France and its allies have detained a sanctioned Russian oil tanker in the Atlantic over the weekend, President Emmanuel Macron said on Monday.

Axar.az informs, citing France 24, the Tagor was detained on Sunday morning in international waters with the help of Britain and other partners, he said in a social media post, adding: "It is unacceptable for ships to circumvent international sanctions, violate the law of the sea, and fund the war that Russia has been waging against Ukraine for more than 4 years."

This is the latest of several suspected "shadow fleet" tankers intercepted by France in recent months suspected of transporting Russian oil in violation of Western sanctions

A French court in March sentenced in absentia the captain of a suspected Russian shadow fleet tanker to one year in jail for failing to comply with orders to stop his ship after the French navy boarded the vessel in September 2025 before releasing it.
