As UNIAN reported earlier, Pavlo Hryb was in August 2017 abducted from Belarus by the Russian FSB security force and consequently illegally arrested in the Russian Federation.

Trumped-up charges were pressed against the young man, who was 19 at that moment, under Article 205 of the Criminal Code of the Russian Federation (an act of terrorism). Russian investigators accused Hryb of allegedly plotting a terrorist attack at a school assembly in Sochi.

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

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

On July 3, 2018, the court in Rostov-on-Don ruled to continue holding Pavlo Hryb in custody until December 20.
