Kyiv, Ukraine – Russia and Ukraine have intensified their aerial battles, striking at each other’s vital energy and transportation infrastructure, as Moscow pushes ahead with its ground offensive in eastern Ukraine in the fourth year of the war. The escalation comes as Russia also confirmed the testing of a hypersonic missile, underscoring the growing sophistication of the conflict.

Russia’s Ministry of Defence said on Sunday that its air defences intercepted 361 drones, four guided aerial bombs, and rockets from a US-supplied HIMARS system overnight. On the other side, the General Staff of the Ukrainian Armed Forces reported the downing of a ballistic missile and 164 drones of varying types.

One of the main targets of Ukraine’s overnight strikes was the Kirishi oil refinery in Russia’s Leningrad region, one of the largest refineries in the world’s second-largest oil-exporting nation. Ukraine said the attack was a “successful strike,” reporting explosions and fire at the site. However, the extent of the damage remains unverified. Regional governor Alexander Drozdenko stated that three drones were destroyed in the Kirishi area, and a fire caused by falling debris was quickly extinguished without casualties.

The Kirishi refinery, operated by Surgutneftegas, processes about 17.7 million metric tons of crude annually (roughly 355,000 barrels per day), placing it among Russia’s top three refineries by capacity. Ukrainian drones have targeted the site before, with a smaller strike in March causing minor damage. Kyiv has intensified attacks on Russian oil facilities in recent months, arguing that these refineries directly fuel Moscow’s war effort.

The escalation is unfolding as US President Donald Trump declared he is prepared to sanction Russia further, but only if NATO allies agree to completely cut off purchases of Russian oil and impose parallel sanctions. The debate highlights growing international pressure on Moscow, even as it seeks to maintain oil revenues amid increasing disruption.

In a separate incident in Russia’s Leningrad region on Sunday, two freight trains derailed in different locations. Governor Drozdenko reported that one train driver was killed, and railway traffic was severely disrupted. While the cause of the derailments has not been confirmed, the incidents add to the atmosphere of instability across Russian infrastructure.

Drone warfare has become a defining feature of the conflict. More than three years into the full-scale invasion, Ukraine has relied on drones to push deep into Russian territory, while Russia continues to deploy swarms of drones into Ukraine. The threat has even spilled over into NATO territory, with Polish fighter jets recently deployed to shoot down Russian drones that crossed into Polish airspace.

According to Russia’s Defence Ministry, at least 80 Ukrainian drones were shot down overnight across Russian regions, Crimea, and the Sea of Azov. Despite these interceptions, Ukraine’s growing ability to target critical oil facilities has begun to impact Russia’s domestic fuel market.

In recent weeks, gasoline shortages have hit several regions across Russia, with long queues forming at fuel stations. The Kremlin has introduced rationing measures and, in an attempt to stabilize supplies, imposed a ban on gasoline exports until September 30, with partial restrictions set to remain until the end of October.

As both sides continue to escalate strikes on energy infrastructure, the battle over oil refineries and fuel supplies has become an increasingly critical front in the war, with direct implications for Russia’s economy, Ukraine’s resistance strategy, and global energy markets.
