People hold placards with an appeal to boycott the Russia World Cup 2018 football tournament in front of the Russian Embassy in Kiev on June 14, 2018, during a rally to demand the release Oleg Sentsov and other Ukrainian political prisoners in Russia. Ukrainian film director Oleg Sentsov, who is serving a 20-year prison sentence in Russia, will have spent a month on hunger strike in jail demanding that Russia release his fellow Ukrainians who he says are being held as political prisoners. To draw Western attention to Moscow's role in the four-year conflict in eastern Ukraine, Ukrainian artist Andriy Yermolenko made a series of graphic drawings that have become popular on Facebook. / AFP PHOTO / Genya SAVILOV
