In neighboring Crimea, Sergey Aksyonov, the Moscow-installed head of the peninsula, said three people were killed and two others injured in overnight Ukrainian drone attacks.
In Russia's Belgorod region, acting Governor Alexander Shuvayev said four people were killed and 17 injured in Ukrainian attacks over the previous 24 hours, including three children.
