"Months of investigation by The New York Times, centered on extensive interviews with Libyans in Benghazi who had direct knowledge of the attack there and its context..."

"...turned up no evidence that Al Qaeda or other international terrorist groups had any role in the assault."

The attack was led, instead, by fighters who had benefited directly from NATO’s extensive air power and logistics support during the uprising against Colonel Qaddafi. And contrary to claims by some members of Congress, it was fueled in large part by anger at an American-made video denigrating Islam....

Anger at the video motivated the initial attack. Dozens of people joined in, some of them provoked by the video and others responding to fast-spreading false rumors that guards inside the American compound had shot Libyan protesters. Looters and arsonists, without any sign of a plan, were the ones who ravaged the compound after the initial attack, according to more than a dozen Libyan witnesses as well as many American officials who have viewed the footage from security cameras.
