An undated file video grab released by the Central Intelligence Agency (CIA) on November 1, 2017 and taken by researchers from the Federation for Defense of Democracies' Long War Journal, shows an image from the wedding of killed Al-Qaeda leader Osama Bin Laden's son Hamza. The CIA has put online 470,000 additional files seized in May 2011 when US Navy SEALs burst into the Abbottabad compound and shot dead the leader of Al-Qaeda's global extremist network. According to Thomas Joscelyn and Bill Roggio, scholars from the Foundation for Defense of Democracies who were allowed to study the trove before it was made public, it provides new insights. "These documents will go a long way to help fill in some of the blanks we still have about al Qaeda's leadership," Roggio said. The inclusion of Hamza Bin Laden's wedding video, for example, gives the world public the first image of Bin Laden's favorite son as an adult -- an image apparently shot in Iran.
