• Ukrainian President Zelensky warns airlines that Russian airspace has become unsafe.
• The warning follows intensified drone operations by Ukraine targeting Russian infrastructure.
• Putin accuses Zelensky of "state terrorism" in response to the warning.
• Aviation risk advisory suggests increased Ukrainian drone strikes inside Russia.
• Most Western airlines have stopped flying over Russia due to safety concerns.

Ukrainian President Volodymyr Zelensky has issued a stark warning to airlines and insurers about the dangers posed by Ukrainian drones in Russian airspace, stating that it has become "completely dangerous." In his recent address, Zelensky emphasized, "Today, 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," reinforcing that Ukraine does not pose a threat to civilian aviation but stressing that "there will simply be drones in Russia's skies" moving forward, according to Reuters and SCMP.

This warning highlights an escalation in drone operations by Ukraine, which has seen increased effectiveness in striking Russian targets. Zelensky noted that the "war started by Russia is closing its skies" for civilian traffic, a statement underpinned by deteriorating airport operations in Russia due to approaching Ukrainian drones. He stated, "Drone-infested skies are no place for civilian aviation," noting the ongoing risk for airlines operating in major cities such as St. Petersburg and Moscow, as reported by BBC and Reuters.

In response, Russian President Vladimir Putin labeled Zelensky's comments as a declaration of "state terrorism," indicating a hardening stance amid stalled diplomatic efforts. According to Putin, "They are asking us to resume negotiations ... but you don’t negotiate with terrorists," highlighting the frayed relations between the two nations. Both leaders acknowledged that the ongoing conflict has led to civilian casualties; Zelensky reported that Russian missile attacks had killed at least 12 people in recent assaults, as stated by SCMP and BBC.

According to aviation risk advisory firm Osprey Flight Solutions, while many strikes are expected to occur within 300 kilometers of the border, attacks deeper into Russian territory will likely continue through the year. The advisory suggests that "there is a realistic possibility that the frequency of Ukrainian strikes will continue to increase in the short term," noted to be grounded in potential miscalculations in the heat of conflict, which has prompted Western airlines to largely avoid Russian airspace since the beginning of the conflict, aligned with the sentiments expressed by Zelensky, as reported by Reuters and BBC.
