Ukrainian filmmaker Oleh Sentsov incarcerated in Russia has stopped his hunger strike that began in mid-May, Federal Penitentiary Service (FSIN) Deputy Director Valery Maximenko told Interfax on Friday.

"True, he has stopped his hunger strike. The best nutrition specialists of Moscow have developed a special diet to bring him out of the hunger strike," Maximenko said.

A number of media outlets reported the end of Sentsov's hunger strike earlier.

"I am grateful to everyone involved, including our [FSIN] doctors, Labytnangi hospital physicians, and lawyers who encouraged him to live and told him that life goes on. Our doctors, specialists were the ones who persuaded him [to live] at the end of the day. He chose life," Maximenko said.

In August 2015, the North Caucasus District Military Court sentenced Sentsov, who was detained in Crimea in 2014, to 20 years in a high-security penitentiary on counts of forming a terrorist group in Crimea.

Sentsov went on hunger strike on May 14, 2018, and demanded that all Ukrainian incarcerated in Russia be released.

Prison doctors kept Sentsov alive with nutrient blends while he was on hunger strike.
