Ukraine struck one of Russia's largest oil refineries deep in the Urals and a military airfield overnight in a long-range attack, Ukrainian President Volodymyr Zelenskyy announced on 21 August. The Ukrainian Army's General Staff confirmed the refinery and airfield hits, while Zelenskyy said the same night also reached the Black Sea and brought fresh damage from earlier strikes on a Russian warplane and a drone-launch site.

Fire at a major Lukoil refinery in Perm

Zelenskyy said the overnight drones hit the Lukoil-Permnefteorgsintez refinery — known as PNOS — in Perm, where the General Staff recorded a fire on the plant's grounds. The target sits more than 1,500 km from Ukraine's northern border, in a region near the Ural Mountains.

The refinery is one of Russia's largest, able to process more than 13 million tons of crude a year, with more than half its output sold abroad until recently. It supplies fuel to both Russia's economy and its army.

Ukrainian Telegram channels Supernova+ and Exilenova+ shared footage of explosions and a rising plume, with locals reporting a series of blasts at the site. Russia's Perm Krai authorities claimed they repelled the attack and downed 16 drones.

Kyiv has repeatedly hit the plant through the year. After a strike at the end of July, it had been running well below capacity.

Airfield, Black Sea, and other targets the same night

The General Staff said the same night's drones also struck the Marinovka military airfield in Volgograd Oblast, located in Russia's Volga region, with the damage still being assessed, while Zelenskyy added that Ukraine achieved unspecified results in the Black Sea. The military also reported hitting a drone storage and launch site near Donetsk, a materiel warehouse in occupied Crimea, two command posts in Donetsk and Zaporizhzhia oblasts, and six relay stations in Crimea used to steer Russia's Geran and Gerbera attack drones.

Zelenskyy also confirmed damage from earlier strikes: a Russian Su-34 fighter-bomber hit at the Akhtubinsk airfield, about 600 km from the front line, and a drone store and launch site struck at Primorsko-Akhtarsk, roughly 180 km away. The strike extends a run of deep hits this month, from the TANECO refinery in Tatarstan and a Black Sea oil terminal to three refineries hit in one night and an Omsk refinery struck 2,500 km away in Siberia.

President Volodymyr Zelenskyy allowed preparations for an AI-guided drone campaign against Moscow-area airports, The Atlantic reported on 20 August, citing two anonymous sources with direct knowledge of the proposal.

The reported plan sought to keep civilian flights grounded long enough to pressure Russia’s elite. Had it proceeded, it would have moved Ukraine toward large-scale autonomous strikes, raising questions under the laws of war about attacks without human confirmation. The Atlantic's disclosure follows months of reported Ukrainian attacks that repeatedly forced Moscow-area airport closures and sent increasingly large drone swarms toward the capital.

How the drone operation would have worked

Code-named M&Ms, the operation called for as many as 1,000 drones to fly toward Moscow-area airports each night and overwhelm Russian air defenses, one source said.

Onboard cameras would compare live views with preloaded maps and target images. They would also allow the drones to strike without pilot confirmation and to navigate without a remote-control link that is vulnerable to Russian electronic jamming, the sources said.

One source said prolonged airport closures were intended to pressure Kremlin-linked elites and push Vladimir Putin toward negotiations.

The plan was presented to Zelenskyy during the winter of 2025–26, The Atlantic reported. Preparations stopped after Zelenskyy dismissed Defense Minister Mykhailo Fedorov, whom The Atlantic described as the operation’s mastermind, in July, both sources said. One source said another team could revive the project within about three months.

Both sources said Zelenskyy allowed preparations despite concerns that a drone could hit a civilian airliner. Planners proposed warning airlines, according to one source.

A Zelenskyy spokesperson declined to comment. Another unnamed presidential office official called the report “total nonsense,” saying Ukraine lacked long-range weapons reliable enough to strike the airports without posing undue risks to civilians.

Previous Ukrainian strikes on Moscow

The alleged M&Ms operation never launched, but other reported Ukrainian drone attacks repeatedly disrupted Moscow’s airports.

From 5 to 7 May 2026, restrictions imposed amid reported Ukrainian drone attacks delayed more than 450 flights at Moscow airports. Limits at Vnukovo remained in place for nearly 18 hours, EP reported, citing the independent Russian investigative outlet Agentstvo.

Earlier this week, Russian authorities claimed that 620 drones flew toward Moscow in one night, EP reported. The Atlantic placed Russia’s nationwide interception claim for that night at 791 drones. Ukraine’s military did not claim the attack.
