The headline is fine, but why are there Polish soldiers in the photo? Author, look closely. The photo shows several men in traditional Polish military uniforms.
The origin of this photo is also easily found on the Internet. Google photo search tells us the following: this is the deportation of Ukrainians by the Polish army from Bialystok region, which after the Second World War went to Poland.
Unfortunately, during the info war, propaganda flows both ways. There were deportations in Stalin era (not just by the Soviets, but also Polish, Germans, Turks, Greeks etc), but calling it an ethnic cleansing when just a few years prior an actual ethnic cleansing of Jews was taking place, is kind of a stretch. This particular photo is probably from the population exchange between the Polish and the Soviet Ukraine.
