Lithuanian military police secured a site near Pratkūnai on Tuesday after debris from an overnight drone strike was discovered.
Footage shows officers cordoning off the area and examining scattered fragments of the drone near the Kaunas Reservoir, roughly 100 kilometres west of Vilnius.
Authorities have launched an investigation into the incident, and the drone’s origin and purpose remain unknown.
Unidentified drones have repeatedly appeared over Lithuanian skies, which border Belarus—a key Moscow ally—and the Russian enclave of Kaliningrad.
