Verkhovna Rada Human Rights Commissioner Liudmyla Denisova has asked Director of Russia's Federal Security Service Alexander Bortnikov to take measures to return to Ukraine the crewmembers of the YaMK-0041 vessel, Ukrainians Serhiy Kalinichenko, Oleh Blok and Ruslan Skrypnyk, who are still being held in Russian-annexed Crimea.

"They are continuing to illegally hold Ukrainians Serhiy Kalinichenko, Oleh Blok and Ruslan Skrypnyk on the territory of the annexed Crimea. Just because law enforcement officers of the aggressor unreasonably seized their passports for going abroad," she wrote on her Facebook page on Thursday.

She noted that after almost six months, all three sailors and their families are physically and morally depleted.

"Serhiy Kalinichenko's health has deteriorated significantly. He suffers from palmar fibromatosis requiring qualified treatment. Oleh Blok, before his detention, took care of his 83-year-old mother. She is now practically in a helpless state without a son, unable to keep house, buy food," Denisova wrote.

In addition, according to her, Skrypnyk's two children have stayed without a father for almost half a year.

"Now the family does not have the funds to support and teach the children, because they were left without a breadwinner," Denisova said.

She recalled that even on September 11, the FSB had informed her that measures of procedural enforcement had not been applied to these three persons.

"Last week, a Russian presidential advisor responded to my request that no one took foreign passports from the ship's crew and their freedom of movement was not restricted. But they still cannot leave the territory of Crimea. Last Sunday, we still managed to return crewmember Hennadiy Otychko to the territory controlled by Ukraine. Therefore, the return of others is also possible. Alexander Bortnikov, whom I sent a letter, should contribute to this," Denisova wrote.

As reported, on October 16, a crewmember of the YaMK-0041 vessel detained in Crimea, Hennadiy Otychko, arrived in Ukraine.
