Russian forces struck Kyiv for a seventh consecutive night on 2–3 September, with drone attacks hitting a university, residential buildings, and a medical facility, injuring at least 13 people [9][25]. Ukraine's Air Force reported Russia launched 163 strike UAVs overnight, of which 135 were downed, with hits recorded at 15 locations across the country [22][18]. The overnight barrage killed at least five people and wounded at least 66 across Ukraine, with strikes reaching western Khmelnytskyi and Vinnytsia oblasts [18]. In Odesa, 17 people including three children were injured and more than 350,000 homes lost power [3][25].

Ukraine's long-range drone campaign simultaneously reached deeper into Russian territory. Moscow Mayor Sergei Sobyanin reported that 8,670 Ukrainian drones flew toward the Moscow region between 1 August and 1 September, with 795 destroyed on approach [10]. Overnight on 2–3 September, the Russian Defense Ministry reported intercepting 416 Ukrainian drones over 15 regions [7][17], with a separate daytime tally of 426 over 12 regions on 3 September [1]. Russian officials gave conflicting counts for the Moscow area, with Mayor Sergei Sobyanin reporting 64 drones downed [7] while other accounts reported 40 to 56 [17][29]. Moscow Oblast Governor Andrey Vorobyov confirmed drones hit residential buildings in Pavlovsky Posad and Kubinka and a factory in Bolshoye Bunkovo, with fires but no casualties reported [19][29]. Ukraine's Unmanned Systems Forces reported destroying five air-defense elements, including radar systems, at Russian airfields at Yeysk and Millerovo [30], and Ukraine's Navy said it struck the Russian support vessel Nefrit near Sochi [12].

President Volodymyr Zelenskyy framed the drone campaign as a deliberate strategy to make Russian airspace unsafe, warning airlines and insurers that "the safe days in Russia's skies are over" and that Ukrainian drones would be present for the duration of the war [3][5][11]. Ukraine formally notified ICAO that Russian airspace is unsafe and asked member states to prohibit civil aircraft operations there [5][20]. Zelenskyy said the first airlines had begun suspending flights to Russian airports following his warning [17]. Turkish carrier Pegasus cancelled 12 Turkey-Moscow flights [6], though it later attributed some cancellations to "technical and operational reasons" [11].

Putin called Zelenskyy's airspace warning "state terrorism" and said Russia would respond immediately if civilian aircraft were targeted [5][6]. Speaking at the Shanghai Cooperation Organization summit in Bishkek, Putin said Russia would not negotiate with those it considers terrorists [6][11][35]. Russian Transport Minister Andrei Nikitin said authorities "have responses to all these threats that the terrorists express" and pledged to prevent significant disruption to domestic air travel [10][17].

Aviation-risk analysts documented systematic disruption of Russian civil aviation. Osprey Flight Solutions stated Ukraine has been "systematically disrupting Russian airspace for months" and warned that deep strikes near Moscow and St. Petersburg could occur almost daily through the end of 2026 [5][11][20]. Aviation consultant Xavier Tytelman said the disruption of hundreds of daily internal Russian flights cannot be replaced by rail in such a vast country, creating a mobility and economic burden that is "the side effect that the Ukrainians are seeking to attain" [20]. Aeroflot General Director Sergei Aleksandrovsky confirmed that foreign airlines' share of Russia's international passenger traffic grew from 30 percent in 2024 to 47 percent in 2025 [11]. ICAO issued a generic warning that risks of civilian aircraft being targeted or caught in crossfire are growing, without attributing blame to either side [5][23]. Former British military intelligence officer Philip Ingram interpreted Zelenskyy's warning as aimed at airlines from the Middle East, Southeast Asia, and China still flying into Moscow, describing it as "part of the information war and bringing the overall conflict to the Russian people" [16].

On the ground, civilians on both sides described the toll. Kyiv resident Yulia said she is "fatalistic about them — that there's no sense of threat, or a desire to hide somewhere" [8]. Kindergarten teacher Valentyna Mykolaivna called the constant alarms "Це дуже виснажує, просто дурдом якийсь" (This is very exhausting, just some kind of madhouse) [31]. Ukrainian military experts Roman Svitan and Alexander Kovalenko said Russia's use of jet-powered KAB glide bombs — now launchable from over 100 kilometers away — is designed to overwhelm air defenses over dense civilian areas, with Svitan calling the mass use against Odesa "war crimes, open terrorism, and genocide" [26]. In Moscow, book editor Piotr said "the first cracks have appeared in the façade of Moscow's well-being" as a result of Ukrainian drone attacks, and motorcycle enthusiast Ievgeni described sleepless nights whenever he receives an alert [41].

The drone exchange unfolded alongside a European diplomatic crisis over the 4 August attempted drone attack at Leipzig/Halle airport. Germany formally attributed the incident to Russia, with Interior Minister Alexander Dobrindt saying those involved "acted on behalf of Russian state bodies" [21][4]. The EU branded it state-sponsored terrorism, with Kaja Kallas announcing the bloc's largest sanctions package against Russia's military-industrial complex and Belgian Foreign Minister Maxime Prévot saying Russia cannot "carry out this type of operation in our countries without consequences" [4]. NATO Secretary General Mark Rutte said NATO is preparing to protect its population [4]. Germany closed the Russian Consulate General in Bonn and the Russian House in Berlin [2][3]. Russia rejected the accusations, with the Russian Embassy in Berlin calling them "a hastily assembled provocation" and Putin accusing Germany of fabricating evidence [21][15]. Russia's chargé d'affaires in London, Vasily Tsyganov, rejected British allegations as a "coordinated provocation" [2].

German officials insisted the country is not formally at war. Dobrindt said "we are not at war, but we are the daily target of hybrid warfare" [15]. Chancellor Friedrich Merz vowed that perpetrators "will pay a price" [15]. Green Party lawmaker Sara Nanni criticized the government's response as "a bit late" and "not enough," and CDU security expert Roderich Kiesewetter called for delivery of Taurus cruise missiles to Ukraine and activation of NATO Article 4 [15]. The AfD party opposes further military support for Ukraine and seeks normalized relations with Russia [15]. Western security services described a broader wave of hybrid sabotage: Danish intelligence stated Russian services are "actively preparing sabotage actions against Denmark's defence industry" [12]; Slovak police foiled an arson attack against the Skyeton drone factory near Prešov [27]; Czech Security Information Service spokesman Ladislav Sticha said "Russia is trying to attack the whole of Europe through hybrid means" [27]. A group calling itself "Global Citizens against War 1984" claimed responsibility for the Slovak attack, framing it as an autonomous peace campaign [27].

China's Foreign Ministry spokesperson Guo Jiakun said "对话谈判是解决乌克兰危机的唯一可行出路" (Dialogue and negotiation are the only viable way out of the Ukraine crisis) and urged all parties to remain calm and restrained [32]. India's External Affairs Minister Subrahmanyam Jaishankar visited Kyiv and said India is "ready to help end the war in any way it can" [12]. Zelenskyy said Ukraine has received confirmation that US presidential emissaries will hold meetings in Moscow and Kyiv within days [12]. Putin, speaking in Vladivostok, ruled out a new mobilization and said a settlement is possible if the problem is solved by Russia and Ukraine themselves [12]. Military analyst Rob Lee said the conflict is "a question of how much suffering Russia and Ukraine can withstand," adding that Russia can endure very high levels of pain [41]. Zelenskyy called the world's response to Russia's strikes insufficient and urged partners to speed up delivery of air-defense systems and sanctions [8][18].
