The Belgian government has detained an oil tanker identified as part of a Russian shadow fleet, a move that has garnered international attention. The operation, which involved Belgian armed forces and French defense support, was announced by Defense Minister Theo Francken via social media.
Francken reported that the tanker, named Ethera, was intercepted off the coast of Ostend and is currently being escorted to the port of Zeebrugge for further investigation. This vessel, measuring 180 meters and built in 2008, is registered under the flag of Guinea and has been on a European list since October 2025, indicating its involvement in activities that undermine sanctions against Russia.
“In recent hours, our armed forces, supported by French defense forces, boarded the oil tanker belonging to the Russian shadow fleet,” Francken stated.
The operation, dubbed “Blue Intruder,” has been described by Francken as a commendable effort by the military, emphasizing Belgium’s commitment to its NATO and European Union obligations despite its relatively small size.
“Without its shadow fleet, Putin cannot wage war against innocent Ukrainians. Thus, we are dismantling these ships, one by one, until his aggressive war ceases,” he added.
Belgian Prime Minister Bart De Wever praised the military’s decisive actions and reaffirmed the country’s adherence to international maritime law to protect its territorial waters.
“I congratulate our armed forces on their professional and decisive actions during this successful operation and thank our French partners for their crucial support. Belgium will uphold international maritime law and the security of its territorial waters,” De Wever stated.
Justice Minister Annelies Verlinden confirmed that the tanker was identified as operating under a false flag and is being directed to port for further inquiry.
“The Ministry of Defense, the General Directorate of Shipping, and the Ministry of Justice intercepted a vessel sailing under a foreign flag at sea. In times of geopolitical tension, protecting our North Sea and critical infrastructure remains paramount,” Verlinden remarked.
French President Emmanuel Macron characterized the tanker’s detention as a significant blow to Russia’s shadow fleet, asserting that European nations are resolutely focused on cutting off funding sources for Russia’s military actions in Ukraine.
“In the North Sea, our French Navy helicopters assisted Belgian forces in capturing the oil tanker under international sanctions. Europeans are determined to close off the funding sources for Russian aggression in Ukraine through sanctions,” Macron stated.
Ukrainian Foreign Minister Andrii Sybiha expressed gratitude to Belgium for the tanker’s seizure, highlighting the necessity of such actions to deprive Russia of resources for its ongoing aggression and war crimes against Ukraine.
He also thanked his Belgian counterpart, Maxim Prevot, the government, military, security forces, and partners from the G7 and Northern and Baltic countries for their commitment and professionalism in supporting this operation.
“Belgium once again demonstrates leadership in strengthening European security. We urge all partners to follow this example, resolutely countering Russia’s shadow fleet through sanctions and concrete actions, while promoting peace through strength,” Sybiha stated.
The Russian shadow fleet comprises a network of oil tankers that facilitate the circumvention of international sanctions imposed due to its aggression against Ukraine. This fleet enables the Kremlin to maintain oil exports, particularly to China and India, despite restrictions on Russian oil imports to the EU.
According to Ukraine’s Ministry of Defense Intelligence, the Russian shadow fleet consists of over a thousand tankers, including 238 actively involved in evading sanctions. These vessels frequently change flags, disable tracking systems, and operate without proper insurance, complicating their detection and identification.
The international community has been actively responding to this issue, with the European Union repeatedly expanding its sanctions lists to include vessels linked to the shadow fleet. For instance, the 15th EU sanctions package added several dozen ships involved in the illegal transportation of Russian oil.
Additionally, Australia introduced sanctions against 60 shadow fleet vessels for the first time, while Canada announced sanctions against over 200 ships used to bypass restrictions. Despite these international efforts, Russia continues to utilize its shadow fleet to further its economic interests and finance military operations.
Belgium's recent interception of an oil tanker linked to Russia's shadow fleet underscores the ongoing international efforts to enforce sanctions against Russia. This operation has garnered support from various European nations, highlighting the collaborative approach to countering Russian aggression.
