He said: "Alas, I have bad news. The negotiation process came to deadlock. I will not go into details, but in my opinion it is necessary to change something in this matter.
"Over the past month we released 42 people. This month we have been asked not to interfere with the big exchange.
"Despite the fact that we were doing our best to prevent the negotiations from being ruined, they eventually stalled.
"We should either play politics or liberate the guys."
In turn, one of the militant leaders Alexander Zakharchenko said that the prisoner exchange with Kyiv has been suspended, according to Gazeta.ru.
"We send the lists of prisoners of war, and we receive lists of random people. We want to take back the military, our soldiers and friends. In addition they send us relatives of the fighters: mothers, wives, children," Zakharchenko said.
