A court in Crimea has sentenced a leader of the peninsula’s Tatar community to eight years behind bars for inciting civil unrest, the Krym.Realii news website reported Monday.

The Crimean Supreme Court found Akhtem Chiigoz guilty of provoking clashes between pro-Russian and pro-Ukrainian activists outside a government building in Simferopol on Feb. 26, 2014.

Chiigoz’ attorney Nikolai Polozov told supporters gathered outside the courthouse on Monday that the verdict “is against the entire Crimean Tatar population,” according to Krym.Realii.

Chiigoz, deputy head of the Tatar representative assembly known as the Mejlis, was detained in late January 2015.

The fact the court recognized Chiigoz as a citizen of Ukraine “gives us a chance to talk about his extradition,” leader of the Mejlis Refat Chubarov said at a press conference in Kiev.

Ukraine’s Foreign Ministry spokeswoman told Krym.Realii that Kiev plans to seek Chiigoz’s release through appeals to the international community. “Ukraine will continue to fight for all citizens who fell victim to the Russian occupational authorities,” she said.
