Fine. Now Ukraine will be free to execute the captured Wagner Group and Chechen mercenaries by the same standard.
The Wagner group are mercenaries in every meaning of the word.
Unpaid foreign volunteers in UAF are inducted into the UAF and subject to Geneva Convention and laws of war.
The (illegal, unrecognized) Donbass paramilitary will regret this.
First, they probably have only 50-60 Russians in custody and they are unlikely of mercenary group. Chechens are regulars belonging to the Russian national guards. Second, Ukraine is an aspiring Europeans nation and doesn’t have death penalty.
Ukraine has apparently had their own approach for dealing with captured Russians, for some time now...
