Zelenskiy warns airlines of Ukrainian drones in Russian airspace

Ukrainian President Volodymyr Zelenskiy issued a direct warning to airlines and insurance companies on Tuesday, saying that the presence of Ukrainian drones has made Russian airspace dangerous to use and that it is effectively closing. Speaking in his nightly video address, Zelenskiy said, "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."

Zelenskiy stressed that Ukraine poses no threat to civil aviation, "but there will be drones in Russia's skies and due notice must be taken." He added, "Although Russian authorities are not properly announcing it, Russian airspace will effectively be closing. The war started by Russia is closing its own skies."

The warning underscores a distinction between Ukraine's drone operations and any direct threat to civilian aircraft. The statement is directed at commercial aviation stakeholders, urging them to factor the presence of Ukrainian drones into their risk assessments for Russian airspace.

The warning comes amid a recent escalation in Russian air attacks on Kyiv and other cities. Moscow's latest strike killed 12 people and injured many more, marking the sixth straight day of intense assaults on the Ukrainian capital. Ukraine has responded with frequent drone strikes on Russian targets, many associated with the country's oil industry as well as retail sites.

Open letter to Putin

In a parallel development, Zelenskiy published an open letter addressed directly to Russian President Vladimir Putin, calling for an end to the war. The letter proposed a bilateral meeting between the two leaders and outlined Ukraine's position on potential negotiations.

The Kremlin has confirmed that it has seen the open letter, stating that Putin will be briefed on its contents later. This acknowledgment marks the first formal recognition by Moscow of the letter, though no substantive response or policy position has been issued by the Russian side as yet.

Zelenskiy on Donetsk

Separately, Zelenskiy asserted that Russia will not be able to occupy the Donetsk region this year, issuing a firm warning that Ukraine will continue fighting should Moscow refuse to end the war. Zelenskiy's remarks on Donetsk signal Ukraine's resolve to defend the contested eastern region against Russian advances. By declaring that occupation of the area remains out of reach for Russia within the current year, Zelenskiy sought to project confidence in Ukraine's defensive capabilities. His statement underscored that any continuation of hostilities would be a direct consequence of Moscow's choices, framing Putin as the key decision-maker in determining whether the conflict persists.

What was claimed, and who backed it

AI-extracted; can misattribute a claim — see Methodology.

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status is Contested when two claims on this page negate each other; otherwise it counts the distinct outlets we found asserting that specific claim — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
