Russian President Vladimir Putin said Moscow would “find a way to respond” if civilian “tragedies” followed President Volodymyr Zelenskyy’s warning that Ukrainian drone operations were making Russian skies unsafe. Zelenskyy told foreign airlines and insurers that the “safe moments” in Russian airspace were over.

Zelenskyy’s warning seeks to extend the cost of Russia’s war beyond damaged military and energy facilities to airlines, insurers, and travelers. It does not mean Russian airspace is legally or completely closed. However, carriers that continue flying over Russia face higher costs from repeated airport shutdowns during drone alerts, as well as the danger that military activity in Russian airspace could endanger civilian aircraft.

Putin spoke after a 1 September Shanghai Cooperation Organization summit in Bishkek, where Russia and China coordinate regional security. Zelenskyy’s warning amounted to “a bid for state terrorism” if he had made it publicly, the Russian president said, adding that Russia does not negotiate with “terrorists.” Putin also said Russian forces were preparing massive strikes on Ukraine’s energy infrastructure.

In his evening video address, Zelenskyy said Ukraine did not threaten civilian aircraft but would keep striking Russian military targets and parts of the economy supporting the war. Ukraine’s Presidential Office head Kyrylo Budanov backed the decision, saying long-range weapons would systematically strike military targets in Russia while the invasion continued.

“Russian airspace will effectively be closing”: Zelenskyy warns airlines Russian skies are no longer safe

Shares in Aeroflot, Russia’s national airline, fell to an intraday low of 30.36 rubles at about 20:40 Moscow time, down 5.11%, Meduza reported, citing Moscow Exchange data. The timing does not establish that Zelenskyy’s speech alone drove the decline.

Wall Street Journal correspondent Yaroslav Trofimov posted a chart of the decline on X, writing, “Aeroflot shares after Zelensky’s warning.”

European and US carriers already avoid Russian airspace, but airlines from China, Türkiye, the United Arab Emirates, and other Gulf states continue using it, Reuters reported. Aviation-risk firm Osprey Flight Solutions assessed that daily attacks deep inside Russia were nearly certain through 2026 and warned of possible misidentification.

Andrii Kovalenko, head of Ukraine’s Center for Countering Disinformation, said it was “strange” to hear terrorism accusations from “the leader of a terrorist organization masquerading as the Russian state.” Putin’s reaction showed Moscow feared pressure on its airspace, he argued.

Previous closures of Russian airspace due to Ukrainian attacks

Russian airports were repeatedly shut during Ukrainian drone alerts well before Zelenskyy’s warning. On 6 July 2025, Moscow airports canceled 171 flights while airports in five other cities suspended operations.

A 27 May attack closed airports serving Moscow and several other cities after Russia claimed it intercepted 99 drones. Another wave caused flight disruption and mobile internet outages around Moscow, while a 29 May alert again halted flights at Moscow airports.

More recently, Russian authorities restricted operations at Moscow airports during Ukrainian drone attacks, delaying more than 450 flights

Ukrainian President Volodymyr Zelenskyy warned airlines, insurers, and other aviation stakeholders on 1 September that Russian airspace is becoming increasingly dangerous as Ukrainian drones operate deeper inside the country.

The warning comes as Ukraine has increasingly carried out long-range drone strikes deep inside Russia, targeting military, energy, industrial, and other infrastructure. Russian authorities have repeatedly reported temporary airport closures and flight disruptions during drone attacks as part of air defense measures.

“We want to warn every airline that uses Russian airspace, every insurer, and everyone who still uses Russia’s key airports: Russian airspace is becoming completely unsafe,” Zelenskyy said.

“Russian airspace will effectively be closing”

Zelenskyy said Ukraine does not intend to threaten civilian aviation or civilian aircraft, but warned that the growing presence of drones over Russia means airlines must account for the risks.

“We in Ukraine do not want innocent lives to be lost. That is why we are warning our partners: the safe days in Russia’s skies are over,” he said.

Zelenskyy accused Russian authorities of failing to properly inform airlines about the risks, saying they have not adequately communicated the growing danger posed by drones in Russian airspace.

“Although the Russian authorities are not properly informing people about this, Russian airspace will effectively be closing,” Zelenskyy said, arguing that Russia’s war against Ukraine is making its own airspace unsafe.

Zelenskyy warned that the growing scale of Ukrainian drone operations over Russia will have to be factored into aviation risks. “There will simply be drones in Russia’s skies on a scale that has to be taken into account,” he said.

He called on foreign ambassadors in Ukraine and Russia to relay the warning to their governments, and said Ukraine’s Foreign Ministry and other institutions would provide international organizations with information about the risks to Russian airspace.

“Drone-infested skies are no place for civilian aviation,” Zelenskyy said.

Ukraine closed its skies in 2022. Russia has kept flying

The warning highlights a stark difference between the two countries. Ukraine has kept its airspace closed to civilian aviation since Russia launched its full-scale invasion in February 2022. 

The risk is familiar to Ukraine. Russian forces have repeatedly attacked Ukrainian airports and aviation infrastructure during the full-scale invasion, making the continued operation of civilian aviation impossible.

Russia is also responsible for the 2014 downing of Malaysia Airlines Flight MH17 over occupied eastern Ukraine, which killed all 298 people aboard, showing the danger Russia’s military activities can pose to civilian aviation. 

Russia, meanwhile, has continued operating major airports and regular passenger flights despite Ukrainian drones increasingly reaching deep into its territory. EASA has warned that Russian air defenses responding to Ukrainian drone and missile attacks could pose risks to civilian aircraft, including through misidentification, particularly around major airports.

Russian airports increasingly disrupted by Ukrainian drones

Russian authorities have repeatedly restricted or suspended flights at Moscow and other airports during Ukrainian drone attacks. The disruptions have generally come as Russia activates air defenses against drones targeting military, energy, industrial, and logistics infrastructure.

Russia has also moved toward broader restrictions on civilian aviation. In June, Russia imposed new restrictions on light aircraft around Moscow and neighboring regions, while regular passenger and charter flights remained exempt.

The result is a growing disruption to Russian aviation even as Moscow continues to keep its main passenger airspace open: Ukrainian drones are not being used to target civilian aircraft, but their increasing presence is making normal aviation operations more difficult and forcing Russia to restrict or suspend flights during attacks.

Ukraine's weapons marketplace DOT-Chain Defense has compressed delivery times from months to weeks after one year of operation, the country's Defense Ministry reported. For the fastest product categories—electronic warfare gear, ground robots, interceptor drones—orders now reach units within 24 hours.

Ukraine's war against Russia's invasion has pushed Kyiv to rebuild military procurement from the ground up, trading slow bureaucratic pipelines for digital platforms where frontline units pick and receive their own weapons faster than Western militaries have managed. Domestic manufacturers now make 90% of newly authorized systems.

Fastest deliveries measured in hours

The Defense Ministry and the Defense Procurement Agency DOT have jointly driven the acceleration, according to the ministry's statement.

"Delivery times for drones and other systems have shrunk from months to a matter of weeks, and often to days," the ministry said.

Beyond that general compression, several categories saw delivery within a single day. Electronic warfare systems, ground robotic platforms, reconnaissance and bomber drones, interceptor drones, and FPV drones on both fiber-optic and radio control all reached units within 24 hours. Ammunition for unmanned systems arrived within six days.

Russian drone attacks on Ukraine’s Danube ports hit recent high, Romania says

Over the first year, the platform shipped more than 1.2 million drones and other systems. Units now choose from 1,181 products made by 300 domestic manufacturers.

How the marketplace works

DOT-Chain Defense supplements centralized state supply rather than replacing it, the ministry noted. Combat units use allocated funds to browse and order the equipment they need for their section of the front. The marketplace handles contracts, payments, and delivery.

The platform's drone constructor tool lets units customize drone configurations before ordering. A dedicated training course on using the marketplace recently launched inside the Army+ mobile app.

Broader procurement picture

The one-year milestone caps a period of rapid scaling across Ukraine's defense procurement. The country contracted about $8 billion worth of drones in the first half of 2026—double the same period last year, according to the Defense Ministry.

More than 400 combat units now shop for weapons through the marketplace's companion Brave1 Market program using points earned for confirmed battlefield activity. Washington modeled its own Unmanned Aircraft Systems Marketplace on the Ukrainian original earlier this year.

The 1st Corps of Ukraine's National Guard, known as Azov, says it destroyed 67 Russian fuel tanks holding 4,221 tons of fuel in occupied Donetsk Oblast, in an operation it named Hell-2. The unit released video of the strikes on 17 August, saying it had spent a month tracking where Russian forces moved and stored the fuel before hitting it.

Fuel is the blood of Russia's war, which is why its forces increasingly hide storage sites and route deliveries through improvised logistics hubs. Strikes on those hubs strip Russian units of what they need to move, supply, and fight. There have already been cases of Russian forces concealing fuel in grain trucks in occupied territories.

Azov warned the Russian forces before the strike

Azov says it flagged the fuel sites a month before hitting them, and struck when the Russians kept using them anyway.

“A month ago, we warned the occupier: ‘Azov sees your movements and will strike at the right moment.’ But some units of the Russian Armed Forces continued to store fuel in occupied Donetsk Oblast,” Azov said.

Azov emphasizes that it does not attack civilian gas stations or civilians. The operation targeted facilities used to supply Russian occupation forces. At the same time, according to Azov fighters, Russian military infrastructure remains a legitimate target.

The Russians didn’t get the message the first time

Hell-2 is likely a follow-up to the Hell operation, during which the first series of strikes, Azov also targeted the fuel logistics of Russian forces in occupied Donetsk Oblast.

On 12 July, Azov reported striking a secret Russian fuel base in Novoamvrosiivka. Drone operators from the 1st Azov Corps of the National Guard conducted reconnaissance and used Hornet drones to strike the facility. The strikes damaged fuel tanks and the base’s infrastructure and blocked the railway track.

According to the report, the Russians used the facility as a logistics hub to supply their occupation forces. After the strike, they were forced to abandon the base and move their logistics operations from the occupied territory into Russia.

Ukrainian drones struck Moscow and the surrounding oblast overnight into 18 August, cutting power, setting off fires, and hitting a warehouse of the Russian online retailer Wildberries, monitoring Telegram channels reported. Russian officials claimed air defenses shot down most of the drones and blamed the damage on falling wreckage. Ukraine's military did not claim the attack.

Fires and casualties across Moscow Oblast

Ukrainian monitoring Telegram channel Exilenova+ began posting footage of the strikes around 4:00. Fires broke out on an apartment-block roof and in another building in a town east of Moscow, and a retail pavilion caught fire near a shopping mall in a town to the southeast, Russian news Telegram channel Astra reported. Moscow Oblast Governor Andrei Vorobyov claimed air defenses downed more than 150 drones over the oblast. He stated three people were hurt, and that debris damaged homes.

The attack knocked out electricity for more than 5,000 customers and 46 "socially significant" facilities in two districts east of the capital, knocking 109 transformer substations offline, the regional utility Mosoblenergo said. It blamed equipment damage early on 18 August and estimated about two hours to restore power.

A Wildberries warehouse hit

A drone hit a Wildberries logistics warehouse in the region, where Vorobyov said a fire was quickly contained with no casualties. Wildberries said debris only grazed a wall, that staff had been evacuated in advance, and that its goods were unharmed. Footage shared by Exilenova+ showed a large hole near the roof and no visible fire.

Russia's claims

Russian officials gave sweeping counts. Moscow Mayor Sergei Sobyanin claimed 620 drones flew toward the capital region overnight, with 180 downed there. Russia's Defense Ministry claimed it destroyed 791 drones over 15 Russian regions and occupied Crimea. In a separate daily tally, it claimed 1,671 drones over 24 hours, Interfax-Russia reported. Russian state news agency RIA Novosti called the claimed drone figure an absolute record. 

Ukraine's response

Ukraine's General Staff listed strikes on an ammunition depot in Donetsk Oblast and several drone-control points in Russia's Belgorod Oblast and Ukraine's Zaporizhzhia Oblast, but made no mention of the Moscow attack. 

Ukrainian defense-technology company Fire Point posted video of drones over the region, citing reported explosions near a Moscow oil refinery and a possible hit on warehouse infrastructure. Fire Point manufactures the FP-1—one of the types of long-range drones widely used in such attacks.

A campaign on a Russian retail giant

Wildberries warehouses have become a frequent Ukrainian target. On 16 August, Ukraine struck the retailer's logistics sites near Moscow, halting operations, and Kyiv has now knocked out seven of its 10 largest warehouses. The strikes have cost the company at least 17% of its warehouse space and pushed it to seek storage in Kazakhstan.

Estonia will use part of a new European Union loan to arm Ukraine with drones, drawing on a loan worth up to €2.34 billion, according to ERR. The loan will also rebuild its own air defense and ammunition stocks, and all of it must be spent by 2030.

As Moscow continues its all-out war in Ukraine, the EU's northeast is rearming fast, bracing for a Russia that regional military chiefs expect to be combat-ready again within two years.

What the loan buys

Estonia signed the financing deal with the European Commission under SAFE (Security Action for Europe), a €150 billion EU program that raises money jointly on the markets and lends it to member states on cheap terms to fast-track defense spending, its finance ministry said.

A share of Estonia's up-to-€2.34 billion will go to Ukraine as drones. The rest strengthens air defense, buys military vehicles, and refills artillery shells and other ammunition. The credit runs 45 years, and every purchase and delivery must be finished by 2030. Estonia filed its final application in November 2025.

Why the loan helps

Borrowing through SAFE lets Estonia raise money on better terms than it could alone, because the EU issues debt at lower rates. The bloc raises the money jointly and splits it among members. Estonia will hold defense spending above 5% of GDP, and the loan eases the strain that puts on its budget.

“Ukraine is becoming a security provider for Europe”: Ukraine signs Drone Deals with Estonia, the Netherlands, and Denmark as Europe taps Kyiv’s battlefield-tested weapons technology

Estonia, a NATO and EU state of about 1.3 million people, shares a 294-kilometer border with Russia and treats Moscow's war on Ukraine as a direct threat to its own security. It has studied that war closely for years and is now racing to rebuild its air defenses and ammunition stocks.

Kadri Peters, a deputy secretary general at Estonia's Defense Ministry, said the fast-changing security situation in Europe demands stronger, quicker defense from the whole alliance. She said large-scale purchases ahead will directly affect Estonia's security and the wider region.

US soldiers left for a “summer rotation.” Estonia doesn’t know how many are coming back—or when

In July, Estonia and the United States agreed to resume weapons deliveries in the coming months, after a pause tied to the war in Iran, with long-range ATACMS ballistic missiles the exception. In May, Washington had warned European allies of long delays as it drained its own stocks, mainly of HIMARS rocket ammunition and NASAMS air-defense missiles. The same shortages hit Ukraine the hardest: it currently struggles to shoot down Russian ballistic missiles for lack of US-made PAC-3 interceptors.

Estonia has been backing Kyiv since the beginning of Russia's full-scale invasion in 2022. It co-leads an IT coalition that has funneled over €1.4 billion into Ukraine's drone programs, and has moved to tap Kyiv's battlefield-tested drone technology for its own forces.
