The United States says it has seized two tankers linked to Venezuelan oil exports in back-to-back operations in the North Atlantic and the Caribbean.

US forces boarded the Russian-flagged Marinera after a pursuit lasting almost two weeks as it travelled through waters between Iceland and Scotland, with logistical support from the British Navy.

A second tanker, M/T Sophia, was accused by the US of conducting illicit activities and was also boarded in the Caribbean.

This move comes as the US seeks to cut off most exports of Venezuelan crude oil, just days after special forces reportedly seized Venezuelan President Nicolás Maduro in a lightning raid on his residence in Caracas.

Defence Secretary Pete Hegseth stated on X: The blockade of sanctioned and illicit Venezuelan oil remains in FULL EFFECT - anywhere in the world. Moscow condemned the seizure of the Russian-flagged ship, requesting humane treatment and rapid return of its crew.

The White House labeled the Marinera as a stateless vessel deemed illegitimate after sailing under a false flag. Reports indicated that Russia attempted to provide protection for the tanker, but US forces successfully boarded without incident.

Venezuela’s government is reportedly collaborating with the US regarding the second seized tanker, according to Secretary of State Marco Rubio, who noted that cooperation is vital for Venezuela to manage oil exports while avoiding an economic collapse.

US President Donald Trump claimed that Venezuela would be turning over significant amounts of oil to the US, stating that the administration has a coherent plan for dealing with the nation's future.

The operations reflect escalating US actions against Venezuelan oil exports amid international condemnation from nations like China, which accused the US of jeopardizing global energy security.
