The British government sanctioned 18 tankers and four LNG carriers on Thursday with its largest package of designations yet to target the Russian shadow fleet.
The move takes the number of oil tankers targeted by the UK this year to 43. The new round includes eight vessels linked to state carrier Sovcomflot.
The government also said it was looking to challenge shadow fleet vessels with suspected dubious insurance to provide details of coverage as they pass through the English Channel.
