(QHA) -

Increasing pressure on Crimean Tatars is unacceptable, Turkey's foreign minister has said.

Mevlut Cavusoglu was speaking at the 24th African Union Summit in the Ethiopian capital Addis Ababa, where he said Crimean Tatars have been facing pressure since the the regions's unification with Russia.

Cavusoglu’s comments come after Deputy Chairman of the Crimean Tatar Mejlis Ahtem Ciygoz was detained on Thursday by the Russian Federal Investigative Committee on suspicion of organizing "mass disorder" Feb. 26, 2014 when Crimean Tatars held a rally, showing their support for Ukraine.

Crimea joined Russia in March, following a local referendum on the region's status. The U.S. and EU denounced the referendum as illegitimate, as the region was occupied by Russian soldiers at the time.

Although Turkey is among the countries opposed to Russia’s annexation of Crimea, and one that defends the territorial integrity of Ukraine, Turkey did not implement the Western-led economic sanctions imposed on Russia.
