(FILES) This file photo taken on September 11, 2001 shows a man standing in the rubble, and calling out asking if anyone needs help, after the collapse of the first World Trade Center Tower in New York City. Al-Qaeda mastermind Osama bin Laden was killed late on May 1, 2011 in a firefight with covert US forces deep inside Pakistan, prompting President Barack Obama to declare “justice has been done” a decade after the September 11 attacks.
