Ukraine's military said on Wednesday it struck an S-300 anti-aircraft missile system based in Russia's southern Rostov region overnight.
Kyiv's General Staff said the attack took place near the settlement of Novoshakhtinsk, and that S-300s had been used to attack civilian infrastructure in Ukraine.
"Explosions were observed at specified targeting points," the General Staff said in a statement. "The accuracy of the strike is being assessed."
Rostov governor Vasily Golubev said air defence forces had destroyed a Ukraine-launched missile over his region, but Russia's defence ministry made no mention of the incident in its daily statement on destroyed air weapons.
