Answer:
The 9/11 attacks were a series of four coordinated terrorist attacks carried out by the Islamic extremist group al-Qaeda on September 11, 2001, in which nearly 3,000 people were killed and over 6,000 were injured. The attacks had a profound impact on the United States and the world, ushering in a new era of global security concerns and forever changing the way we think about terrorism and national security. In response, the US launched the War on Terror, which led to the invasion of Afghanistan and later, Iraq. The attacks also resulted in the creation of the Department of Homeland Security, the implementation of new security measures at airports and other public places, and increased surveillance and intelligence gathering activities. The significance of 9/11 lies not only in the scale of the tragedy itself but also in its lasting impact on global politics and security.
