Several dozen activists gathered at the Brandenburg Gate in Berlin to commemorate the fifth anniversary of Russia's occupation of the Crimea. Russia annexed this part of Ukraine in violation of international law. The international community reacted with sanctions against Russia.
The participants also demanded the release of hundreds of political prisoners from Russian custody.
Vira Savchenko, the sister of Nadiya Savchenko, a Ukrainian military pilot, who was initially imprisoned in Russia and is now in prison in Ukraine, is also taking part in the rally.
