Moscow's Sheremetyevo Airport, until recently the home of whistleblower Edward Snowden, reportedly holds another secret: 20 billion ($32.7 billion) in cash unclaimed for the past six years.
That's enough money to cover the EU's predicted budget shortfall for 2013. No one is sure who it belongs to, and many doubt its very existence.
Some sources have said it was sent by Saddam Hussein, while others offer the Government of Iran as the owner. Those trying to claim it allegedly include Ukrainian spies, Chechen gangsters, al-Qaeda members and even the Knights of Malta.
On August 7, 2007 security company Brink's flew from Frankfurt to Moscow and delivered 200 wooden pallets with 20 billion in 100 notes owned by one "Farzin Koroorian Motlagh", according to a Sheremetyevo delivery document printed by the newspaper Moskovsky Komsomolets, which broke the story.
The document does not list a recipient. Several Russian intelligence agencies took control of the shipment, which has not yet been claimed, the newspaper reported.
