Secretary of Iran’s Supreme National Security Council, Mohsen Rezaei, warned on Tuesday that Tehran would respond to what it calls US “economic warfare” by imposing a maritime exclusion zone across the Persian Gulf.

“Economic warfare will be met by a maritime exclusion zone across the Persian Gulf to the blockade perimeter,” said Rezaei, adding the zone would extend to the edge of the US naval blockade currently in place around Iranian ports.

“In recent days, Washington has received a clear warning from Iran’s new missiles,” Rezaei said in a post on X. Rezaei stated that the country’s military posture toward American forces had been “fundamentally recalibrated.”

Rezaei was likely referring to the Qassem Basir ballistic missile that Iranian media reported was fired at US warships near the Strait of Hormuz. The US military said its warships evaded any missile attacks.
