Three people were killed and one injured during Ukrainian airstrikes in Russia’s Belgorod region, regional authorities reported.
Earlier, Russian news agency RIA cited the Russian Ministry of Defense stating that 53 Ukrainian drones were shot down by Russian air defenses overnight.
The day before, another Ukrainian strike reportedly destroyed an oil refinery in Russia.
In recent months, Russian refineries have been targeted by Ukrainian forces, as oil and gas sales remain a major source of revenue for Moscow.
