Smoke and fire were reported at a major oil refinery near Moscow on July 10, according to monitoring channels on Telegram.
The cause of the blaze has not been confirmed, and no official statement from Russian authorities or the facility operator has been issued to verify the extent of the damage or operational impact.
Brent crude prices ticked up in the session as traders assessed the potential for renewed supply constraints.
The development adds to a growing list of incidents targeting Russian energy infrastructure, which has become a focal point for market volatility.
While the immediate impact on global supply remains unclear, the recurrence of attacks near the capital heightens uncertainty around domestic fuel availability in Russia and its potential spillover effects on regional exports.
This incident follows a series of strikes on Russian refineries in recent weeks, including a significant attack on a facility in the Nizhny Novgorod region that supplies fuel to Moscow and surrounding areas. Those earlier strikes contributed to a worsening domestic fuel shortage in Russia, a crisis that has spread beyond localized disruptions. The pattern of attacks has kept energy markets on edge, with Brent crude previously rising as fears of supply disruption escalated.
The fire at the Moscow-area refinery underscores the persistent risk to Russian energy infrastructure as Ukraine intensifies its cross-border operations.
