Survivors of Typhoon Haiyan pass the time at a school where hundreds have found shelter at, in Tacloban November 21, 2013. As millions of dollars pour in for more than four million left homeless by the typhoon in the central Philippines, authorities are grappling with a familiar problem - how to stop fraudulent claims and prevent greedy politicians taking advantage. Typhoon Haiyan smashed through the country on November 8, laying waste to just about everything in its path, and killing more than 4,000 people.
