The Kremlin said Wednesday that a Russian citizen was freed in the United States in exchange for Moscow’s release of American Marc Fogel, but refused to identify them until they arrive in Russia.

A Russian citizen was released as part of an exchange involving American teacher Marc Fogel and will return to Russia soon, the Kremlin said.

In a high-profile prisoner exchange, American teacher Marc Fogel has been released from Russian custody after serving over three years for drug charges. The Kremlin confirmed the swap, withholding details about the Russian national released in return.
