US Commemorates 9/11 at the former World Trade Center Site in New York
The attacks killed 2,977 people and left thousands of bereaved relatives and scarred survivors. The planes carved a gash in the Pentagon, the U.S. military headquarters, and brought down the trade center’s twin towers, which were among the world’s tallest buildings.
The catastrophe also altered U.S. foreign policy, domestic security practices, and the mindset of many Americans who had not previously felt vulnerable to attacks by foreign extremists.
