As the US contends with the destruction caused by two ferocious hurricanes in three weeks, it is also marking the 16th anniversary of one of the nation's most scarring days- 9/11
The 9/11 attacks were a series of four coordinated terrorist attacks by the Al-Qaeda on the United States on the morning of September 11, 2001. The attacks killed 2,997 people, injured over 6,000 others, and caused at least $10 billion in infrastructure and property damage.
The Islamic extremist group Al-Qaeda hijacked four airplanes and carried out suicide attacks against targets in the United States. Two of the planes were flown into the twin towers of the World Trade Center in New York City, a third plane hit the Pentagon just outside Washington, DC, and the fourth plane crashed in a field in Pennsylvania.
Within an hour and 42 minutes, both 110-story towers collapsed, with debris and the resulting fires causing partial or complete collapse of all other buildings in the World Trade Center complex, including the 47-story 7 World Trade Center tower, as well as significant damage to ten other large surrounding structures. A third plane, American Airlines Flight 77, was crashed into the Pentagon (the headquarters of the United States Department of Defense) in Arlington County, Virginia, leading to a partial collapse of the building's western side. The fourth plane, United Airlines Flight 93, initially was steered toward Washington, D.C., but crashed into a field in Stonycreek Township near Shanksville, Pennsylvania, after its passengers tried to overcome the hijackers.
The attacks triggered major US initiatives to combat terrorism and defined the presidency of George W Bush.
