Press secretary of the Ukrainian Foreign Ministry Mariana Betsa emphasized that the illegally convicted Ukrainian film director Oleh Sentsov has been on a hunger strike for 100 days already.

"Sentsov has been on a hunger strike for 100 days. A terrible count. Human life is the highest value. We demand that the Russian Federation immediately release Oleh," she wrote on Twitter.

The Foreign Ministry also appealed to Ukraine's partners and international organizations to increase pressure on Russia to release Ukrainian political prisoners.

UNIAN memo. Sentsov was arrested in the Russian-occupied Crimea in spring 2014, and in August 2015 he was sentenced to 20 years in prison following an unfair trial where he faced "terrorism" charges stemming from his opposition to Russia's occupation of Crimea.

He has been serving his term in a penal colony in the distant town of Labytnangi, Russia's Yamal.

Sentsov began his hunger strike on May 14, 2018, in protest against the politically motivated jailing of dozens of Ukrainians in the Russian Federation.
