A Ukrainian drone strike has forced the Saratov Oil Refinery—a major facility in southwestern Saratov Oblast owned by state-run Rosneft—to halt crude oil intake, Bloomberg reports, citing people familiar with the matter.

The 10 August attack triggered explosions and a fire on-site, abruptly halting operations at a plant capable of processing around 140,000 barrels of crude per day. Analysts warn that if the shutdown persists, Russia’s domestic gasoline supplies could face pressure just as seasonal demand climbs.

Escalation before high-stakes Alaska talks

The strike comes just five days before a planned 15 August summit in Alaska between US President Donald Trump and Russian President Vladimir Putin. The White House has said the meeting could expand into a trilateral peace negotiation if Ukrainian President Volodymyr Zelenskyy attends, though Kyiv’s participation remains uncertain.

Despite the diplomatic push, fighting has intensified. Both sides are exchanging waves of drones and missiles, with Ukraine stepping up strikes deep inside Russian territory while Russia continues to bombard Ukrainian cities.

Part of a wider campaign against Russian energy infrastructure

The Saratov facility is the latest in a string of Ukrainian drone attacks on Russian refineries this month. On 2 August, strikes disabled the Ryazan and Novokuybyshevsk refineries. Five days later, Ukraine targeted the Afipsky refinery in the Krasnodar Krai, followed by a reported strike on a plant in Russia’s Komi Republic, some 2,000 kilometers from Ukraine.

The Saratov plant’s position along the Volga River makes it a strategic hub for both regional fuel distribution and exports—raising the stakes of its prolonged closure.

The Ukrainian Armed Forces General Staff has confirmed that Ukrainian drones struck the Saratov oil refinery in Russia during a nighttime operation, the military command announced.

“Tonight, the Unmanned Systems Forces of the Armed Forces of Ukraine, in cooperation with other components of the Defense Forces, struck the Saratov oil refinery (Saratov Oblast, Russia),” the General Staff reported.

According to military officials, the drone strikes resulted in explosions and fire at the facility. The Saratov refinery processes up to 7 million tons of oil annually and serves as a key fuel infrastructure facility supplying petroleum products to occupying forces.

The General Staff said that Ukrainian defense forces continue operations aimed at reducing Russia’s military-economic potential to force an end to its aggression against Ukraine.

“Every targeted facility on the territory of the Russian Federation involved in supporting its criminal war against Ukraine brings us closer to a just peace,” the military command stated.

The attack occurred on the night of 10 August, when drones targeted the refinery in the Russian city of Saratov, triggering a large-scale fire at the facility.

Russian officials reported drone strikes on the Saratov Oblast overnight on 10 August, with a local oil refinery apparently sustaining damage, Governor Roman Busargin said.

The Saratov oil refinery processes up to 7 million tons of crude oil annually, producing vital motor fuels and other petroleum products that supply a significant part of Russia’s domestic market and military needs, having served as a crucial logistics hub since World War II.

The governor confirmed damage at an industrial facility following the drone assault. Busargin claimed debris from a downed drone fell in a residential courtyard, prompting evacuations to a temporary shelter organized at a nearby school. According to the governor’s account, there was one fatality and several injured.

Local residents told the Russian propaganda outlet ASTRA that the Saratov oil refinery came under attack.

Russia’s Defense Ministry reported intercepting 121 drones over Russian Bryansk, Belgorod, Voronezh, Stavropol, Kaluga, Tula, Rostov  and Ryazan oblasts and occupied Crimea during the night.

The Saratov Oblast has faced regular drone attacks. On 1 July, Ukraine’s General Staff confirmed that Defense Forces struck the Saratovgorsintez oil refinery in the Saratov region. Explosions occurred in Saratov and Engels on 5 July, where a Russian airbase is located from which aircraft launch strikes against Ukraine.
