Residents of Vilnius have taken shelter and Lithuania's president and prime minister were taken to safe locations because of an alarm over drone activity near the border with Belarus, underlining jitters on NATO's eastern flank over incursions related to Russia's war with Ukraine.
An emergency announcement from the military told people in the Vilnius region to "immediately head to a shelter or a safe place".
The alert, which lasted for about an hour on Wednesday, also led to the closure of the airspace over Vilnius Airport.
