The U.S. military announced on Wednesday that it has fully enforced a naval blockade on Iranian ports, effectively halting all maritime trade to and from Iran.

U.S. Central Command (CENTCOM) chief General Brad Cooper said in a statement that “the naval blockade on Iranian ports has been fully implemented,” adding that U.S. forces maintain maritime superiority in the Middle East.

He noted that an estimated 90% of Iran’s economy depends on international maritime trade, stating that “within less than 36 hours of the blockade’s enforcement, all sea-based trade to and from Iran has been completely stopped.”

The move comes amid escalating tensions between the United States and Iran, with significant implications for global shipping routes and energy markets.
