French President Emmanuel Macron has declared "very serious wrongdoings" by an oil tanker immobilized off the French coast, linking it to Russia's "shadow fleet" evading sanctions. The vessel, which previously sailed off Denmark and is suspected of involvement in drone flights, was boarded by French naval forces. A judicial investigation is underway for the crew's refusal to cooperate and failure to declare the ship's nationality. The incident underscores ongoing concerns about the shadow fleet's impact on global maritime security and Russia's financing of its war efforts.
