"The sentencing of Mr Umerov is a serious violation of his human rights, another example of persecution of the Crimean Tatar community, and a further and clear illustration of the severe deterioration of human rights on the Crimean peninsula, as most recently documented by the United Nations High Commissioner for Human Rights in his report published earlier this week," the EU Delegation to Ukraine posted the EU's statement on its Facebook page.

The European Union does not recognize the illegal annexation of the Crimean Peninsula by the Russian Federation and therefore does not recognize this "court" and its sentence.

This conviction is in breach of international humanitarian law and the European Union expects it to be reversed.

"The European Union is unwavering in its support for the territorial integrity and sovereignty of Ukraine. We reiterate that all illegally detailed Ukrainian citizens on the Crimean peninsula and in Russia must be released immediately," the statement said.

As UNIAN reported earlier, Russian-controlled Simferopol District Court on September 27 sentenced deputy chairman of the Russian-outlawed Mejlis of Crimean Tatars Ilmi Umerov to two years in a settlement colony.
