So far Ukrainians are saying this. And that it was them who shot it down.
There is no confirmation from Poland nor verification of any other kind about it.
I'll keep an eye on it.
Even if it happened, my suspicion is there will be radio silence (in fact the more silence the more likely it is to my mind. If its not true there will be a strong rebuttal). But nothing will happen until something is actually hit on the NATO side of the border.
No strategic benefit.
