Ukrainian drones struck two oil refineries in Russia early Tuesday, triggering fires at facilities in the Krasnodar and Bashkortostan regions, according to local authorities.
The attacks mark the latest escalation in Kyiv’s campaign against Russian energy infrastructure, targeting critical processing hubs deep within Russian territory.
The strikes come just days after Ukrainian forces hit a refinery in Yaroslavl on July 6, signaling a sustained effort to degrade Russia’s refining capacity.
Regional officials in Bashkortostan confirmed visible smoke and damage, though the immediate operational impact on output remains unclear.
With no official production data yet released, markets are likely to price in the risk of further supply constraints.
Brent crude futures moved higher in early trading, reflecting renewed concerns over Russian supply reliability.
