Brent crude futures climbed in early trading as a massive drone attack struck an oil depot in Armavir, a city in southern Russia's Krasnodar Region.
The strike ignited a blaze covering approximately 800 square meters at the storage facility, according to local authorities cited by TASS.
This incident marks the latest escalation in Ukraine's campaign against Russian energy infrastructure, following similar strikes on facilities in the Tver Region and near Moscow earlier in the week.
The attack on the Armavir depot adds to growing concerns about the vulnerability of Russia's fuel logistics network.
While the immediate volume impact from a single depot fire is likely limited, the recurring nature of these strikes introduces a persistent risk premium into global oil markets.
Traders are increasingly pricing in the potential for broader supply disruptions as Ukrainian forces expand their reach into southern Russia, a key hub for fuel distribution and export pipelines.
This development follows a series of strikes that have already disrupted refining capacity and storage reserves in western Russia.
