September 11 attacks

September 11 attacks. On the morning of Tuesday, September 11, 2001, nineteen terrorists from the Islamist militant group al-Qaeda hijacked four commercial airliners. They carried out coordinated suicide attacks against targets in the United States, crashing two planes into the World Trade Center complex in New York City and one into the Pentagon in Arlington County, Virginia. The fourth plane, United Airlines Flight 93, crashed into a field near Shanksville, Pennsylvania, after passengers attempted to regain control, preventing it from reaching its intended target in Washington, D.C.. The attacks resulted in nearly 3,000 deaths, caused at least $10 billion in infrastructure and property damage, and triggered major U.S. initiatives to combat terrorism.

Background

The origins of the plot are traced to Khalid Sheikh Mohammed, who first presented the idea to Osama bin Laden and Mohammed Atef in the early 1990s. Bin Laden, the founder and leader of al-Qaeda, provided the funding, resources, and overall authority for the operation, which was seen as a declaration of war against the United States and its allies. The motivations were rooted in al-Qaeda's ideology, which opposed American foreign policy in the Middle East, particularly U.S. support for Israel and the presence of American troops in Saudi Arabia following the Gulf War. Key planners, including Ramzi bin al-Shibh and Zacarias Moussaoui, helped coordinate the hijackers, who began arriving in the U.S. in early 2000 and took flight lessons at various schools, including ones in Florida and California.

Attacks

On the morning of September 11, the hijackers boarded four early-morning transcontinental flights: American Airlines Flight 11 and United Airlines Flight 175 from Boston, American Airlines Flight 77 from Washington Dulles International Airport, and United Airlines Flight 93 from Newark Liberty International Airport. At 8:46 a.m. EDT, Mohamed Atta and other hijackers crashed American Airlines Flight 11 into the North Tower of the World Trade Center. Seventeen minutes later, Marwan al-Shehhi and his team crashed United Airlines Flight 175 into the South Tower. At 9:37 a.m., Hani Hanjour piloted American Airlines Flight 77 into the western façade of the Pentagon. The fourth plane, United Airlines Flight 93, crashed in Somerset County, Pennsylvania at 10:03 a.m. after a passenger revolt, believed to have been targeting either the United States Capitol or the White House.

Aftermath

Immediate responses included the complete shutdown of U.S. airspace by the Federal Aviation Administration and the evacuation of numerous high-profile buildings, including the United States Capitol and United Nations Headquarters. President George W. Bush addressed the nation from the Oval Office and later delivered a speech at Ground Zero. The attacks led to the creation of the United States Department of Homeland Security and the passage of the USA PATRIOT Act. Internationally, NATO invoked Article 5 of the North Atlantic Treaty for the first time in its history, declaring the attacks an attack on all member states. This precipitated the War in Afghanistan, launched in October 2001 to dismantle al-Qaeda and remove the Taliban regime harboring them.

Victims and casualties

The attacks killed 2,977 victims and the 19 hijackers. At the World Trade Center site, 2,606 people died, including 343 New York City Fire Department firefighters and 71 law enforcement officers from the New York City Police Department and the Port Authority of New York and New Jersey. At the Pentagon, 125 people were killed. All 44 people aboard United Airlines Flight 93 died in Pennsylvania. The victims represented over 90 countries, and thousands more suffered from long-term health effects due to exposure to toxic dust and debris at Ground Zero. The official memorials, the National September 11 Memorial & Museum in New York City and the Pentagon Memorial in Arlington County, Virginia, were later dedicated to the victims.

Investigation and responsibility

The investigation, led by the Federal Bureau of Investigation under the code name PENTTBOM, quickly identified the 19 hijackers and established links to al-Qaeda. The 9/11 Commission, formally known as the National Commission on Terrorist Attacks Upon the United States, was established in late 2002 to provide a comprehensive account of the circumstances. Its final report, published in 2004, detailed intelligence failures, including missed communications between the CIA and FBI, and outlined the planning and execution of the attacks by Khalid Sheikh Mohammed and his associates. The mastermind, Khalid Sheikh Mohammed, was captured in Rawalpindi in 2003 and is held at the Guantanamo Bay detention camp.

Legacy

The events profoundly altered U.S. domestic and foreign policy, leading to a global focus on counterterrorism and the initiation of the War on Terror. Security protocols worldwide were drastically enhanced, particularly in aviation with the creation of the Transportation Security Administration. The attacks had a significant cultural and psychological impact, influencing everything from literature and film to public discourse on security and civil liberties. The rebuilding of the site resulted in the construction of One World Trade Center, the National September 11 Memorial & Museum, and the World Trade Center Transportation Hub. The day is commemorated annually as Patriot Day in the United States. Category:September 11 attacks
