The 9/11 attacks, also known as the September 11th attacks, were a series of coordinated terrorist attacks that were perpetrated by the Islamic extremist group al-Qaeda on September 11, 2001. The attacks resulted in the deaths of nearly 3,000 people and caused significant damage to New York City and Washington, D.C.
The attacks began early in the morning, when terrorists hijacked four commercial airplanes and crashed them into the World Trade Center in New York City and the Pentagon in Washington, D.C. A fourth plane, United Airlines Flight 93, was hijacked and crashed in a field in rural Pennsylvania after passengers attempted to take control of the plane.
The attacks were a major shock to the United States and the world, as they were the deadliest terrorist attacks in history at the time. They had a profound impact on international relations, leading to the War on Terror and the invasion of Afghanistan by the United States and its allies. The attacks also had a significant impact on the United States, leading to increased security measures, such as the creation of the Department of Homeland Security, and a shift in foreign policy.
The 9/11 attacks have had long-lasting consequences and continue to be remembered and commemorated around the world. They serve as a reminder of the importance of vigilance against terrorism and the need to work towards a more peaceful and secure world.
