Greek authorities are investigating the discovery of a Ukrainian-made naval drone found in a cave on an island in the Ionian Sea, according to multiple reports.

Greek media reported that the drone was found with explosives, though official details about the device's specifications and potential capabilities have not been confirmed by authorities. The discovery has prompted an investigation by Greek officials.

The finding comes amid ongoing conflict between Russia and Ukraine, with both nations employing various types of unmanned systems in naval and aerial operations. Ukraine has previously acknowledged developing and deploying naval drones as part of its military strategy.

Greek authorities have not yet released official statements about the drone's origin, how it came to be in the cave, or whether it poses any security concerns to the region. The investigation remains ongoing as officials work to determine the circumstances surrounding the discovery.

The Ionian Sea, located between Greece and Italy, is a strategically important waterway in the Mediterranean region. The discovery highlights the potential for military hardware from the Russia-Ukraine conflict to appear in unexpected locations.
