The only relevant news I've found is https://function.mil.ru/news_page/country/more.htm?id=12321737@egNews, but we're quite far from that area, so I don't think it's related. And the shooting sounds like bursts of fire, while you'd expect tank exercises to involve targeting one tank at a time (although if the tank has a rocket launcher, they could be firing bursts from it).
So, you end up wondering what's going on and whether something has happened.
