As far as the airport I concerned, the Minsk Protocol called for UK-Rebel forces to disengage, with Kiev withdrawing heavy equipment to line 15 kilometers away.

After the heavy fighting stopped, the Right Sector refused to honor the agreement, and moved it’s own and Nat Guard (Which are not Army-controlled) forces, including armor, in to hold it.
Lots of videos on Youtube of them claiming credit for it, and celebrating the “Retaking” of the airport, just after the cease-fire.
The Wikipedia entry contains nothing to support your claim. The airport lies outside Russia’s area of control as depicted there. If there is anything concrete that supports your claim, please provide it.
As for the video of Zakharchenko that you posted, if ever proof was needed that Putin has installed mafia government in the Donbas, there it is. He looks, talks and acts like the Putin installed gauleiter that he is.
