Laden was worried about the future of al-Qaeda in his final days

Osama bin Laden complained of 'disaster after disaster' befalling al-Qaeda, and was worried about the future of his terror group in his final days, a trove of documents obtained from his Abbottabad compound has revealed.

White House counter-terror official John Brennan said that US intelligence analysts learned bin Laden was worried about his legacy as his terror group was struggling to attract new recruits to replace leaders killed in US operations.

"With its most skilled and experienced commanders being lost so quickly, al-Qaeda has had trouble replacing them," News24 quoted Brennan, as saying.

"In documents we seized, he confessed to 'disaster after disaster'," Brennan added.

According to the report, things got so bad for the group that bin Laden even considered changing the group's name.

Brennan said the documents show that bin Laden urged his group's leaders to flee Pakistan's tribal regions and seek refuge in areas free of 'aircraft photography and bombardment'.
