The French Navy intercepted the tanker DF Peak south of Réunion for suspected illicit fuel transport, with authorities noting it may be sailing under a false Benin flag and possibly part of Russia's 'ghost fleet' used to evade sanctions.

DF Peak is listed under the Benin flag and has been on EU sanctions lists since at least mid-2024 after previously being known as Kaliningrad, a name-change pattern common in vessels tied to sanctioned activity.

There are more than 700 ships on the European Union sanctions list related to Russia's hydrocarbons, with fleet items frequently changing names or flags to bypass restrictions.

The operation aligns with Western efforts to enforce sanctions against Russia over its war in Ukraine.

A formal report was filed with the Saint-Denis prosecutor under maritime court jurisdiction, and authorities are continuing checks.

French President Macron said the action demonstrates determination to enforce international law and combat illegal maritime trade, with the operation conducted in accordance with sea-law.

The interception occurred well outside French waters under Réunion's regional authorities, with Defence Minister Catherine Vautrin stressing that international law is non-optional and that armed forces are mobilized to enforce it at sea.

The operation highlights the geographic reach of sanctions enforcement, reaching from European waters to the Indian Ocean.

Macron framed the interception as part of a broader European push to prevent sanction circumvention amid evolving responses to Russia's actions in Ukraine.

European authorities have stepped up inspections and enforcement, including seizure and sale of assets from sanctioned vessels under certain circumstances.

The EU announced a broad new sanctions package the same day, expanding penalties to about 1,600 more individuals and entities, bringing total targets to roughly 4,600.

The incident was publicly documented with official footage from the French general staff showing the arraisonnement (interception) of the tanker.
