Osama bin Laden Consistently Denied Any Responsibility for 9/11
A few days after the attack he said:
“I would like to assure the world that I did not plan the recent attacks, which seems to have been planned by people for personal reasons.” https://edition.cnn.com/2001/US/09/16/inv.binladen.denial/
On September 28, 2001, bin Laden told the newspaper Karachi Ummat:
“I have already said that I am not involved in the 11 September attacks in the United States. As a Muslim, I try my best to avoid telling a lie. Neither had I any knowledge of these attacks nor do I consider the killing of innocent women, children and other humans as an acceptable act. Islam strictly forbids causing harm to innocent women, children and other people.
“I have already said that we are against the American system, not against its people, whereas in these attacks, the common American people have been killed. The United States should try to trace the perpetrators of these attacks within itself; the people who are a part of the US system.
“There are intelligence agencies in the US, which require billions of dollars worth of funds from the Congress and the government every year. They need an enemy.”
