Kiper said the attack injured two people and damaged more than 30 vehicles.
Ukraine's air force said it destroyed 26 of the 38 Iranian-made Shahed drones deployed by Russia.
In the Kherson region in southern Ukraine, officials said the Russian attack overnight injured at least four people.
The governor of Russia's Kursk region, which borders Ukraine, said Tuesday that a Ukrainian drone dropped an explosive on an electricity substation, knocking out power to several villages.
