On September 11, 2001, 19 militants linked with 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, which destroyed the towers completely. The third plane hit the Pentagon just outside Washington, D.C., and the fourth plane crashed in a field in Pennsylvania. According to various sources about 3,000 people were killed during these attacks. These attacks made terrorism a global problem and has posed threat to global security.
