They look like chechens to me chechens/dagestani/abkhazia people from caucausia. Those who or their family members commited war crimes in grozny in teh 90s/20s. They fled their country and resettled all over ex soviet states. amongst them is ukraine. This is actually the people kadyrov spoke about.
They are always the first people to flee when shit goes south. Proper ukrainian refugees would probably leave when this war is going to be over. but these ones are here to stay forever. until Germany falls apart then they move to the next best place.
