MOSCOW, April 11 (RAPSI) – Russian Prosecutor General’s Office on Thursday has transferred to Interpol the materials required for the international search of Ukrainian ultranationalist Right Sector leader Dmitry Yarosh, Prosecutor General Dmitry Chaika told the journalists on Friday.

Yarosh stands accused in Russia of publicly endorsing extremism and terrorism in connection with an appeal he is suspected of having made to North Caucasus militant commander Doku Umarov. Specifically, Yarosh stands accused of asking for help with carrying out terror attacks on Russian soil.

Umarov, the self-proclaimed head of a secessionist group in the North Caucasus, has claimed responsibility for several terrorist attacks in Russia. He recently made international headlines after threatening to attack the Winter Olympics in Sochi.

Moscow's Basmanny District Court ordered Yarosh's arrest in absentia on March 11. Soon afterwards he appealed the order.

The parliament of Crimea, which recently voted for its independence from and its reunification with Russia, banned nationalist party Svoboda (Liberty) and ultra-nationalist political movement Right Sector, which is headed by Yarosh.
