MOSCOW, April 3 (RAPSI) – The Federal Security Service, or FSB, announced on Friday that a branch of the Ukrainian far-right nationalist movement Right Sector in the Republic of Crimea was added to a terror list.

Russian Supreme Court ruled in November to blacklist Right Sector and Ukrainian People's Self-Defense, known as UNA-UNSO, as terrorist organizations and ban them from operating on the territory of the country.

The blacklist published by the FSB comprises 23 organizations, including ISIS, al Qaeda, Hizb ut-Tahrir, the Taliban (Students of Islamic Knowledge Movement), the Muslim Brotherhood, and the People’s Congress of Ichkeria and Dagestan.

Russia’s Prosecutor General’s Office reportedly requested in mid-March that communications regulator Roskomnadzor block access to websites that promote the activities of Ukrainian nationalist organizations, including the Right Sector. 

Four members of the movement accused of plotting attacks in Simferopol, Yalta and Sevastopol were arrested last May, according to the FSB.

Moreover, Russian prosecutors launched a criminal investigation into Dmitry Yarosh, a leader of the Right Sector movement.

He was placed by Interpol on its international wanted list last July after he had been charged with inciting terrorism and arrested in absentia in Russia.
