Although nearly 3,000 people were killed in the terrorist attack on the World Trade Center on September 11, 2001, the first attack on the WTC took place on February 26, 1993, when a bomb exploded in a parking garage underneath the North Tower of the World Trade Center. Although it failed to topple either of the twin towers, the blast killed six people, including a pregnant woman, and caused over a thousand injuries.
The 9-11-2001 attack on the World Trade Center on 9/11 resulted in the largest loss of life by a foreign attack on American soil. After the 9-11 attack, only 18 people were rescued alive from the rubble of the World Trade Center.
