MOSCOW, October 14. /TASS/. A fighter of punitive battalion Dnepr accused of killings of civilians in the troubled Ukrainian south-east was convoyed to Moscow for a psychological and psychiatric expertise at the clinic, spokesman of the Russian Investigative Committee Vladimir Markin told TASS.

“At the present time defendant Litvinov who had recently been convoyed to Moscow is to undergo a complex psychological and psychiatric expertise and was brought to a Moscow expert institution for the expertise. As in the case with Savchenko, this expertise is a standard procedure according to Russian legislation applied for defendants accused of grave and particularly heinous crimes and people who participated indirectly in armed conflicts,” Markin said, noting that this expertise mainly sought to find whether a defendant is sane or insane and whether he is able to participate in the trial.

According to Markin, Sergei Litvinov's victims included women and children at four locations in south-eastern Ukraine's Luhansk region.

Confessions from Ukraine's Dnepr battalion fighter at a Moscow psychiatric clinic helped reveal irrefutable evidence of crimes by gunmen of Ukraine's National Guard, the extremist Right Sector movement and military servicemen, he added.

Russian investigators found violations of the United Nations' Convention on Prevention and Punishment of the Crime of Genocide, one the UN's first acts adopted in 1948, and of other international provisions condemning genocide, Markin said.

According to Investigative Commitee spokesman, unidentified individuals from Ukraine's political and military leadership, its armed forces, National Guard and the Right Sector gave orders to kill Russian speakers living in the self-proclaimed Donetsk and Luhansk people’s republics, the spokesman said.
