and set off a chain of conflicts that still shape the 21st century.
