Kremlin's young political prisoner, a Ukrainian national Pavlo Hryb, who is being accused in Russia of plotting a "terror act," is finally able to read letters sent to him, after he was transferred from Krasnodar to a pre-trial detention facility in Rostov-on-Don.

According to his father, Ihor Hryb, Pavlo had not been allowed to see letters before the transfer, Hromadske reports.

"As soon as he was transferred to Rostov, he began to receive [letters]," his father said.

In addition, the administration took away Pavlo's personal notes.

At the same time, the father of the political prisoner has no information about his son's state of health.

As UNIAN reported earlier, in August 2017, Pavlo Hryb was abducted from Belarus by the Russian FSB security force and consequently illegally arrested in the Russian Federation. Trumped-up charges have been pressed against the teenager under Article 205 of the Criminal Code of the Russian Federation (an act of terrorism).

Russian investigators accused Pavlo Hryb of allegedly plotting a terrorist attack at a school assembly in Sochi.

Pavlo Hryb is diagnosed with portal hypertension, which requires daily intake of necessary medications and a special diet, the lack of which could become fatal.

Russian authorities do not allow access of Ukrainian doctors to examine the political prisoner's health.

On July 23, 2018, the court in Rostov-on-Don, Russia, returned the indictment to prosecutors on the case of a Ukrainian youngster Pavlo Hryb and extended his arrest until October 22, 2018.
