What Happened?

On January 7, 2026, the United States European Command announced that US forces had seized the oil tanker Marinera, previously named Bella-1, under a warrant from a US federal court for violating United States sanctions. The vessel was intercepted in the North Atlantic Ocean after being tracked for weeks by the US Coast Guard and other military units. Reuters

This capture took place far from the territorial waters of any single country.

Russia’s Official Reaction

Russia’s Ministry of Transport released a statement asserting that the tanker had been granted a temporary permit to sail under the Russian flag and was operating in accordance with Russian and international law. The ministry argued that under the **1982 **United Nations Convention on the Law of the Sea, freedom of navigation applies in international waters, and no state may use force against a vessel duly registered under another state’s jurisdiction.

A senior Russian lawmaker described the US action as “outright piracy”, further escalating diplomatic tensions. Reuters

US Position
