Ukraine's president has issued a stark warning to international carriers, insurers and passengers that Russian airspace is rapidly becoming unsafe due to his country's expanding drone campaign. Volodymyr Zelensky delivered the alert during his evening address on Tuesday, September 1, 2026, directing it specifically at airlines continuing to operate flights to major Russian airports in cities including Moscow and St Petersburg.
"We want to warn every airline that uses Russian airspace, every insurer, everyone who still uses key Russian airports: the Russian sky is becoming completely dangerous,"Zelensky said. According to reporting from international news outlets, he further sharpened the language by stating that
"the safe days in Russia's skies are over."
In his address, Zelensky clarified that Ukraine's intention was not to endanger civilian aviation itself.
"Ukraine does not threaten civilian aviation as such - not a single civilian aircraft,"he said, emphasizing that his country did not seek the loss of innocent lives. Rather, he explained the practical reality facing airlines:
"There will simply be drones in Russia's skies on a scale that has to be taken into account."
How has Russia responded?
Russian President Vladimir Putin rejected Zelensky's warning, characterizing it as a serious escalation. Speaking at the Shanghai Co-operation Organisation summit in Kyrgyzstan, Putin described Zelensky's comments as amounting to a
"declaration of state terrorism."He added that Russia would continue its military operations against Ukraine, which have intensified significantly in recent weeks.
"They are asking us to resume negotiations... but you don't negotiate with terrorists,"Putin told reporters.
Putin acknowledged that Ukrainian strikes had damaged infrastructure inside Russia, though he claimed that
"only 10%"of oil refineries remained in need of repair. Russia's military has announced preparations to carry out
"massive"strikes on Ukrainian power stations in response.
What is the scale of Ukraine's drone campaign?
Ukraine has significantly expanded its drone operations deep inside Russian territory in recent months. The country has targeted energy facilities far from the front lines and conducted repeated attacks on depots belonging to Russia's two largest online retailers, Wildberries and Ozon. According to reporting on the escalation, Zelensky indicated that drones would remain in Russian skies
"for as long as the war persists."
These drone attacks have already caused substantial disruption at some of Russia's largest airports, particularly in Moscow where all four major airports have at times been forced to halt both arrivals and departures. Several cancellations were reported on Wednesday following Zelensky's warning. Ukraine does not necessarily need to strike airports directly to cause operational chaos; under Russia's air defence "Kovyor" (carpet) plan, flights are suspended whenever a drone is detected in the relevant airspace.
Aviation risk advisory firm Osprey Flight Solutions issued an alert to clients noting that while the majority of Ukraine's drone and missile strikes were likely to occur within 300 kilometres of the border, daily attacks deeper inside Russia were almost certain to continue throughout the year. The firm assessed that
"there is also a realistic possibility that the frequency of Ukrainian strikes will continue to increase in the short term deep inside Russian territory"and warned that
"miscalculation and/or misidentification is likely in areas related to the Ukraine conflict."
Which airlines currently use Russian airspace?
Most Western commercial airlines have avoided Russian airspace since Russia's full-scale invasion of Ukraine began in February 2022. However, carriers from countries including Turkey, China and Gulf states continue to operate flights through Russian airspace, taking advantage of time and fuel savings on routes between Asia and Europe. Ukraine itself has maintained a complete closure of its airspace to civilian aircraft throughout the conflict.
What is the historical context for aviation safety concerns?
The risks posed to civil aviation during the Ukraine conflict are not theoretical. In 2014, months after war erupted in eastern Ukraine between Russian-backed separatists and the Ukrainian military, a Russian-made missile brought down a passenger aircraft, killing all 298 people on board. Last year, the United Nations aviation agency concluded that Russia was responsible for the downing of Malaysia Airlines Flight MH17 over eastern Ukraine in July 2014, a finding the Kremlin has consistently denied.
More recently, in 2024, Putin apologized to the president of neighbouring Azerbaijan following the downing of a commercial airliner in Russian airspace that killed 38 people. He attributed the
"tragic incident"to Russian air defence systems that were
"repelling Ukrainian drones."
How has the conflict intensified in recent days?
Russia's military operations against Ukraine have escalated sharply. Heavy strikes on Tuesday killed 12 people, with further attacks reported on Odesa, Sumy and Kyiv on Wednesday. The Ukrainian capital and its surrounding region have come under attack for seven consecutive days. Zelensky has repeatedly emphasized that Ukraine is now bringing the conflict back onto Russian territory; a few weeks prior to this warning, he stated that Ukraine's military had
"begun the process of bringing the war back to Russia,"and at the weekend he reiterated that Russia must feel the war was
"returning to where it came from."
This latest warning to airlines represents a deliberate escalation of Zelensky's messaging. Earlier in the conflict, following overnight drone strikes on Moscow, Zelensky warned that if Ukraine suffers, Moscow will too, while also urging increased sanctions on Russia. More recently, Zelensky has been pressing NATO for urgent air defence systems amid the intensified Russian missile strikes, highlighting the need for more interceptor missiles to protect Ukrainian civilians.
