🇺🇸💔🥲 The September 11, 2001 attacks were planned and carried out by the terrorist group al-Qaeda.
Osama bin Laden authorized the operation. Khalid Sheikh Mohammed was the principal planner. Nineteen men hijacked four commercial airliners:
• 15 were Saudi
• 2 were from the United Arab Emirates
• 1 was Egyptian (Mohamed Atta, who led the team)
• 1 was Lebanese
They crashed two planes into the World Trade Center towers in New York, one into the Pentagon, and the fourth (United 93) into a field in Pennsylvania after passengers fought back.
Al-Qaeda claimed responsibility. The 9/11 Commission Report and subsequent investigations confirmed this.
Bin Laden was killed by U.S. forces in 2011; Khalid Sheikh Mohammed was captured in 2003 and later convicted.
