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.
