New light is shed on bin Laden's mindset

Hunkered down in his Pakistani compound, Osama bin Laden pleaded with his followers to stay focused on attacking the United States instead of being dragged into Muslim infighting.

Documents declassified on Wednesday shed new light on the mind-set of al-Qaida's founder, his debates over tactics, his anxiety over Western spying and his fixation with the group's media image.

"The focus should be on killing and fighting the American people and their representatives," bin Laden wrote in one of the newly revealed documents.
