New York-listed tanker owner International Seaways has hit back at John Fredriksen’s criticism of its management and, like the shipping magnate in his open letter earlier on Tuesday, it pulled no punches.

International Seaways questioned why Fredriksen and his Seatankers Group is “targeting” two women who serve on the company’s board and are standing for re-election. The shareholder had said it will “withhold” its votes for the two at an annual general meeting on 6 June.
