Alsu Kurmasheva, a Russian-American journalist for Radio Free Europe/Radio Liberty is also in the exchange . She was captured by the Russians when she went there to visit her sick grandmother . The Russians said she was spreading false stories in her reporting about their war in Ukraine .
There are other countries involved too . Germany is one . All I have seen so far in reports is that the Russians being released are "spies " . Evidently Turkey is brokering the swap.
