Which terrorist group was responsible for the September 11th terrorist attacks on New York and Washington

Al Qaeda

Explanation:

It was on September 11, 2001. This group hijacked four airplanes and carried out attacks against targets in the United States. Two of the planes were flown into the twin towers of the World Trade Center in New York City, a third plane hit the Pentagon just outside Washington, D.C., and the fourth plane crashed in a field in Shanksville, Pennsylvania. This was one of the biggest terrorist attacks the US has ever had. There were a total of 3,000 people who died on that day.

Hope this helped :)
