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.

Russian authorities reported damage and a fire at Ust-Luga port during an overnight drone attack on 1 September. One drone crossed Latvian and Estonian airspace, prompting NATO to scramble Turkish F-16s.

The attack hit a major outlet for Russian energy exports. Reuters reported that Ust-Luga loads about 700,000 barrels of crude a day and exported 32.9 million metric tons of oil products in 2025. Its terminals also serve shadow-fleet tankers used to bypass sanctions.

Leningrad Oblast Governor Alexander Drozdenko said emergency crews were working in Ust-Luga’s port zone while the damage was being assessed. He later claimed Russian air defenses downed 52 drones over Leningrad Oblast and reported no casualties.

Drozdenko did not identify the damaged facility or specify the scale of the fire.

Militarnyi published an image attributed to the Exilenova+ monitoring channel showing a blaze near the port. The image’s time and precise location have not been independently verified.

There was no immediate information on whether the attack disrupted port operations. Ukraine had not claimed responsibility at the time of publication.

The regional warnings coincided with a broader drone attack on western Russia that included Ust-Luga, although authorities did not specifically link the drones approaching or entering NATO airspace to the port strike.

Baltic states issue warnings as NATO fighters scramble, while Finland restricts traffic

Estonia warned residents in eight counties and scrambled Turkish fighter jets serving in NATO’s Baltic Air Defense Mission, which protects the skies of Estonia, Latvia, and Lithuania.

Estonian Air Force Commander Brigadier General Riivo Valge said around a dozen drones had moved near the country’s border. One briefly entered southeastern Estonia, while another approached Narva before turning back into Russia. The fighters did not open fire, and the warnings were lifted by about 5:30 a.m.

Latvia issued two warnings overnight, first in the Ludza municipality and then in the Alūksne municipality. Latvia’s Armed Forces said a drone crossed Latvian airspace and continued into Estonia, where NATO fighters searched for it. The Latvian alerts ended at around 4:20 a.m.

Finland’s Armed Forces introduced temporary air and sea restrictions over the eastern Gulf of Finland at 3:37 a.m.

The military lifted both restrictions shortly after 6 a.m., saying no drones had strayed into Finland.

Repeated strikes on Ust-Luga

Ust-Luga lies around 110 kilometers west of St. Petersburg and some 900 kilometers from Ukraine. It is the endpoint of the Baltic Pipeline System-II, which carries Russian crude to the port for export. The area hosts facilities operated by Russian gas producer NOVATEK and fertilizer maker EuroChem.

Ukraine began its series of 2026 attacks on Ust-Luga overnight on 24–25 March. The Security Service of Ukraine, the country’s counterintelligence agency, and the military’s elite Special Operations Forces confirmed that they had struck NOVATEK’s gas-condensate complex, which processes liquid hydrocarbons into fuels.

Further attacks followed in late March. They set fuel-storage tanks ablaze, damaged a pier and pumping equipment, and temporarily halted port operations, according to Russian Telegram channel Astra.

On 7 April, Ukraine’s General Staff, the military’s senior command, confirmed another strike on Ust-Luga’s oil terminal, saying three oil storage tanks were destroyed. Another attack on 14 August again caused damage and a fire, Drozdenko reported at the time.

A Russian drone hit a fire truck driving to a call in the village of Kushuhum outside Zaporizhzhia on 1 September, injuring four rescuers, the head of Zaporizhzhia Oblast, Ivan Fedorov, reported. The crew was on its way to a house fire that Russian shelling had started. The strike came hours after a countrywide Russian air assault overnight.

A drone hit the crew before they reached the fire

Fedorov said a Russian drone struck the State Emergency Service vehicle in Kushuhum as it drove to put out a fire. The truck took damage, and the crew was hurt. He said the men were under the supervision of medics.

The Main Directorate of the State Emergency Service in Zaporizhzhia Oblast confirmed the attack, and added that all four injured firefighters had been taken to hospital with injuries of differing severity. The directorate specified what the crew had been sent to: a fire in a detached house in the suburb, started by Russian shelling.

Over the past 24 hours, Russian attacks on Zaporizhzhia city and district killed two people and injured eight, Fedorov said. Russian forces carried out strikes on 57 settlements across the region.

The night before: a countrywide strike

Overnight into 1 September, Russia attacked with ballistic and cruise missiles, anti-radar missiles, Banderol munitions, and 218 Shahed-type strike drones, about a third of them jet-powered, Ukraine's Air Force reported. By preliminary data, air defenses downed or suppressed 199 targets. Odesa and Kyiv oblasts were the main directions of the strike.

Russia killed 12 people across Ukraine, among them a citizen of India, and injured dozens, Ukrainian President Volodymyr Zelenskyy said. Russia killed four people and injured 13 and damaged a five-story residential building, and 50 people were evacuated. Nearly 350 rescuers worked in Kyiv and the surrounding oblast alone.

In Kyiv, a ballistic strike on Ukrzaliznytsia railway facilities killed seven people, six of them railway workers, and one more employee remains hospitalized. The capital's overall toll for the night stood at eight killed.

In Odesa Oblast, Russian drones, guided bombs, and missiles injured seven civilian men, four of whom went to hospital, and struck the Orlivka ferry crossing on the border with Romania again, the regional prosecutor's office found. 

Ukraine has documented Russia striking the people who respond

As of May, Ukraine has documented 11,000 Russian first-person-view drone attacks on civilians, among them repeat strikes on the same spot once medics and firefighters arrive. Ukraine's UN envoy has built part of the case for expelling Russia from the Security Council on that practice.

Rescue workers in Zaporizhzhia have been caught that way before. After a strike on a Poltava Oblast gas site, Russia hit the crews who came to the fire. Firefighters in Chernihiv Oblast went to hospital mid-rescue. In Kryvyi Rih in August, a second Russian attack reached rescue workers thirty minutes after a drone strike on a shopping center, and a repeat strike killed a 20-year-old volunteer paramedic in Kyiv the same month.
