## Summary

On 1 June 2026 the [French](/ja/entity/france) navy boarded the tanker Tagor in Atlantic
international waters, the fourth seizure of a [Shadow Fleet](/ja/entity/shadow-fleet) vessel by France since
September 2025. Brest prosecutors opened a criminal case for failure to prove
nationality, absence of a flag and refusal to comply; the ship, falsely flying a
Cameroonian flag, was sailing from Murmansk. [Britain](/ja/entity/united-kingdom) and other
partners assisted. President Macron called sanctions circumvention "unacceptable."
Kremlin spokesman Dmitry Peskov branded the boarding "illegal" and "piracy," and
foreign-ministry spokeswoman Maria Zakharova argued UNCLOS bars forcibly diverting a
ship to the warship's home port. The seizures parallel Britain's mid-June capture of
the Smyrtos ([UK boards a sanctioned tanker and designates 27 more shadow-fleet vessels](/ja/n/uk-russia-shadow-fleet)).

## By the numbers

- 4, French shadow-fleet seizures since September 2025.
- ~600, vessels under EU shadow-fleet sanctions; ~557 after the 19th package.
- ~40%, share of the shadow fleet hit by US OFAC, vs ~two-thirds by the EU (Kpler).
- 1 yr, in-absentia jail term a French court gave the captain of the earlier Boracay.

## Why it matters

Physical interdiction raises the cost of moving sanctioned [Russian](/ja/entity/russia) crude and
shifts enforcement from paper listings to seizures, widening the Urals discount and
forcing tankers to reroute. It also opens a legal fight over high-seas authority that
Moscow is using to allege piracy.

## What to watch

- Whether courts uphold the "no flag / failure to prove nationality" boarding basis.
- Russian or insurer retaliation, and whether more tankers avoid the Channel and Atlantic.
- Coordination with the next EU package and US OFAC relistings.
