Who helped Osama bin Laden in the terrorist attack?

Answer 1

After his father's death in 1968, Osama bin Laden, founder of Al-Qaeda (extremist Sunni Islamist militant group),inherited some estimated $300 million. By the early part of the 21st century, bin Laden was the leader of a network of terrorist cells throughout the world.

On September 11, 2001, 19 terrorists hijacked four passenger planes, two from American Airlines and two from United Airlines. In an unprecedented act of terrorism, the hijackers crashed two of them into New York City's 110-story twin towers of the World Trade Center, killing over 5000 civilians. One American Airlines plane crashed into the Pentagon, killing more than 100 people. The fourth plane crashed in a rural area in Pennsylvania. The passengers probably hindered the hijackers to attack another building in Washington. Osama bin Laden is suspected to be the key financier and instigator of the terrorist attacks.
