Ukrainian Foreign Ministry has said that just Russian authorities are completely responsible for life and health of Ukrainian parliamentarian and pilot Nadia Savchenko.

"Russian Federation continues ignoring Nadia Savchenko's immunity as a delegate of Parliamentary Assembly of the Council of Europe and thus, frankly speaking, breaches the commitments undertaken, confirming political not a legal character of the trials [carried] against MP Savchenko. The separate attention should be drawn to a considerable worsening of Nadia's state of health, which was caused by her forceful hunger as a protest against despotism of so-called Russian justice, as well as absence of a qualified medical aid and unsatisfactory conditions of her detention. Under such conditions Russia and only Russia bears responsibility for Savchenko's life and health," reads a ministry's comment posted in Ukrainian by the press service on Tuesday.

The diplomatic establishment once again expressed "a resolute protest regarding a continuous cynical judicial harsh treatment of Ukrainian citizen in Russia."

"A special indignation aroused by a constant demonstrative neglecting of the elementary procedural norms. The Nadia's rights are systemically violated: the court refuses to look into the official documents received by the lawyers from Ukraine, refuses to listen to the witnesses mentioned by the defenders, turns down an appeal to add the materials of the defenders to the criminal case: protocols of the questioning of the witnesses, investigation materials over the fact of kidnapping of the Ukrainian citizen, examinations of the video materials, which contain fair evidence of her innocence," reads the document.

The ministry demanded from Russian Federation "to stop tortures over Savchenko and other illegally detained citizens of Ukraine – political prisoners of Russia, and to immediately release them and ensure their returning to Ukraine."

Savchenko since July 2014 has been keeping into Russian custody under charges with involvement in the killing of Russian journalists in the east of Ukraine.
