A significant fire broke out at the Bashneft oil refinery complex in Ufa, Russia, following explosions that residents reported hearing in the early hours of 3 March.

Ukraine intensified its long-range drone attacks against the military and fuel facilities within Russia, aiming to disrupt fuel and ammunition supplies crucial for the Russian military. Russia’s economy also heavily relies on its oil and gas sector, so by targeting oil refineries, Ukraine attempts to exert economic pressure on Russia.

Surveillance footage captured an explosion at 2:38 a.m. local time, after which flames engulfed portions of the Bashneft oil refinery, according to Russian telegram channel Astra.

The Russian Ministry of Emergency Situations (MChS) confirmed the incident but did not specify its cause, initially stating that the fire occurred “near the incineration furnace.”

“Employees of the Russian Ministry of Emergency Situations have contained the fire on the territory of the Ufa Oil Refinery in Ufa,” the regional MChS stated in an official communication. “There is no threat to residents of nearby areas.”

Ukrainian Osint analysts who geolocated the footage claim the fire damaged the L-24-7 unit and oil storage facilities, reportedly including two RVSP-3000 vertical steel tanks and main supply pipelines. They further allege a third RVSP-2000 tank detonated.

While the Ministry of Defense announced the destruction of seven unmanned aerial vehicles (UAVs) overnight, their statement made no mention of Bashkiria, the region where Ufa is located.

In a later update, MChS Bashkortostan reported: “The open fire on the plant territory has been extinguished. No excess of harmful substances has been recorded near the enterprise.” They also suggested the incident was related to “the technological process,” though provided no further details.

The head of Ukraine’s Center for Countering Disinformation, Andrii Kovalenko, characterized the Ufa refinery as having “strategic importance for the Russian army,” noting that it produces aviation and diesel fuel used by Russian military forces.

Kovalenko stated that the Bashkortostan region ranks among Russia’s top five oil refining centers, with the Ufa complex processing approximately 20 million tons of crude annually.
