The targeted ship, identified as the Tagor, was discovered flying a false flag roughly 400 nautical miles west of Brittany in international waters.
President Macron strongly defended the military action on social media, stating that it is entirely unacceptable for vessels to circumvent international sanctions, violate the law of the sea, and generate funds to fuel Russia’s war against Ukraine, which has now spanned more than four years.
The Kremlin reacted with fierce condemnation following the operation, with spokesman Dmitry Peskov labeling the interception an “illegal” act that borders on international piracy.
Peskov added that Moscow is actively taking measures to ensure the safety and security of its maritime cargo. Since launching its full-scale invasion of Ukraine in 2022, Russia has heavily relied on a secretive “shadow fleet” of tankers featuring obscure ownership structures specifically designed to bypass global restrictions placed on its oil exports.

The capture of the Tagor marks the fourth shadow fleet vessel boarded by French authorities since September 2025. While previous infractions resulted in financial fines before the ships were released, European authorities have vowed to permanently block and seize them moving forward.
The high-seas interception underscores a hardening stance by Western allies against illicit Russian maritime transport. UK Prime Minister Sir Keir Starmer previously granted authorization for British military personnel to board sanctioned Russian vessels.
Despite the UK Ministry of Defence asserting that it is actively disrupting and deterring these operations, recent data suggests that nearly 200 shadow fleet vessels have bypassed restrictions to enter UK waters since mid-March.
President Macron reiterated that the Tagor operation was executed in strict compliance with international maritime laws, warning that these unregulated ghost ships fail to adhere to basic navigation guidelines, thereby posing severe environmental risks and safety threats to global waterways.
