In 2001, terrorists attacked the United States. They hijacked passenger airplanes and flew two of them into the World Trade Center.  In turn, the towers collapsed, killing thousands of people.  I am really sorry about this event.

To get a basic understanding of what happened, I think you’ll find that people often describe it as a war between radical Islam and the United States. The 9/11 attacks were directed by Al Qaeda and occurred on September 11th, 2001.
