The US Treasury Department sanctioned a Greek shipper it said facilitated the transport of Iranian oil, broadening the Trump administration’s maximum-pressure campaign against Tehran and a crackdown on its so-called shadow fleet.
Antonios Margaritis was designated along with a web of companies overseen by him in Greece and the Marshall Islands. The move comes weeks after US Treasury’s biggest Iran sanctions action in seven years, which targeted a network overseen by oil tycoon Hossein Shamkhani, whose father is a senior adviser to Supreme Leader Ayatollah Ali Khamenei.
