MIAMI—The Trump administration has seized the cargo of four tankers it was targeting for transporting Iranian fuel to Venezuela, U.S. officials said Thursday, as it steps up its campaign of maximum pressure against the two heavily sanctioned allies.
Last month, federal prosecutors in Washington filed a civil forfeiture complaint alleging that the sale was arranged by a businessman, Mahmoud Madanipour, with ties to Iran’s Revolutionary Guard Corps, a U.S.-designated foreign terrorist organization. At the time, sanctions experts thought it would be impossible to enforce the U.S. court order in international waters.
