What cause 9/11 attack in new york.

9/11 world-wide is known as a sad day (my birthday lol). Militants associated with the Islamic extremist group al-Qaeda hijacked four airplanes and carried out attacks against targets in the United States. They were allegedly acting in retaliation for America's support of Israel, its involvement in the Persian Gulf war and its continued military presence in the middle east. Hope this helped! Have a great day! :)
