Russian forces, meanwhile, carried out 71 air strikes and 17 attacks from rocket salvo systems on the positions of Ukrainian troops and populated areas, the message said.
The regional military administration in Kherson said Russian forces dropped explosives on residential areas the region, injuring a 48-year-old man in the village of Kozatske.
Russia reported a drone attack in the southern region of Bryansk. The region's governor said one person was injured in the attack, which also damaged windows and the roof of an administrative building.
The governor, Aleksandr Bogomaz, said on Telegram that the incident occurred in the town of Trubchevsk. Bogomaz earlier reported that a village in the region had been shelled by Ukrainian forces, damaging three homes.
Earlier on September 30, a huge fire erupted at an oil pipeline in the western Ukrainian region of Ivano-Frankivsk.
"Nine people were injured," regional Governor Svitlana Onyshchuk said. "According to preliminary information, two children and three adults are in critical condition, with numerous burns," she added.
The blaze caused an oil spill spanning 100 square meters before it was extinguished. Footage shared on social media showed thick clouds of black smoke billowing out over a village, while firefighters worked to tackle the blaze.
The cause of the fire was not immediately clear, but local media outlets reported there had been a powerful explosion.
Moscow and Kyiv said earlier they had shot down dozens of airborne attacks over their respective territories overnight as the furious pace of nighttime air assaults continued.
Russia's Defense Ministry said its forces had intercepted all nine missiles that it claimed Ukraine fired into its western Belgorod region.
It said the attack was with Uragan multiple-launch rocket systems.
In Ukraine, air alert sirens blared in cities and towns across the southern and eastern parts of the country around 1:30 a.m. local time on September 30, followed by explosions far from the front lines including in the central region of Vinnytsya.
At least one explosion was also reported in Kramatorsk, where the Ukrainian military's rear base is located for the frontline eastern region of Donetsk.
A spokeswoman for Ukraine's Southern Defense Forces said on Ukrainian television that Russia had launched more than 20 kamikaze drones apparently bound for southern and central Ukraine overnight but that around 20 of them were destroyed.
Spokeswoman Natalya Humenyuk said many of the attacks appeared to target areas south of the Black Sea port of Odesa and that "the enemy's priority is still the Danube, in particular, the port infrastructure."
Authorities in Vinnytsya, a central Ukrainian city used extensively for humanitarian shipments since the start of the 19-month-old invasion, ordered an evacuation from the area around an infrastructure site that they said had been struck in the Russian attack.
Regional Governor Serhiy Borzov and the head of the local administration in the Vinnytsya-area town of Kalynivka confirmed the incident but did not provide details.
Humenyuk, the Southern Defense Forces spokeswoman, said the fire in Vinnytsya had been put out and the situation was no longer critical there.
