"From what we know of human rights defenders and some Ukrainian citizens - the relatives of servicemen captured near Ilovaisk and transferred to Russia, three dozen of people are meant," he said.
According to Feigin, there are soldiers of different "paramilitary formations", members of the Armed Forces of Ukraine and regular units among those 30 Ukrainian prisoners held in Russian prisons.
"They are kept in different detention centers. This is confirmed by a number of human rights organizations that are involved in dealing with this matter," he said noting that in this case the Ukrainian Ministry of Foreign Affairs shall refer to the Russian Foreign Ministry to contact the investigating committee in respect of persons who are involved in criminal proceedings applied to Savchenko as well, and request to submit this list of the Ukrainian citizens.
According to him, success in Savchenko's case will establish precedent and will promote the release of other Ukrainian prisoners of war.
