The Ukrainian Foreign Ministry has demanded that Russia give permission for the medical examination of Ukrainian Pavlo Hryb, who is illegally held in Russia, by experts of the Ukrainian Health Ministry.

"The consul visited Pavlo Hryb today [on November 20]. Given his condition, we again demand that Russia grant permission for his examination by specialists from the Ukrainian Health Ministry," Foreign Ministry spokesperson Mariana Betsa wrote on her Twitter page on Monday.

Ex-Ukrainian State Border Guard Service official Ihor Hryb said on August 28 that Russian special services had abducted his 19-year-old son Pavlo during a visit to Gomel, Belarus, where he went on August 24 to meet a girl whom he had met and talked to only on social-networking sites. It was agreed that Pavlo would return the same day. After he failed to return the next day, Ihor Hryb travelled to Gomel to look for him.

He said that in Belarus he had learned that Pavlo was on a Russian list of wanted persons in connection with a terrorist attack, and that a search had been initiated by the Russian Federal Security Service's Directorate for the Krasnodar region in Sochi.

It was reported on September 7 that Hryb was in a detention facility in Krasnodar, Russia.

On September 15, Pavlo Hryb's sister Olha Hryb said her brother was transferred from jail to hospital. According to her, neither Ukrainian consuls, nor Ukrainian doctors were allowed to see the detainee.

Ukrainian doctors arrived in Russia on October 12 to examine Hryb, who is being held in a pretrial detention center in Krasnodar and does not receive the necessary medical care, but the Russian side didn't allow them to examine the Ukrainian.

On October 18, the Oktyabrsky District Court of Krasnodar (Russia) extended detention term for Ukrainian Pavlo Hryb until January 4, 2018.

The next hearing of the Krasnodar court is scheduled for December 24.
