Ukraine struck a Russian drone-control relay station and two other military targets in occupied Crimea and the occupied south overnight on 12 August, its General Staff said. Explosions rolled across the peninsula through the night, Sevastopol declared repeated air-raid alerts, and towns across occupied Crimea lost power, according to Ukrainian monitoring channels and Russian occupation authorities. 

Russia launches its attack drones at Ukraine from sites inside Russia and across occupied territory every day, and relay stations let it steer those drones over long distances. Occupied Crimea is the logistical spine of Russia's hold on southern Ukraine, the funnel through which fuel, ammunition, and reinforcements reach the front, and its fixed airfields, power plants, and control stations sit within reach of Ukraine's growing long-range arsenal.

What the General Staff says was hit

Ukraine's Defense Forces struck three targets overnight, the General Staff reported. The first was a ground relay station used to control Geran and Gerbera attack drones near Olenivka in occupied Crimea. The others were a Russian repair unit near Mariupol in Donetsk Oblast and a staging point for an enemy drone unit near Marivka in Luhansk Oblast.

Hitting these sites weakens Russia's ability to command its attack drones, keep its military vehicles running, and sustain its units, the General Staff said. 

Euromaidan Press could not independently verify the strikes and damage.

Russia flies these drones through a chain of ground repeaters, often mounted on mobile-operator towers or similar tall structures, boost the control signal so operators inside Russia can steer Geran and Gerbera drones over Ukraine from hundreds of kilometers away. Kyiv has dismantled similar relay networks before, including one Russia had built on towers and rooftops in Belarus.

Explosions and blackouts across occupied Crimea

Sevastopol declared three air-raid alerts, and the Russian-installed governor Mikhail Razvozhaev claimed Russian forces downed more than 30 drones, with the heaviest activity over the Balaklava district and no one hurt.

The Ukrainian monitoring channel Krymsky Veter reported explosions in Feodosia and Kerch, and drones close to the Kacha and Belbek airfields. Residents reported air-defense activity near major cities.

The channel said explosions sounded near the Balaklava thermal power plant, a mobile gas-turbine station, and a substation in Sevastopol. Power cut out across parts of occupied Crimea, leaving Sevastopol, Simferopol, and several more cities and districts without electricity.

Sea drones, jet drones, and Neptune missiles hit one Russian port in a single night

After the attack, Krymsky Veter's monitoring group reported two large fires near Sevastopol, citing satellite data. One sat by a road junction near the village of Pervomaiske under Balaklava, where a bridge crosses the railway. The other burned near one of the local beaches. The group also logged an already-extinguished fire in the Inzhyr tract that had been reported the day before.

The same night, Ukraine also struck Russia's naval base at Novorossiysk, the fleet's main Black Sea base since late 2023.

Part of the campaign to isolate Crimea

The overnight strikes fit Ukraine's months-long effort to cut occupied Crimea off from the forces and supplies that sustain it. Ukrainian drones have severed road and rail links to the peninsula, left it rationing fuel under rolling blackouts, and pushed the campaign onto the sea by hunting the tankers that supply it. 

On 12 August 2026, Ukraine targeted Russia's main Black Sea naval base and oil terminal at Novorossiysk overnight. Fires broke out at the port's oil and fleet facilities, two of Russia's largest grain terminals stopped work, and debris damaged homes across the city, according to Ukrainian monitoring channels and local Russian authorities. Ukrainian President Volodymyr Zelenskyy confirmed the operation hours later.

Kyiv calls it a "unique operation" on the fleet's last big base

Zelenskyy said Ukraine's Defense Forces hit the Novorossiysk naval base overnight on 12 August. The port city is situated more than 350 kilometers from the front line on Russia's eastern Black Sea coast. The Ukrainian president described the assault as a unique operation against the last main outpost of Russia's Black Sea Fleet.

"Our Palianytsia jet drones, Neptune missiles, and naval uncrewed systems precisely struck the designated targets," he said, adding that hits were confirmed on air-defense positions, piers, and seaport infrastructure.

Fires at the Sheskharis oil terminal and the naval harbor

Ukrainian drones hit the oil terminal and the naval base, the Ukrainian defense outlet Militarnyi reported. Its analysis of NASA satellite fire data placed blazes at the Sheskharis complex, where crude loads onto tankers, and near the naval base and fuel-storage tanks.

Sheskharis is the endpoint of Transneft's main pipelines and a key export point for Russian crude on the Black Sea. Novorossiysk ships 600,000 to 700,000 barrels of oil a day.

The Ukrainian monitoring channel Krymsky Veter said fires broke out near the Sheskharis pier and the military harbor where Black Sea Fleet ships and submarines dock. Russia moved vessels to Novorossiysk after Ukrainian strikes pushed the fleet out of occupied Crimea.

Two grain terminals stop at the world's top wheat exporter

Novorossiysk's two largest grain-handling terminals halted work after the strikes, Reuters reported, citing four industry sources. The world's top wheat seller, Russia sends most of its exports out through Black Sea ports.

The Novorossiysk grain terminal, which can move 8.5 million tons a year, halted work as owner Demetra Holding assessed the damage. NKHP, a terminal handling 7.1 million tons a year, also stopped, its main owner OZK said, adding that no one was hurt. The Ukrainian monitoring Telegram channel Exilenova+ described NKHP, Russia's largest deepwater grain terminal, as one of the sites hit.

The strikes extend Ukraine's effort to deny Russia the grain and oil revenue that funds the war, a mirror of Russia's own summer campaign against Ukraine's ports: as Moscow strikes Odesa's terminals to choke Ukrainian exports, Kyiv works to shut Russia's own.

Russia says its own drone debris damaged homes and killed two

Krasnodar Krai Governor Veniamin Kondratyev claimed several hundred drones attacked the region overnight and that falling debris struck 21 residential buildings and four enterprises in Novorossiysk. He claimed two people were killed, including an eight-year-old child, and 13 wounded across the krai, with about 90 residents moved to temporary shelters.

Novorossiysk Mayor Andrei Kravchenko claimed debris hit six residential buildings, a commercial building, and a construction site, and that there were casualties.

The Russian news Telegram channel Astra reported that a café burned on Sukhumskoye Shosse, across the road from the entrance to the Novorossiysk naval base. Astra also found that a strike damaged School No. 15 near the fleet's ship berths.

Part of a widening summer campaign

The strike fits a broader Ukrainian effort this summer to carry the war onto Russian soil and drain the Kremlin's ability to fight. A day earlier, Ukrainian drones set a Wildberries logistics complex ablaze near Voronezh and hit an oil refinery in Orsk. Overnight on 10 August, drones struck a petrochemical plant in Tobolsk and a refinery in Tatarstan.

Striletska Bay near Sevastopol, once a key base for Russian warships in occupied Crimea, is now nearly empty and used primarily for mooring tugboats and small patrol craft, the Atesh partisan group reported on July 8.

According to the group, Russia now uses the bay mainly for maintenance work and rare anti-sabotage defense drills, having pulled most major vessels from the area.

"Recently, the bay has been practically empty... The degradation of the occupation fleet in Sevastopol is becoming increasingly obvious. Striletska Bay, which previously housed a large number of combat vessels, is now idle." Atesh said.

The remaining combat units are periodically rotated and redeployed in an apparent effort to avoid detection by Ukrainian reconnaissance.

"Every object is under control — no ship will go unnoticed," Atesh said, adding that all ship movements are being tracked and shared with the Ukrainian Armed Forces.

Sevastopol has served as the base for Russia's Black Sea Fleet since the illegal annexation of Crimea in 2014. Repeated Ukrainian attacks using naval drones, missiles, and long-range drones have forced the Kremlin to reduce its naval presence in occupied Crimea.

Ukraine has destroyed several Russian vessels, including the Caesar Kunikov landing ship, the Sergei Kotov patrol ship, the Ivanovets missile corvette, and multiple high-speed landing crafts.

The shrinking Russian presence in Sevastopol comes as Ukraine steps up drone attacks against other Black Sea Fleet locations. On July 6, drones struck the fleet's facilities in Novorossiysk, Krasnodar Krai, a key port east of Crimea across the Kerch Strait.
