Russian human rights activist Zoya Svetova called to write letters to Ukrainian filmmaker Oleh Sentsov more often. Svetova appealed the public on her Facebook page. 

Although the human rights activist notes that Sentsov himself does not like writing letters and rarely responds to them.

“But I think it's still very important," she said.

According to her, Sentsov reads two books a week and learned English, but he cannot find anybody to practice it in the Yamal prison.

“The temperature outside is 20 degrees below zero. The snow has been already lying for three months. In general, he is still sitting there, just like the rest of the innocent Ukrainians, in particular - it's a shame for us all. We must demand from our authorities, from both Ukrainian and Western ones, to facilitate their release," Svetova called.

Reportedly, the Ukrainian political prisoner Oleksandr Kolchenko asked people who write letters to him, to report more about what is happening in Ukraine, Russia, Belarus and the world as a whole. 

He notes that he does not know what to write to strangers, as nothing happens in his life in fact.
