Illegally convicted Ukrainian film director Oleh Sentsov, who has been on hunger strike in a Russian penal colony since May 14, 2018, has been transferred to the hospital for a "scheduled" health checkup.

"In connection with a scheduled health checkup, convicted Oleh Sentsov on September 28 was taken to Labytnangi municipal hospital, where he underwent additional examination and received medical advice," the press service of the Federal Penitentiary Service's department in Yamalo-Nenets Autonomous Okrug told UNIAN.

The Russian authorities continue insisting that Sentsov's health is stable.

As UNIAN reported earlier, Sentsov was arrested in 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 town of Labytnangi, Russia's Yamal.

He went on hunger strike on May 14, demanding that Russia free all Ukrainian political prisoners. Sentsov's cousin, Moscow-based journalist Natalya Kaplan says his condition is critical and things are "catastrophically bad."
