Russia’s Sovcomflot (SCF Group) will appeal against the sanctioning of four of its tankers, accusing the US of unfairly targeting the company.

The US blacklisted three SCF Group-controlled tankers last week for alleged oil price cap breaches. A fourth ship from the Russian state-owned fleet was listed in October.

The SCF Group comments came as one of its sanctioned tankers halted mid-voyage to India and has idled off the coast of Sri Lanka since Saturday, according to ship-tracking data.
