I was in doubt, and that’s why I went with the general/chat forum rather than news. However, the incident could be just as easily a pro-Ukrainian stunt to distract from real issues regarding Ukrainians in Poland and make Russia look bad, as much as it could be something the Kremlin cooked up.
I didn’t see anything in the normal Polish news sources I frequent so I figured this was not the story.
If it is from the Hindustan Times you should have a pretty good idea that it is likely to be fake news.
