Bin Laden's threatening audio and video pronouncements are on the internet, according to the State Department.

Letters seized at the compound where Osama bin Laden was hunted down indicate he was grooming Hamza bin Laden to take over leadership of Al Qaeda, according to the U.S. department.

The younger Bin Laden, now roughly 30, is said to be married to the daughter of 9/11 mastermind Mohammed Atta.

Under United Nations action Thursday, member states are required to freeze bin Laden's assets and ensure he is not able to use them as points of travel, State Department ambassador-at-large and counterterrorism coordinator Nathan A. Sales said in a statement posted on Twitter.

Sales and State Department Assistant Secretary of State for Diplomatic Security Michael T. Evanoff announced the reward.
