France and Germany back Kyiv in a need to reach an agreement to free citizens of Ukraine kept as political prisoners in Russia and Donbas, Ukrainian Foreign Minister Pavlo Klimkin said.

"Today's meeting got started with a talk about Nadia Savchenko since today she celebrates her birthday. I'm glad that both my German and French colleagues supported the necessity of making progress towards the release of political prisoners and hostages kept in Russia and Donbas," he told journalists in Berlin following the "Normandy Four" meeting.

Klimkin said that at today's meeting he handed letters from mothers of illegally detained Ukrainians by Russia to his German and French colleagues.
