UK Identifies Legal Basis to Intercept Sanctions-Evading Vessels

The UK government has identified a legal framework enabling military intervention against vessels operating within so-called shadow fleets, which are used by countries like Russia, Iran, and Venezuela to evade international sanctions on oil exports.

Last week, British armed forces assisted U.S. troops in seizing the Marinera oil tanker, accused of transporting oil for Venezuela, Russia, and Iran in violation of U.S. sanctions. The operation involved RAF surveillance aircraft and the Royal Navy support ship RFA Tideforce.

Defence Secretary John Healey stated that the action was "in full compliance with international law," emphasizing that the UK "will not stand by as malign activity increases on the high seas."

The UK has already imposed sanctions on more than 500 alleged shadow vessels believed to be financing hostile activities, including Russia's invasion of Ukraine.

Transport Secretary Heidi Alexander announced an increase in insurance checks, with over 600 ships stopped while sailing near the British Isles. She noted that vessels not legitimately flagged often lack insurance, posing risks such as potential oil spills.

The government plans to utilize the Sanctions and Money Laundering Act of 2018 to authorize military action against these vessels, marking an escalation in efforts to enforce sanctions and disrupt illicit oil trade.
