Russia and the United States carried out a historic prisoner exchange, the BBC writes.
A total of 24 people have been released on the margins of the deal that involved at least seven countries.
The swap of prisoners was the result of years of complicated behind-the-scenes negotiations involving the U.S., Russia, Belarus and Germany.
Eight people were swapped back to Russia in exchange for the release of 16 people who were held in Russian detention, including four Americans.
