The US government has imposed sanctions on two companies and four vessels for allegedly transporting commodities to the benefit of Iran’s Revolutionary Guards Corps and the Houthis in Yemen.

United Arab Emirates-based Global Tech Marine Services is accused of managing and operating an aframax, as well as one MR and one LR product tanker involved in supporting Sa’id al-Jamal — a commercial organisation that the US says generates revenue for the Revolutionary Guards and the Yemeni rebel group that is attacking shipping in the Red Sea.
