Ukraine's Ministry of Foreign Affairs (MFA) demands that Russia free 64 Ukrainian political prisoners who are imprisoned in Russia and Russian-occupied Crimea.

"At least 24 Ukrainians are political prisoners in Russia alone and over 40 in occupied Crimea. We once again demand that Russia free the hostages," MFA spokesperson Mariana Betsa wrote on Twitter on May 20.

As UNIAN reported earlier, Russian authorities in Crimea detained some Crimean Tatars early in May 2018. Among the detainees were members of political prisoner Nuri Primov's family. Primov, 38, is accused of involvement in Hizb ut-Tahrir, an organization which is legal in Ukraine, but which Russia has declared a 'terrorist' one.

Ukraine's MFA protested against the detentions and announced plans to go to international courts.
