Source: Russia prisoner swap involving US journalist Evan Gershkovich under way | Russia | The Guardian A major prisoner exchange between Russia and the west is under way involving the Wall Street Journal reporter Evan Gershkovich, who has been freed from Russian custody, Bloomberg has reported, citing people familiar with the situation. Sources with knowledge of the planned exchange confirmed to the Guardian that a major swap would take place on Thursday in a location outside Russia. They declined to make further details public until after the swap had taken place owing to sensitivity of the matter. Gershkovich and the former US marine Paul Whelan, both accused by Russian authorities of espionage, had already been freed and were en route to a destination outside Russia, Bloomberg reported. The Guardian understands the exchange will also involve Russian political prisoners being freed as well as numerous Russians jailed in the west for espionage, murder and other crimes being returned to Russia.
