"As of today, Stanislav Klykh is in a very serious condition. He is a person involved in the so-called "case of Chechen militants" of Ukrainian origin... Stanislav Klykh is a person who has gone mad because of the torture, which was applied to him during the arrest and during the preliminary investigation. It is absolutely unclear how this person will be in prison, where he must be sent in the near future," she said.

According to Svetova, it is necessary to conduct him a forensic psychiatric examination in the Serbsky State Scientific Center for Social and Forensic Psychiatry and to send him to Ukraine as soon as possible, putting him in a psychiatric hospital.

"He's really a terrible victim of Russia's repressions against Ukrainian citizens. He was detained by accident when he arrived from Ukraine to the Russian city of Orel," she added.

At the same time, according to Svetova, a forensic psychological examination of Klykh showed that he was mentally healthy and could participate in the trial, according to

As UNIAN reported earlier, on May 26, 2016, Judge of the Supreme Court of the Republic of Chechnya Vakhit Ismailov ruled to sentence Ukrainian citizen Mykola Karpiuk to 22.5 years in a strict-regime penal colony, another Ukrainian citizen Stanislav Klykh was sentenced to 20 years in prison.

Ukraine has made Russia dozen requests for their extradition. The last one was sent in August.

The appeal against conviction of Karpiuk and Klykh will be considered by Russia's Supreme Court on October 26.
