Ukrainian drones reportedly struck a major oil refinery in the Russian region of Krasnodar Krai overnight on Sept. 7, Russian Telegram channels reported.
Russian Telegram media channel Exilenova+, citing resident accounts, reported a large blaze emanating from the Ilsky Oil Refinery, around 2:15 a.m.
Photos and videos circulating on social media appeared to show a large fire rising from the refinery.
The Kyiv Independent cannot immediately verify the reports.
Ukraine's military has not yet commented on the reported attack.
Ukraine has intensified long-range strikes against Russian energy facilities, targeting refineries and depots to cut into Moscow's war funding.
Located roughly 500 kilometers (311 miles) from Ukrainian-controlled territory, the refinery is among the largest in southern Russia, producing over 6 million tons of fuel annually.
Kyiv has previously struck the Ilsky Oil Refinery on multiple occasions — most recently on July 7 when a drone struck one of the facility's technological workshops, a source in Ukraine's military intelligence (HUR) told the Kyiv Independent.
Krasnodar Krai, a strategic region along Russia's Black Sea coast, has increasingly come under Ukrainian drone attacks as Kyiv extends the range of its strikes deep into Russian territory.
