Russia is illegally holding 405 Ukrainian citizens, including 44 servicepersons and 30 women, in concentration camps and torture chambers located both in Russian Federation and occupied territories. Ukrainian Parliament Commissioner for Human Rights Lyudmyla Denisova said this during a solemn sitting of the Parliament on the occasion of the Constitution Day on Monday. Denisova noted that the armed aggression of the Russian Federation and the temporary occupation of the Autonomous Republic of Crimea and the city of Sevastopol and a large part of Donbas led to the violation of Ukraine's territorial integrity and encroached on its independence. Thus, the ombudsperson said, the state regrettably cannot guarantee constitutional rights and freedoms in the occupied territories. Our compatriots are forced to survive under the laws of natural selection of the aggressor state which eradicates not only everything Ukrainian but also human dignity, Denisova said. The Commissioner emphasised that 405 Ukrainians are being held in concentration camps and torture chambers. Currently, 405 citizens of Ukraine, including 44 servicepersons and 30 women, are held in concentration camps and torture chambers in the Russian Federation and in the occupied territories, the ombudsperson reported. Denisova stressed that the occupier deprived the prisoners of the right to freedom, personal security, legal protection but it cannot deprive our compatriots [Ukrainians] of freedom of thought and conviction of hope to return to Ukraine. According to her, ensuring the Constitution of Ukraine to work for everyone in the country, must be the common duty of parliamentarians.
