Head of the Center for Release of Prisoners Volodymyr Ruban confirmed the conversation with the lawyers and said that Russia agreed to exchange Sentsov and Kolchenko for servicemen Aleksandrov and Yerofeyev.
Ruban informed that the Center received an offer to exchange Sentsov for Yerofeyev at a meeting in Minsk, but the Ukrainian side proposed to exchange "two for two": two Russian commandos for Sentsov and Kolchenko.
The negotiators from the Russian side agreed to such an exchange, he said.
"The exchange cannot be carried out immediately before the sentence is imposed on Aleksandrov and Yerofeyev. Then there will be exchange upon a mutual agreement of the parties - they will serve their sentences at home. Under certain guarantees, the diplomats will exchange not the hostages, not prisoners of war, but convicts and each of them will be brought to his country where one should have still receive a pardon," Ruban said.
However, according to him, there is also the possibility of the exchange of the Russian special forces operatives for Nadiya Savchenko. Such an exchange may take place any time if there is political will of both sides. But still it can take place after the verdict.
"The Donetsk side submits up to 1,200 names of people to the Ukrainian negotiating group in Minsk, who they believe are in custody in Ukraine. About 500 of them are militants recognized by the Donetsk side - we have got them. They propose to exchange them "all for all" or under some other format, e.g.: exchange all of our 13 people, whom we consider to be political prisoners in Russia, for this thousand people. And Poroshenko will be like the Israeli Prime Minister, who exchanged a corporal for 1,027 people," Ruban said.
