The Ukrainian political prisoner in Russia, Stanislav Klykh, is in a psychiatric hospital, a Ukrainian consul will try to visit him on July 11-12, the Ukrainian parliament's ombudsman Liudmyla Denisova said.

"I've just spoken by phone to Tamara Klykh, the mother of Stanyslav Klykh. Stanislav's mom confirmed that currently her son is in psychiatric hospital...Stanislav was treated for something, he is feeling better, but one can see from his eyes that he is very ill indeed. Tamara Ivanovna said that the information provided by the Russian ombudsman to media outlets, about Stanislav Klykh feeling well, is outdated," Denisova wrote on Facebook on Thursday.

She expressed concern that Klykh had asked for children's books and at a meeting with his mother two months ago he "also kept talking about early years all the time."

"Currently Tamara Klykh cannot travel to her son, herself being very ill, she has big health problems. She is already 75 years old. The Ukrainian consul telephoned to her and said she would try to see Stanyslav on July 11-12, if they let her in. The Consulate will keep things under control and hopefully Stanyslav's whereabouts will become known," Denisova said.

The ombudswoman added that Klykh's mother wanted her to visit Stanyslav because she does not trust the information she receives about him from various sources.

"I will be asking the Council of Europe's Human Rights Commissioner Dunja Mijatovic once again to facilitate my visit to our political prisoners in Russia, primarily those who are on hunger strike and in an alarming health condition: Stanyslav Klykh, Volodymyr Balukh, Oleh Sentsov, Emir-Usein Kuku," Denisova said.
