Abu-Hafs

From 9/11 Encyclopedia:

Abu Hafs the Mauritanian is described as one Al-Quaeda leader,as reported, he was killed in the American bombing of Afghanistan. 
His other nicknames are Mahfouz Ould al-Walid or Khaled Al-Shanqiti. He blamed the CIA and FBI on the September 11th attacks,
in an interview with Yussef Al Shuli Al-Jazeera on November 30, 2001:

"In the U.S. [administration] there are [agencies] legally responsible for safeguarding the security of America and the Americans. 
It is they who should be held accountable. The biggest budget of all the intelligence apparatuses in the world is spent on American intelligence. 

The FBI, with offices everywhere and dozens of other apparatuses, is entrusted with safeguarding America's security, 
on which the Americans spend billions of dollars of their tax money and their private funds so they will ensure their security. 
Where were these apparatuses when these things occurred? 

These apparatuses have satellites, ground stations, millions of spies, and huge budgets.
It is said that they know what is happening in the bedrooms, that they know the shoe sizes of the wanted [men]. 

How did a group of people manage to stay for years, to train inside the U.S., and to plan this operation?" 
...Although we did not carry them out, these blows coincided with our interests, and their results were significant for us.
..Regarding what happened on September 11, and what was said and written about the killing of innocents and so on,
I have a clarification. First, as I said, we are not responsible for this act and therefore we are not responsible
for [issuing] religious explanations for it..."
