I don't think that's how missiles work, but if it's really the same then it was in possession of DNR, wasn't it?
Three weeks ago, a Ukrainian Tochka-U missile flew into Donetsk, they managed to shoot it down, but there were still casualties. In Kramatorsk, they did not even try to shoot down the rocket and the cluster munition went off right in the thick of people at the station.
I think Ukraine just doesn't want civilians to leave Kramatorsk to the east, they want to keep using the tactic of hiding behind civilians as human shields. In this area, a blow to the positions of the Armed Forces of Ukraine from Russia is brewing, there are rumors that a fresh armored corps has been brought up from Kursk.
