The Russian Investigative Committee's main investigations department has opened a criminal case against Ukrainian parliamentarians Yuriy Bereza, Andriy Levus, and Ihor Mosiychuk on charges of public calls for terrorist activities or public justification of terrorism (Russian Criminal Code Article 205.2), Investigative Committee spokesman Vladimir Markin told Interfax.

Bereza, Levus, and Mosiychuk have made statements justifying the crimes committed in Grozny, Chechnya, on December 4, 2014 and called via mass media for committing similar crimes on Russian Federation territory, Markin said. "Within the framework of the criminal case, the investigation has issued relevant instructions on declaring the suspects wanted," he said.

"These so-called deputies are probably poorly aware or are completely unaware of the efficiency of the Russian law enforcement system's work. Especially for them and for those who could feel the temptation to repeat their remarks, I'd like to point out that none of those who have committed terrorist attacks and similar crimes on the Russian Federation territory has managed to evade responsibility: some of them have already been convicted and some destroyed in offering resistance. This very fate is also facing those calling for such crimes on Russian territory, wherever they are," Markin said.

Head of the Chechen republic Ramzan Kadyrov earlier called for opening a criminal case into remarks by the Ukrainian parliamentarians in support for the gunmen responsible for killing 14 policemen in Grozny.

Kadyrov said in an Istagram post on Friday evening that he had earlier suspected Ukrainian nationalists of providing "financial or other support to the remnants of terrorists in the Caucasus."

"Now no doubts are left," Kadyrov said, adding that he implied primarily Ukrainian parliamentarians Bereza, Levus, and Mosiychuk. "Considering the new circumstances, I have ordered taking exhaustive measures for detaining the said individuals, as well as another criminal, Isa Munayev, and bringing them to Chechnya," he said on Instagram.

Kadyrov also suggested that the role of these Ukrainian parliamentarians in the Thursday events in Grozny should be analyzed. "If someone thinks that it is allowed to support terrorism with impunity, they are making a great mistake," he said.

It was reported earlier that Bereza and Levus had been included in the Ukrainian Verkhovna Rada's national security and defense committee. Bereza, the commander of the Dnipro-1 special police task force, belongs to the Popular Front faction. Levus, also a member of the Popular Front faction, served earlier as deputy chief of the Ukrainian Security Service. Mosiychuk is a former Azov battalion deputy commander for public relations and belonged to the Radical Party of Oleh Liashko's faction.
