Unknown object crosses Lithuanian airspace; NATO jets scrambled as Russian strikes hit western Ukraine
An unidentified aerial object, most likely a drone, flew about 60–70 km through Lithuanian airspace early on 13 September before heading toward Russia's Kaliningrad Oblast. NATO fighter jets were scrambled, Vilnius Airport suspended operations, and a yellow-level air-raid alert was issued in parts of Lithuania. The incident coincided with Russian drone strikes on western Ukraine near the Polish border, including a passenger-train locomotive and a truck near the Yahodyn crossing.
Key points
- Lithuanian Armed Forces radars near Varėna recorded the object at 04:05 on 13 September; it crossed roughly 60–70 km of Lithuanian airspace before moving toward Kaliningrad.
- NKVC head Vilmantas Vitkauskas said the object was most likely a drone, likely originating from Belarus, though no object has been recovered.
- Vilnius Airport suspended operations; NATO fighter jets were scrambled, and a yellow-level air-raid alert was issued for Vilnius, Vilnius district, Trakai district and Elektrėnai district, lifted after roughly 38 minutes.
- After the scramble it was determined that radar signals had been caused by a flock of birds — contradicting the earlier assessment of a likely drone violation.
- The same night, Russian drones struck western Ukraine: a passenger-train locomotive was hit about 2 km from the Polish border and a gas station near the Yahodyn-Dorohusk crossing caught fire; Ukrzaliznytsia reported this was the second consecutive day of attacks on the railway.
- Damage was also reported in Stryi (Lviv Oblast), Ternopil, and Ivano-Frankivsk, where a multi-storey building and an industrial facility were hit and one person was injured.
Why it matters
An unidentified aerial object entered the airspace of a NATO and EU member state, prompting a scramble of alliance jets and a temporary shutdown of Vilnius Airport. The fact that Lithuanian authorities initially assessed the object as a likely drone — only to later attribute the radar signals to a flock of birds — illustrates the difficulty of distinguishing routine radar contacts from genuine incursions in the Baltic region. Because the incident coincided with Russian strikes on infrastructure near the Polish border, it also raises questions about the risk of spillover from the war in Ukraine into neighbouring NATO countries.
What happened
Early on 13 September, Lithuanian Armed Forces radars near Varėna detected an unidentified aerial object at 04:05. The head of Lithuania's National Crisis Management Centre, Vilmantas Vitkauskas, said the object flew roughly 60–70 km through Lithuanian airspace over about 20 minutes before moving toward Russia's Kaliningrad Oblast, and was most likely a drone originating from Belarus. Residents reported hearing the object overhead. Later in the day, at 12:56, Lithuanian authorities received new data about a possible unidentified object in their airspace, and at 12:59 a yellow-level air-raid alert was declared for Vilnius, Vilnius district, Trakai district and Elektrėnai district; Vilnius Airport suspended operations and NATO fighter jets — Italian Air Force Eurofighter Typhoons on the Baltic air-policing mission based at Šiauliai — were scrambled. The alert was lifted roughly 38 minutes later, around 13:37–13:45, after officials determined the radar signals had been caused by a flock of birds.
The same night, Russian drones struck western Ukraine. Ukrzaliznytsia said a passenger-train locomotive was hit about 2 km from the Polish border; no passengers or crew were injured, but the railway said this was the second consecutive day of Russian attacks on the line. Near the Yahodyn-Dorohusk crossing, falling debris damaged a gas station and set several trucks on fire, and operations at the border crossing were halted while people took shelter. Damage was also reported in Stryi (Lviv Oblast), Ternopil, and Ivano-Frankivsk, where a multi-storey building and an industrial facility were hit and one person was injured.
How Ukrainian sources describe it
The supplied Ukrainian-language source treats the Lithuanian airspace incident and the Russian strikes near the Polish border as a single overnight story rather than two separate national events, framing them as part of the same pattern of Russian aerial activity on 13 September.
Where reporting differs
Polish and Ukrainian officials gave differing accounts of what happened near the Yahodyn-Dorohusk crossing: Poland's Nadbużański border guard said a drone struck a truck near the crossing, while Ukraine's State Border Guard Service said there were no direct hits on the Yahodyn checkpoint. Within Poland itself, Defence Minister Władysław Kosiniak-Kamysz said Polish airspace had not been violated, even as the Polish Operational Command described the threat as 'real.' Lithuanian authorities also shifted their account: the National Crisis Management Centre and Vitkauskas initially described a likely drone violation, but a later official statement said the radar signals had been caused by a flock of birds.
Background
Lithuania is a NATO and EU member bordering Belarus and Russia's Kaliningrad exclave, both of which have been cited in earlier aerial incidents in the region. Poland borders western Ukraine and is a key logistics corridor for aid and refugee movement; the Yahodyn-Dorohusk crossing is one of the main road crossings between the two countries. In spring 2026, Ukraine said drones reach the Baltic states because of Russian electronic-warfare systems, and the foreign ministers of Lithuania and Estonia accused Russia of deliberately redirecting Ukrainian drones.
