A French government press release notes that the cargo tanker DELIVER, which came from Primorsk on Russia's Baltic Sea coast, was flying a Cameroonian flag, which they suspect was a false flag."After the visit team boarded, examination of the documents confirmed doubts about the regularity of the flag flown," reads the press statement.More European countries are boarding ships suspected of being part of the shadow fleet, with Sweden, the U.K., and France all intercepting ships in June. After agreeing on new sanctions listings on June 15, the EU is expected to finalize its 21st sanctions package in July.
