Russian Human Rights Commissioner Tatyana Moskalkova or her regional representatives will visit Ukrainian citizens Mykola Karpiuk and Stanislav Klykh, who have been convicted in Russia, Mykhailo Chaplyha, a spokesman for Ukrainian Human Rights Commissioner Valeria Lutkovska, said on Hromadske Radio.

Lutkovska and Moskalkova reached agreement on the matter at a meeting on June 21, Chaplyha said.

"Either she [Moskalkova] personally or her regional representatives should visit them [Karpiuk and Klykh]. The situation should be assessed as impartially as possible, with the understanding that politics should be put aside, from the human rights standpoint. If there are reports on torture, competent agencies should be alerted, so as to conduct an efficient investigation, and also pay attention to procedural rights," Chaplyha said.

Lutkovska managed to secure the release of 18 Ukrainian convicts from Crimea, although Ukraine's list contained about 40 such people, he said.

The Chechen Supreme Court sentenced Karpiuk to 22.5 and Klykh to 20 years' imprisonment on May 26. The sentence stipulates that Karpiuk will spend the first 10 years and Klykh the first 9 years in jail, and then the two will serve the rest of their sentences in a strict security penitentiary. A jury earlier found Karpiuk and Klykh guilty of the charges brought against them.

The Russian investigation claim that Klykh and Karpiuk had been members of the extremist organization Ukrainian National Assembly-Ukrainian People's Self-Defense (UNA-UNSO) and fought for armed units of the self-proclaimed republic of Ichkeria against Russian federal forces in 1994-1995. In particular, they were charged with fighting Russian troops in Grozny, including in the area of Minutka square and near the presidential palace.
