A short distance from Karkiv. Are obviously operating in Russian territory. Attacks on railway, depots, refineries, and industy in the Russian neighbouring Oblast have increased.

Curiously how did Ukraine get behind any lines.

These perhaps haven't been as offensive? But the border is becoming breached by forms of counter warfare.

No, it isn't that counter offensive. But instead is a means of incited and sponsored combat within Russia.

False Flag, unlikely. Attacks are being made outside of this incident. Yesterday or not too long back these groups identified themselves as oppositional Russian militias. But they have direct links to Ukraine, and have stated are acting on their behalf, thorough their goals, also by acquiring various weapons and personnel who are fighting Russia, for Ukrainian territory, despite supposedly identifying as Russian. Clearly they're sponsored and propagated by Ukraine? They're trying to incite separation from Russia, and are attacking Russia, in tit for tat comedy. Only Ukraine could think of something so utterly daft, where it has taken all this time to instigate. Instigation has been occurring after Ukraine reinforced Karkiv prior to Bakhmut?

Result of this incident and attacks causes further escalation.

I don't know anything about it. It hit the news yesterday, western media dismissed it, distancing it being from Ukraine. Except when Ukraine attacks targets, railways, refineries, depots, industry in Belgorod oblast it has praised it, but look at these insurgents?
