Ukraine
Was that just a normal car that got hit?
Yes.
So this was clear MLRS type rockets.
Russia said, about 3 min after the end of the salvo, they were UAF Vampyre 122mm rockets.
However, the max range of that rocket is 36km. Belgorod is 40km from closest border area and they control it. ( near Vovchansk in Kharkiv oblast )
So there is some doubt that it was UAF rockets.
Belgorod is a large city, so if these strikes were in the southern part of city, (closer to border ) then MAYBE.
But that would mean that UAF drove the launcher within 1 km of border region that now is HEAVILY defended with detection systems, artillery and drones.
I haven't seen any photos of geolocation nor debris to prove or disprove this claim. And not putting false flag past Russia.
Ukraine doesn't have enough supply to waste on randomly firing at civilian targets nor the lack of decency RuAF possesses.
However this strike below by RuAF yesterday may have prompted a reply.
But I'll wait to see concrete evidence.
