Russia Has Been Keeping Assad's Regime Running With Cash Injections

Over 200 tons of "bank notes" have been shipped to Syria from Moscow

This past summer, as the Syrian economy began to unravel and the military pressed hard against an armed rebellion, a Syrian government plane ferried what flight records describe as more than 200 tons of "bank notes" from Moscow.

The records of overflight requests were obtained by ProPublica. The flights occurred during a period of escalating violence in a conflict that has left tens of thousands of people dead since fighting broke out in March 2011.
