Bin Laden papers reveal al-Qaeda leaders' 'frustrations'

Newly released papers from Osama Bin Laden's hideout reveal a frustrated al-Qaeda leader struggling to control an unruly network, the US military says.

The documents seized during the raid on the Abbottabad compound were posted online by the research wing of the US military academy, West Point.

The papers show he was unhappy with affiliates' attacks on fellow Muslims, urging them to target the US instead.

Seventeen documents were released from a cache of more than 6,000.
