"And when in Minsk many things had to be agreed with these representatives [of the illegal armed groups], why it was only they? That is my question. It seems to me that this [involving IDPs in talks] will be fair," Zelensky said.

"And I am in dialogue with them [the IDPs] ... And I would very much like that in Minsk, I think it's right that in Minsk, where there are representatives, supposedly representatives, of the occupied part of Donbas, that a few other representatives join them, those who fled (from Donbas). They are real IDPs and also residents of the occupied Donbas," Zelensky said.
