"We have Russia's similar refusal to give out Kolchenko. Sad day," he wrote.
Earlier, Petukhov published a reply by Russia's Justice Ministry regarding the impossibility to transfer Ukraine's another political prisoner Sentsov due to the fact he has Russian citizenship.
Since the beginning of Russia's military aggression against Ukraine, several Ukrainian citizens have been taken hostage by the Kremlin. The exact number of Russian-held Ukrainians is unknown. At this point, according to official data, some 20 Ukrainians are being held for political reasons in Russian prisons, including in occupied Crimea. The story of captive Ukrainian pilot Nadiia Savchenko caused a massive public outcry.
Hennadii Afanasiev and Yurii Soloshenko were among the Ukrainian political prisoners held in Russia. Afanasiev was sentenced to seven years in prison as a suspect in the case against Ukrainian film-maker Oleh Sentsov charged with organizing a terrorist group in occupied Crimea and sentenced to 20 years in prison. Afanasiev was tried under a special procedure after he agreed to testify against other defendants. However, at the trial of Sentsov and Oleksandr Kolchenko, Afanasiev refused to testify, claiming torture during interrogation.
