Lithuania's president and prime minister were forced to take shelter on Tuesday, when a drone alert caused the capital Vilnius to come to a standstill.
President Gitanas Nauseda and Prime Minister Inga Ruginiene were taken to emergency shelters following the air alert, which ordered the city's population to take cover.
Flights were suspended and road and rail travel briefly ground to a halt. The alert has since been lifted. It is not yet clear who was behind the incursion.
It came a day after Estonia said NATO shot down a drone over its territory, which it suspected was a Ukrainian projectile knocked off course by Russian electronic interference.
An alert from Lithuania's defence ministry on Wednesday stated: Immediately take shelter in a safe place, take care of your close ones, await new recommendations.
Lithuania's national crisis management centre had issued an alert in response to a drone in neighbouring Belarus that was seen flying towards Lithuania. The drone's origin had not been confirmed, and further reports indicated that NATO jets were deployed to shoot down the drone but could not locate it.
This recent event is part of a troubling trend of drone incursions over NATO members, reflecting intensifying tensions in the region amidst ongoing conflicts and security concerns.
