The Group of Seven democracies have sought to crimp Russia’s oil export earnings that help fund the war against Ukraine.

Finland says a ship affiliated with Russia's "shadow fleet" is linked to a 60-mile-long anchor drag mark on the seafloor. A power cable in the Baltic Sea was severed last week.

"The United States is taking sweeping action against Russia's key source of revenue for funding its brutal and illegal war against Ukraine," Treasury Secretary Janet Yellen said.
