The Normandy Four is the format of talks that involves Ukraine, Germany, France, and Russia. According to Kuleba, diplomats continue seeking ways to return Savchenko home. Besides, negotiations on release of other Ukrainian political prisoners are ongoing. "Russia has assumed the attitude that Ukrainian political prisoners may be released only after they are sentenced by Russian courts. So, we need to wait for verdicts in [a few more cases of political prisoners]. Russia simply simulates administration of justice as all the cases are trumped-up," Kuleba said. The meeting of foreign ministers of Ukraine, Germany, France and Russia is planned for May 11th.
