Russia says it intercepted 376 Ukrainian drones overnight, with strikes triggering fires at refineries and fuel depots in southern Russia
Ukraine has beefed up its efforts in recent months to hinder Moscow's financial capabilities in its war, targeting energy infrastructure in retaliation for strikes.
Moscow's air defence units intercepted unmanned aerial vehicles around the country, including over the capital region, the defence ministry wrote on the state-run Max platform.
Drone attacks also sparked fires at oil facilities in southern Russia, authorities said, with debris from an unmanned aerial vehicle causing a blaze at a refinery in Krasnodar Krai, while fires broke out at two petrol storage facilities in the Azov district.
Fragments of drones fell across a town in Krasnodar Krai's Severskaya district, where the Ilsky refinery is located, including in the courtyard of a home, the regional operational headquarters posted on Telegram.
The Ilsky refinery, with a capacity of around 138,000 barrels per day, has been attacked several times before.
In Azov, emergency services were at the scene, regional governor Yury Slyusar wrote on Telegram.
In Russia's Rostov region, fires were being extinguished at two fuel depots and at the Taganrog sea port, Governor Yury Slyusar said on Telegram.
Authorities reported no casualties.
The attacks come after Russian President Vladimir Putin acknowledged last month that the country was suffering fuel shortages after repeated Ukrainian strikes.
Kiev calls the attacks fair retribution for Russia's near-daily barrages on Ukrainian civilians and energy infrastructure since Moscow's February 2022 offensive.
