Ukrainian drones forced Rosneft's Kuybyshevsky oil refinery in Samara Oblast, Russia, to halt oil processing on 10 June, Reuters reported. The strike puts all three plants in the Rosneft Samara refining hub out of full operation at the same time.
With Ukraine's deep strikes accelerating into the summer season, each new plant taken out compresses Russia's repair window and hardens the fuel-supply squeeze on its military logistics.
Reuters confirms processing halt at both primary units
Reuters cited two industry sources to confirm that processing stopped at both AVT-4 and AVT-5 after the strike. Each unit has a nominal processing capacity of about 73,000 barrels of crude oil (10,000 metric tons) per day. The hits caused damage and subsequent fires at both.
Samara Oblast Governor Vyacheslav Fedorishchev claimed a massive overnight drone attack injured three people and caused "damage to several industrial facilities."
An earlier report on 10 June described fires at the Kuybyshevsky refinery after the strike.

Plant size and output
Kuybyshevsky's 2024 crude oil throughput was 4.7 million tons, equal to 94,400 barrels a day, Reuters reported. That year's output included 0.8 million tons of gasoline, 1.4 million tons of diesel, and 1.3 million tons of fuel oil. Nominal capacity stands at 7 million tons per year. The plant is one of the largest oil refining facilities in the Volga region. It also supplies fuel for the Russian army.
The Kuybyshevsky plant belongs to Rosneft's Samara refining cluster alongside Novokuibyshevsky and Syzran. Syzran's operations have been suspended since a 21 May drone attack, Reuters reported, and the plant has yet to resume. The Novokuibyshevsky plant shut down after an 18 April strike and now operates at reduced throughput. Ukraine has hit all three plants in the cluster in less than two months.
The Kuybyshevsky plant was also previously hit in January 2026, August 2025, and in March 2024. The earlier strikes damaged equipment and forced production cycles to stop.
Same night: Cheboksary defense plant struck
The same night, Ukrainian forces also struck the VNIIR-Progress plant in Cheboksary, Chuvashia, which was previously hit on 5 May. The factory makes "Kometa" antennas that protect Russian drones from electronic warfare. It also makes satellite receivers for GLONASS, GPS, and Galileo systems. Ukraine's General Staff said such modules are used in Shahed-type drones, Iskander and Kalibr missiles, and aerial bombs.
Meanwhile, today saw a strike on the Afipsky refinery in Krasnodar Krai.

Afipsky oil refinery burns again as Ukrainian drones return to Krasnodar Krai
By May 2026, Ukrainian drones had taken six of ten Russian refineries hit during that month offline. Russian media counted 24 of Russia's 33 largest refineries struck since 2022. Only the Omsk and Angarsk plants east of the Urals remain untouched so far.
Ukrainian drones struck four vehicular bridges at Crimea's northwestern entrance overnight on 11 June 2026, quisling official Vladimir Saldo claimed. The strikes are part of Ukraine's most recent mid-range strike push—now at its fourth day—reaching every road corridor between Crimea and mainland Ukraine. The same night, drone attacks also rolled across Sevastopol, Bakhchysarai, Saky, and other Crimean sites.
Russia depends on the Crimean land corridor to push fuel, ammunition, and replacements to its forces in occupied southern Ukraine. Ukrainian mid-range drones operating under the military's LogisticsLockdown program have steadily shrunk that corridor's reliability since May. Ukraine has now struck all three major connection points between occupied Crimea and mainland Ukraine within four days, damaging some bridges and destroying others.
Four bridges damaged at the Armiansk isthmus
Saldo, the Russian-installed head of occupied Kherson Oblast, named the four targets on his Telegram. They include the automobile bridge in the Perekop-Armiansk area and a bridge near Stavky, Kherson Oblast. Two more bridges near Myrne and Preobrazhenka span the North Crimean Canal. Saldo stated all four spans sustained damage.

Three Crimean northern choke points hit in four days
Ukraine struck the Chonhar bridge on 7 and 9 June, closing Russia's main road link to occupied Crimea, yet the Russians reportedly installed a pontoon bridge next to the severely damaged crossing. On 10 June, Ukrainian drones hit the bridge from Henichesk to Arabat Spit. With both routes fully or partially shut, Russia had rerouted traffic through Armiansk and Perekop — the very corridor struck overnight. DeepState analysts noted that Ukrainian strikes on the bridges are an important part of the blockade of occupied southern Ukraine.

Not only an entrance, but also targets across the peninsula
Russia's occupation governor, Mikhail Razvozhayev, claimed 32 drones were shot down over Sevastopol between 22:00 and midnight. He claimed the drones fell near Sevastopol Bay, Cape Fiolent, and Balaklava. The city declared two air alerts during the night and the morning.
Monitoring Telegram channel Krymsky Veter reported machine-gun fire in Pishchane at 21:40 and in Andriivka shortly after, citing subscribers.
"At 21:40 a machine gun started firing in Pishchane, at 21:48 a machine gun started in Andriivka, after which an anti-aircraft gun fired a couple of bursts," the channel wrote.
Detonations followed near Cape Fiolent, in Sevastopol, and later in Bakhchysarai. By morning, Krymsky Veter reported explosions and shooting in Saky.
Russia's Defense Ministry claimed the destruction of 330 drones over Russia and the occupied territories in the same overnight period.
Update
The First Assault Brigade shared the footage of the strikes:
Videos emerged of some of the Ukrainian strikes on bridges linking occupied Crimea to occupied Kherson Oblast
Ukraine's 1st Assault Brigade, 475th Assault Regiment, and SBU's Alfa reportedly took part.
Russia has begun moving gasoline to its frontline units in occupied Ukraine in convoys of civilian cars, the Ukrainian defense outlet Militarnyi reported. Soldiers filmed themselves loading jerrycans into ordinary trunks, an improvised workaround after Ukrainian drone strikes made fuel tankers too risky to run. Russian forces are also disguising army trucks as civilian vehicles along the supply route to occupied Crimea.
This comes amid Ukraine’s ongoing “Logistics Lockdown,” a campaign by several Ukrainian military branches and the Security Service to target Russian fuel, logistics, and other supplies across occupied territories, at depths of up to 200 km.
Soldiers filmed the fuel run themselves
A video on the Exilenova+ Telegram channel showed Russians describing a convoy of passenger cars assembled to carry one metric ton of gasoline, Militarnyi reported. A man off-camera says the cars left the city of Kizilyurt in Dagestan, Russia, on the local head's orders, with the fuel destined for Russian units in occupied Tokmak, Zaporizhzhia Oblast. The footage shows jerrycans filling the trunks:
Besides the fuel, the drivers carried 1.5 million rubles ($20,900) to buy another batch of gasoline. Fuel keeps Russian frontline positions running: generators power electronic-warfare systems, charge batteries for reconnaissance and strike drones, and run communications gear in dugouts and observation posts.
Disguised trucks and a strained supply line
Russian forces have also begun disguising army trucks as civilian transport because of Ukrainian drone attacks deep in the rear. In northern Crimea, monitors spotted a freshly painted blue Ural truck driven by a man in civilian clothes, still carrying military plates, its oversized body posing as a dump truck.
The command of Russia's Dnepr grouping ordered mass use of civilian vehicles to move fuel along the route linking Rostov-on-Don with occupied Crimea, the Krymsky Veter monitoring project reported. That improvisation tracks the M-14 corridor, now within Ukraine's deepening drone range.

Why Russia is improvising
Ukraine's Defense Forces have intensified drone strikes on logistics trucks and fuel tankers on the roads from Russia to occupied Crimea. The attacks have already forced the occupiers to limit cargo traffic through the occupied part of Kherson Oblast toward the peninsula, and Russia has closed stretches of its own land corridor to keep them clear of strike drones.
Ukrainian drones set a major oil depot ablaze near the Russian Black Sea port of Novorossiysk overnight on 7-8 June 2026, in a strike confirmed by Ukraine's Unmanned Systems Forces (SBS). Residents reported a string of blasts and heavy smoke over the Grushovaya storage site, which feeds Russia's busiest oil-export port. Ukrainian forces hit two more targets in southern Russia the same night.
Ukraine has spent the past year pushing its deep-strike campaign further into Russia, hunting the refineries, pipelines, and export ports that turn crude into the cash funding the invasion. Each hit on this Black Sea network forces costly repairs and brief loading halts, and steady Ukrainian success deep in Russia's rear, alongside a steadier front, is shifting how the West reads the war.
Drones spark a blaze at Novorossiysk's oil hub
The strike came before dawn. Residents of Novorossiysk, in Russia's Krasnodar Krai, reported about 50 blasts, then heavy smoke over the Grushovaya oil depot. Operators of the SBS's 1st Separate Center, working with Special Operations Forces (SSO) and other units, confirmed the hit. Ukraine's General Staff also confirmed the strike and said a fire broke out, with damage still being assessed. Russian officials claimed no one was hurt.

NASA's FIRMS satellite service detected abnormal heat at the site at 02:48 on 8 June. Ukrainian Telegram channel Exilenova+ began reporting the attack around 3 a.m., posting photos and videos of fire in the mountains above the city. OSINT Telegram channel Falcon insight pinpointed the location. Russian news Telegram channel ASTRA confirmed the burning tank farm from eyewitness footage shot about 11 km away.

What the Grushovaya depot feeds
The Grushovaya site is a transshipment depot for the Sheskharis terminal. Chernomortransneft runs it, under Russia's state pipeline monopoly Transneft. It sits in the Grushovaya Balka tract beyond the Markotkh Ridge, about 12 km from Novorossiysk. The tank farm holds more than 1.2 million m³ of fuel across dozens of tanks, on a site of about 212 hectares. SBS called it one of the largest oil-product stores in the Caucasus.

Novorossiysk is southern Russia's biggest oil-export hub, the Moscow Times reported. The port ships up to 700,000 barrels a day, and its terminals moved 19.8 million tonnes of oil products in 2025. That trade feeds Russia's budget, which bankrolls the war on Ukraine. The port has become a recurring target in Ukraine's strikes on Russia's Black Sea oil logistics.
Volgograd and a coastal radar also hit
The same night, Ukraine's General Staff said its forces struck the Krasny Yar oil-pumping station in Volgograd Oblast, where a fire broke out. Volgograd governor Andrei Bocharov claimed the blaze came from falling drone debris at the Zhirnovsk pumping station and was quickly put out, the Moscow Times reported. Ukrainian forces also hit a Russian radar station near Kabardinka in Krasnodar Krai, according to the General Staff.

Not the first strike on Novorossiysk's oil chain
Ukrainian forces have hit this infrastructure before. Ukrainian defense outlet Militarnyi reported that drones struck the Grushovaya depot on 23 May 2026, when fire spread across much of the site. Strike drones also hit the Sheskharis terminal on 6 April, damaging oil-metering systems and shut-off valves at the loading berths. ASTRA said the wider complex was attacked in early March, early April, and on 22 May.
Ukraine's drone strikes on the highways that feed Russian forces in occupied southern and eastern Ukraine are disrupting Russian logistics and will likely bite deeper in the near future, according to the Institute for the Study of War (ISW). The campaign is also rattling Russia's pro-war online community, where bloggers have begun turning their anger on the Kremlin's own military leadership. Russian forces are already rerouting and disguising convoys to keep supplies moving.
Ukraine's drone war has dragged the fight off the trench line and into Russia's rear, where fuel and transport increasingly decide how long Moscow can keep its invasion supplied. If Ukrainian crews keep the main arteries under watch, Russia faces a slow squeeze on its rear and the political cost of admitting those roads are no longer safe.
Ukraine's drones now own a key supply road
Ukraine's 3rd Army Corps said on 31 May that its drones had won "fire control" over five occupied cities. All five sit on or near the M-04 highway: Luhansk City, Starobilsk, Alchevsk, Bryanka, and Kadiivka. In plain terms, Ukrainian crews can now strike traffic on that road.
Ukrainian drone strike zones layered over Russia's southern supply network. FPVs reach roughly 20 km from the front, Hornets and other AI-assisted drones to 150 km, and FP-1 and FP-2 long-range drones to 200 km. The M-14 highway (Rostov-on-Don to occupied Crimea) and H-20 (branches north from Mariupol into Donetsk Oblast) both fall inside the deeper rings. Russian authorities have closed the M-14 to civilian traffic. The Ukrainian segment of the same highway, between Kherson and Mykolaiv, was closed by Ukrainian authorities in August 2025 after Russian drones turned it into a "human safari" killing ground. Map: Euromaidan Press.
A Ukrainian drone operator argued the M-04 matters more to Russia than the better-known M-14. The M-14 links Rostov Oblast to occupied Crimea. The M-04 begins near Moscow and reaches Rostov-on-Don before carrying on to Russia's Black Sea coast and into the Caucasus. It feeds occupied Crimea, southern Ukraine, and Luhansk Oblast through the Russian towns of Millerovo and Kamensk-Shakhtinsky. It also supplies Donetsk Oblast through Novoshakhtinsk in Rostov Oblast.

The two highways connect, and Ukrainian forces are also hitting the H-20 road that joins them through Donetsk City. ISW assessed that the strikes will likely generate "even more profound cascading effects" across Russia's rear. The effort extends Ukraine's wider push to drive deep strikes further behind the front.
Russia bans buses and repaints its trucks
The strikes are already forcing changes on the ground. Leonid Pasechnik, the Russian-installed head of occupied Luhansk Oblast, issued a decree on 6 June. It bars regular bus and coach services on the section of the highway crossing occupied Luhansk.

Ukrainian Mariupol mayoral adviser Petro Andriushchenko reported on 7 June that Russian forces had changed their Mariupol–Berdiansk route. They now use local coastal roads instead of the M-14. ndriushchenko said the troops are passing army vehicles off as civilian, recoloring the tarpaulins over each cargo bed and spraying the trucks white. ISW assessed the detours will likely slow Russian supply runs as Ukraine keeps hunting vehicles.
Russia's war bloggers turn on the Kremlin's generals
Ukraine's strikes are landing in Russia's information space too. Russia's pro-war military bloggers are voicing discontent and panic over the campaign.

Ukraine doubles deep strikes beyond 50 km as “Logistics Lockdown” shifts priority deeper into Russia’s transport nodes and rear logistics chains
A pro-war blogger and former Storm-Z assault-unit instructor complained on 7 June that Ukraine is now striking factories and defense plants deep inside Russia while degrading Russian air-defense radars and systems. He blamed bureaucracy and state-corporate infighting for Moscow's failure to respond, and separately complained that Russia cannot read Ukraine's battlefield trends and underrates its capabilities. Other bloggers piled on: one claimed fuel shortages were stoking panic in occupied Crimea, while others faulted the Russian Defense Ministry and top general Valery Gerasimov for not striking Ukrainian logistics, especially the Dnipro River bridges.
ISW found the complaints are escalating, and that the strike campaigns are becoming "points of neuralgia" in Russia's ultranationalist crowd. It noted the discontent feeds on Russia's poor battlefield results, rising casualties, and economic strain. Even before this, Russia's war bloggers had turned on the Kremlin's commanders over inflated victory claims.
Commander of Ukraine’s Unmanned Systems Forces, Robert “Madyar” Brovdi, says Russian losses reached 1,006 killed and 1,090 wounded during the first six days of June, as Ukrainian drone forces continued strikes against targets on and beyond the front line.
The commander of Ukraine’s Unmanned Systems Forces published the figures on 7 June alongside an update on overnight operations targeting Russian logistics and infrastructure in occupied territory and inside Russia.
More than 2,000 casualties reported in six days
Brovdi said Russian forces suffered a combined 2,096 killed and wounded between 1 and 6 June.
He described the losses as equivalent to the combat strength of a full Russian assault brigade lost within a single week.
The commander also used a railway comparison to illustrate the scale of the casualties, saying the losses would add the equivalent of 20 refrigerated and medical railcars to Russia’s “one-way ticket” train over the six-day period.
Drone strikes target rear-area infrastructure
According to Brovdi, Ukrainian forces also struck 26 targets overnight on 7 June across occupied parts of Luhansk, Donetsk, Zaporizhzhia, and Crimea, as well as Russia’s Bryansk Oblast.
He said Ukrainian units destroyed an air defense system and damaged three locomotives, two railway fuel tanks, four electrical substations, and six telecommunications towers. The strikes also disrupted the movement of military cargo toward the front, according to the statement.
Earlier on 7 June, Ukrainian Special Operations Forces reported strikes on the Semikolodezyanska oil depot in Yedi-Quyu and a maritime fuel terminal in Feodosia. Ukrainian officials said the operation was intended to reduce Russia’s logistical and economic capacity to sustain military operations in occupied territory.
The reported targets fit a broader Ukrainian effort to degrade Russian logistics networks, transport infrastructure, and support systems operating behind the frontline.
Ukraine says it doubled the number of successful strikes on Russian targets more than 50 kilometers behind the front line in May under the “Logistics Lockdown” program, which prioritizes attacks on transport networks, fuel infrastructure, depots, and other systems supporting Russian military operations.
