Drone Strike Ignites Fire at Major Russian Oil Refinery in Yaroslavl

A substantial fire broke out at the Yaroslavnefteorgsintez refinery in Yaroslavl, central Russia, early Friday after a drone strike targeted the facility. Residents reported hearing multiple explosions before observing a bright glow and thick smoke emanating from the refinery area. Videos circulating online depict a large blaze engulfing parts of the plant.

The Yaroslavnefteorgsintez refinery, operated by Slavneft, ranks among Russia's top five oil-processing plants. Monitoring groups suggest the facility was likely hit, though Russian authorities have yet to confirm any damage.

In a separate incident, debris from a downed drone struck a residential building in Tver, injuring six adults and one child. Acting regional governor Vitaly Korolev stated that residents assisted neighbors in evacuating as a fire broke out on a lower floor. Twenty-two people, including five children, were relocated to a temporary shelter at a local school.

These events occurred less than 24 hours after Ukraine launched its most extensive combined drone attack of the conflict, targeting energy production facilities and military airfields across western and central Russia. The operation aimed to disrupt Russia's energy infrastructure, with all five targeted energy sites catching fire following the strikes.

Additionally, a long-range strike hit an offshore oil platform in the Caspian Sea, operated by Lukoil. The platform, located approximately 1,500 kilometers from potential Ukrainian launch sites, was struck multiple times by long-range drones, resulting in a fire and halting production. No injuries were reported, but firefighting efforts continued into Thursday.

These developments underscore the escalating use of drone warfare targeting critical energy infrastructure in the ongoing conflict.
