PARIS (Reuters) – Group of Seven (G7) leaders said on Sunday that western allies had decided to cut off “certain Russian banks” from the worldwide interbanking communication system called SWIFT. The statement, in a joint declaration published by the French presidency, did not specify which Russian banks would be affected. It added a transatlantic task force will soon be put in place to coordinate sanctions against Russia. (Reporting by Tassilo Hummel; Editing by Andrew Cawthorne)
