PARIS (AP) — French President Emmanuel Macron said Wednesday that an oil tanker off the French coast had committed “very serious wrongdoings” and linked it to Russia’s shadow fleet, which is avoiding Western sanctions over Moscow’s war in Ukraine. The tanker was sailing last week off the coast of Denmark and was cited by European naval experts as possibly being involved in drone flights over the country. He didn’t elaborate and France’s maritime authorities did not immediately respond to a request for details. Macron said the incident highlights “the existence and the reality of a phenomenon that we have been describing and denouncing for a long time” that is “these notorious shadow fleet” that represents tens of billions of euros for Russia’s budget and finances an estimated 40% of Russia’s war effort. Macron said between 600 and 1,000 ships are transporting Russian oil and gas despite Western sanctions.
