Some Russian prisons might be mistaken for vacation destinations based on their nicknames, which include animal appellations such as the Black Dolphin and the Polar Owl.

The return of 35 Ukranian prisoners and 35 Russian prisoners is a move that could ease tensions between the two countries after Moscow's annexation of Crimea in 2014. "Today we can finally say safely that the mutual return of Ukrainian and Russian citizens has been conducted," Russian Human Rights Ombudswoman Tatyana Moskalkova said, Russian state news agency TASS reported Saturday. After landing in Kiev, the Ukrainian prisoners were seen greeting and hugging their emotional family members on the runway. Vyshinsky considered the accusations against him a lie and a form of manipulation, according to Russian state news agency RIA-Novosti. Before the exchange, Russian President Vladimir Putin on Thursday said it would be a "good step forward towards the normalization" of relations between the two nations, Reuters reported.
