Two Russian oil refineries caught fire on 11 August, but the two incidents tell very different stories. In Orsk, in Orenburg Oblast, drones sparked a blaze that Ukrainian monitoring channels quickly linked to Kyiv's long-range campaign. Meanwhile, thousands of kilometers farther east, a Rosneft plant in Komsomolsk-on-Amur burned for reasons that remain unexplained.

A drone strike deep in Orenburg Oblast

Early on 11 August, residents of Orsk reported explosions near the Orsknefteorgsintez refinery, and a large fire soon followed. OSINT analysts at the Telegram channel Exilenova+ reported the strike. By their assessment, the drones flew more than 1,500 kilometers from Ukraine's border to reach Orsk. Preliminary findings pointed to damage at the plant's hydrocracking complex. Modernized in recent years, the unit can process 1.6 million tonnes a year.

Russian officials confirmed the attack, though they did not name the target at first. Orsk Mayor Artem Vorobyov urged residents to stay indoors and away from windows. Orenburg Governor Yevgeny Solntsev, meanwhile, activated the "Kovyor" (Carpet) airspace-safety plan across a 100-kilometer radius. Authorities also imposed temporary flight restrictions at the Orsk airport.

An unexplained blaze in the Far East

Far to the east, the picture is murkier. Around 11:00 local time, residents of Komsomolsk-on-Amur reported a fire near the city's refinery. ASTRA then geolocated the footage to Rosneft's RN-Komsomolsk plant. Notably, Ukrainian analysts cautioned that the fire does not appear to stem from a drone strike. After all, the site sits roughly 6,500 kilometers from Ukraine—far beyond the range of Kyiv's long-range drones. Coverage from the Kyiv Independent, meanwhile, flagged no clear cause.

The plant's press service reported no injuries, as relayed by Russian state agency TASS. Commissioned in 1942, the RN-Komsomolsk refinery has a design capacity of about 8 million tonnes of crude per year. In fact, it supplies more than 60% of the petroleum products across Russia's Far Eastern Federal District. Moreover, it produces gasoline, diesel, marine fuel, and other products for the region.

Ukraine's campaign against Russian oil refineries

The Orsk plant is no stranger to such strikes. Drones previously hit Orsknefteorgsintez on 3 October and 11 November 2025, and again on 29–30 April 2026. Since 2022, Ukraine has widened its deep-strike campaign against Russian oil refineries, fuel depots, and pipelines. Such targets power the Kremlin's army and bankroll the war through oil exports. Increasingly, Russian oil refineries have become the signature target of Ukraine's long-range war. Just the night before, on 10 August, Ukraine's General Staff confirmed a strike on the TANECO refinery in Tatarstan. A fire broke out there, too.

As of publication, Kyiv had not claimed the 11 August Orsk strike. Still, the timing fit a familiar pattern—a long-range campaign aimed at the fuel that keeps Russia's war machine moving.

Drones struck several Russian oblasts overnight into 10 August. A probable strike hit a Nizhnekamsk refinery in the Republic of Tatarstan, while fires spread across occupied Crimea. Local Telegram channels and Ukrainian monitoring groups reported the attacks. Kyiv has not claimed them, and the damage stays unverified.

Thick smoke over the Nizhnekamsk refinery cluster

Residents of Nizhnekamsk reported explosions on the morning of 10 August. Footage online showed drones crossing the city, with dense black smoke above one district, local channels said. Which Nizhnekamsk refinery took the hit stayed unclear. The city hosts two major plants — the TAIF-NK and TANECO complexes.

TAIF-NK processes 7.3 million tons of crude and 1 million tons of gas condensate a year. Its 49 products include AI-92 and AI-95 gasoline, diesel, and jet fuel. TANECO belongs to the Tatneft group. It ranks among Russia's largest and most advanced refineries. Its design capacity exceeds 16 million tons of crude a year.

Ukraine's Defense Forces struck both TANECO and TAIF-NK on 12 June, the General Staff confirmed. Ukrainian units hit the same cluster again in July.

Fires flare in occupied Crimea's Krasnoperekopsk

Explosions rocked Krasnoperekopsk — known in Ukrainian as Yany Kapu — overnight. Numerous fires burned by morning, the monitoring channel Crimean Wind reported. Around 7 blasts sounded between 2 and 3 a.m. Subscribers described a fire behind the railway station in the industrial area.

By the morning of 10 August, NASA's FIRMS satellite system flagged multiple heat signatures there, Crimean Wind said. The hotspots clustered in the town's southern industrial zone. Russian forces store and repair equipment in the area, the channel added.

Drones also crossed Sevastopol. Residents heard aircraft and gunfire near the Balaklava thermal power plant. The Russian-installed governor, Mikhail Razvozhaev, claimed 15 drones fell, mostly over the sea. He admitted, though, that falling debris ignited a forest fire near Inzhir beach and forced a campsite evacuation. A blast in Simferopol briefly cut power around 4 am before supply returned.

Moscow and Rostov cite downed drones

In the capital, Mayor Sergei Sobyanin said air defenses downed 13 drones approaching Moscow overnight. He gave no details on any consequences. Over Rostov Oblast, Governor Yuri Slyusar said more than 70 drones destroyed. Information on casualties and damage was still coming in, he said.

Both counts reflect Russian air-defense claims rather than independently confirmed strikes.

Overnight, Russia's aviation authority Rosaviatsia restricted takeoffs and landings at Begishevo airport in Nizhnekamsk. The curbs also covered 14 other airports, among them Kazan, Ufa, Samara, and Moscow's Domodedovo and Vnukovo.
