Nikolai Kalashnik, Ukraine's Minister of Infrastructure, called on ICAO Secretary-General Juan Carlos Salazar Gomez to completely stop civilian flights over Russia. ^[1] Ukraine's Foreign Minister Andrii Sybiha said on 2026-09-02 that Ukraine filed an official warning with the International Civil Aviation Organization (ICAO) advising airlines to avoid Russian airspace due to increased military activity, citing the risk of unintended incidents and invoking Ukraine's right to self-defense. ^[2] The International Civil Aviation Organization (ICAO) warned on Wednesday that commercial aircraft face increasing threats globally due to armed conflicts. ^[3] The International Civil Aviation Organization (ICAO), a UN agency based in Montreal, issued a warning to all member states urging them to strengthen commitments to protect civil aircraft from risks in conflict zones, following Ukraine's official declaration that Russian airspace is unsafe. ^[4] Ukraine's infrastructure minister, Mykola Kalashnyk, wrote to Juan Carlos Salazar, chair of the International Civil Aviation Organization (ICAO), requesting a complete ban on civil flights over Russia. ^[5] Nikolai Kalashnik stated that the presence of civilian aircraft in Russian airspace may carry particularly high risks. ^[6] Ukraine requested that ICAO take measures to ensure the safety of civil aviation. ^[7] EU foreign policy chief Kaja Kallas said on 2026-09-02 that a number of EU member states had pledged to provide Ukraine with extra air defense, without naming the countries, and that countries holding interceptor missiles such as Patriots were urged by the Netherlands to hand them to Ukraine. ^[8] German media Süddeutsche Zeitung, NDR and WDR reported that German authorities suspect two men of Russian background in the drone incident at Leipzig/Halle airport: a Latvia-born man allegedly linked to Russian intelligence who arranged logistics and instructions, and a Belarusian man holding a Russian passport whose DNA was found on a drone and a nearby antenna. ^[9] Ukrainian President Volodymyr Zelensky previously issued a similar warning about Russian airspace, pointing to increasing Ukrainian drone attacks on Russia, and air traffic at Russian airports has repeatedly been halted by overflying Ukrainian drones and missiles. ^[10] ICAO requested that states evaluate the security of airspace under their control, share intelligence on threats, and improve coordination between civil and military authorities to prevent civilian aircraft from being mistaken for military targets. ^[11] Ukraine formally notified ICAO on Wednesday of increased military activity in Russian airspace, stating it will no longer be safe for commercial air traffic and urging flights to avoid it. ^[12]
