jolihokistix,
In fact, in Russian media there indeed was some mentioning of Ukraine but only in the context that "explosives to make such IEDs are easily accessible on the open market. E.g., the components of that particular explosives found on the drones captured are produced at many chemical plants such as ... including Shostka plant in Ukraine". There was no mentioning that they came out of this specific plant and no blame on any particular group.
