Czech humanitarian organisation People in Need has launched a campaign to release the Ukrainian film director Oleg Sentsov from Russian prison. Photos are to be shared on Instagram with a call for the release of the filmmaker. People in Need will then print them and send them to the prison where Sentsov is jailed.
Oleg Sentsov, who is 39, was arrested in 2014 during a protest against Russia's annexation of Crimea. He was sentenced to 20 years in jail by a Russian military court in 2015 on charges of terrorism.
The filmmaker has been on hunger strike since May 14, saying he will stop only if all Ukrainian political prisoners held on the Russian territory are released. Politicians and other public figures all over the world have been campaigning for his release.
