A Maltese-flagged tanker has been left adrift off the coast of Alonissos, Greece, due to an engine malfunction. The vessel is carrying an unspecified cargo and is currently unmanned, posing a potential navigational hazard. The ship has a crew of 17 Turkish nationals on board. Greek authorities have been notified and are monitoring the situation closely. Efforts are underway to assess the extent of the mechanical failure and to determine the best course of action to secure the tanker. No immediate danger to the crew or the environment has been reported, but contingency plans are being prepared. A tugboat is expected to arrive on scene to attempt to regain control of the vessel and tow it to safety.
