Tangsiri said Iran had full control of the Gulf and the Strait of Hormuz that leads into it. Closing the strait would be the most direct way of blocking shipping.

"We can ensure the security of the Persian Gulf and there is no need for the presence of aliens like the U.S. and the countries whose home is not in here," he said in the quote, which appeared in English translation on Tasnim.

He added, "All the carriers and military and non-military ships will be controlled and there is full supervision over the Persian Gulf. Our presence in the region is physical and constant and night and day."
