The Greek military is examining a mysterious unmanned naval drone spotted in the Ionian Sea by local fishermen.
They found the vessel in a cave near the island of Lefkada on Thursday and alerted the coast guard, which then towed it to the nearby port of Vasiliki. The Greek defence ministry is now overseeing the investigation.
Reports in Greek media say the drone carried explosives and its engine was still running when it was discovered. The reports also suggest vessel could be either Ukrainian-made or linked to the ongoing Russia-Ukraine war.
The BBC has approached both Greece's and Ukraine's military for official comment.
Footage on social media has emerged showing a Greek coast guard boat towing the several metre-long drone to the port.
