UNITED NATIONS, April 28. /TASS/. Ukraine’s denazification will be completed and those responsible for crimes will be punished, Sergey Leonidchenko, senior adviser to Russia’s Permanent Representative to the United Nations, said on Wednesday.

"Torture centers are really unthinkable in the 21st century and there is a lot of evidence, a lot of eye-witness evidence that SBU (Ukraine’s Security Service - TASS) has established a secret torture center at the Mariupol airport, which is cynically dubbed as a ‘library,’" he said at an Arria-formula meeting of the United Nations Security Council. "The center was set up in 2014, when the Azov nationalist battalion was housed in Mariupol. This center was used for torturing, raping and killing "books," as neo-Nazis called the center’s prisoners - civilians suspected of unloyalty to the Kiev regime."

"I assure you that those responsible for this and other atrocious crimes will be brought to trial. No one will evade punishment. The denazification of Ukraine will be completed," he stressed.

On February 24, Russian President Vladimir Putin announced a special military operation in response to a request for help by the heads of the Donbass republics. He stressed that Moscow had no plans of occupying Ukrainian territories, but aimed to demilitarize and denazify the country.
