Lithuania sounds air alert, closes Vilnius airspace over object it could not identify

Lithuania placed Vilnius County under an air alert on Saturday morning and temporarily shut the controlled airspace around Vilnius Airport after an object deemed potentially dangerous entered the country's airspace, prompting NATO fighter jets to scramble. Authorities lifted the alert after about 50 minutes, saying the object, which they had not fully identified, had posed no danger.

The National Crisis Management Center issued the warning for Vilnius County and for the area around the city of Ukmerge, Russian state news agency TASS reported, citing the center's statement as relayed by Lithuanian public broadcaster LRT. Vilnius County is made up of eight municipalities, LRT said. According to TASS, the jets sent up were NATO aircraft based at Zokniai Air Base.

Reuters said NATO Baltic Air Policing jets were sent up after a suspected drone was reported heading into Lithuania from Belarus, and that Vilnius airport was shut for less than an hour. Authorities were working on Saturday to establish what had set off the alert, the agency said.

Birds or a drone

Vilmantas Vitkauskas, director of the National Crisis Management Center, told LRT Radio while the alert was in force that the object had not yet been fully identified and that fighter jets had been scrambled. Residents reported seeing a possible object outside the Vilnius area heading toward Jonava, Vitkauskas said, but officials could not confirm those reports. He said the object's relatively slow speed meant a flock of birds could not be ruled out, although the center said there were indications it could be a drone.

The alert began at the yellow level and ended with a white all-clear telling residents they could leave shelters and safe places. "It was confirmed that there was no air threat, as the object posed no danger," Vitkauskas said. The object remained unidentified when LRT published its report. None of the officials quoted by LRT, TASS or Reuters attributed it to any state or linked it to the hybrid campaign that Danish intelligence has warned Russia will widen in Europe.

What it means

The episode captures the dilemma facing NATO's front-line members: an object slow enough to be mistaken for birds can still trigger a county-wide alert, close a capital's airspace and send allied fighters aloft. Vilnius chose caution and then stood down within an hour once the object was judged harmless, an approach that limits risk but carries a cost in disruption every time it is used. The open questions, namely what the object was and where it came from, matter more than the brief closure itself. If Lithuania cannot answer them, the incident will add to pressure on the alliance's eastern flank to improve how quickly it identifies slow, hard-to-classify objects, not only how fast it can intercept them.
