MOSCOW, August 9 (RAPSI) - Ukraine’s ombudsman Lyudmila Denisova has asked Russian human rights advocates to discuss any terms of exchange of film director Oleg Sentsov sentenced in Russia to 20 years in prison for organizing a terrorist group in Crimea, a statement published on her Facebook page reads.

Denisova applied to Russia’s ombudsman Tatiana Moskalkova and Chairman of the Presidential Council for Human Rights Mikhail Fedotov in order to “save Oleg Sentsov”, who went on a hunger strike 87 days ago.

The North Caucasus District Military Court sentenced Sentsov to 20 years in prison in August 2015. Another defendant in the case Alexander Kolchenko received 10 years in prison.

Investigators found that Sentsov started a terrorist group in Crimea, a branch of the Right Sector movement banned in Russia. He was allegedly promoting Crimea’s secession from Russia.
