Where were they from the 9-11 terrorists?

The 9/11 terrorists were primarily from Saudi Arabia, with 15 of the 19 hijackers being Saudi nationals. The other four hijackers included individuals from the United Arab Emirates, Egypt, and Lebanon. They were members of the extremist group al-Qaeda, which was led by Osama bin Laden, who also had Saudi origins. The attacks were motivated by various political and ideological grievances against the United States and its foreign policies.
