United States invasion of Afghanistan
On the morning of 11 September 2001, al-Qaeda carried out four coordinated attacks on the United States. Four commercial passenger jet airliners were hijacked. The hijackers – members of al-Qaeda's Hamburg cell – intentionally crashed two of the airliners into the Twin Towers of the World Trade Center in New York City. Both buildings collapsed within two hours from fire damage related to the crashes, destroying nearby buildings and damaging others. The hijackers crashed a third airliner into the Pentagon in Arlington County, Virginia. The fourth plane crashed into a field near Shanksville, Pennsylvania, after some of its passengers and flight crew attempted to retake control of the plane, which the hijackers had redirected toward Washington, D.C., to target the White House or the United States Capitol. No flights had survivors. In total, 2,996 people, including the 19 hijackers, died and more than 6,000 others injured in the attacks. According to the New York State Health Department, 836 first responders, including firefighters and police personnel, had died as of June 2009.
History of the United States (1991–2008)
On the morning of September 11, 2001, four airliners were hijacked by 19 members of the terrorist organization al-Qaeda. The first hijacked airliner, American Airlines Flight 11, struck the North Tower of the World Trade Center at 8:46 A.M. (EST) in New York City; with a second, United Airlines Flight 175, striking the South Tower less than twenty minutes later at 9:03 A.M. (EST), resulting in the collapse of both 110 story skyscrapers, and the destruction of the World Trade Center. The third hijacked plane, American Airlines Flight 77, was crashed into the Pentagon (the headquarters of the United States Department of Defense) in Arlington County, Virginia, demolishing a section of the outer southwest facing wall. After discovering that their plane, United Airlines Flight 93, was going to be used as a missile, passengers attempted to regain control of the plane which had been redirected towards Washington, D.C. However, after regaining control from the hijackers, the plane crashed near a rural community near Shanksville, Pennsylvania. In total, the attacks killed 2,996 people—2,507 civilians, 343 firefighters, 72 law enforcement officers, 55 military personnel, and the 19 terrorists. The 9/11 attack was the single deadliest international terrorist incident and the most devastating foreign attack on American soil since the Japanese surprise attack on Pearl Harbor on December 7, 1941. It refocused American attention to a long war on terrorism, beginning with an attack on al-Qaeda and its Taliban supporters in Afghanistan.
