On September 13, Vilnius airport in Lithuania was closed and a NATO fighter jet was summoned from Siauliai, where the Italian air force is based as part of the NATO Baltic Air Defence mission, due to a reported drone sighting. The situation lasted about an hour before it was confirmed that the initial radar marks were actually caused by birds, not drones. The airport reopened within 38 minutes after visual identification from the jet. This incident highlights growing concerns over military drones straying into airspace near NATO's borders with Russia amid the ongoing conflict in Ukraine.
