All commercial vessels are obliged to take the Iranian-designated maritime route for safe passage through the Strait of Hormuz or face the consequences, Iran’s military headquarters warns according to Al Jazeera.

“Any US interference in the Strait of Hormuz will be met with a decisive and swift response from the armed forces,” the Khatam al-Anbiya Central Headquarters said in a statement.

“The Strait of Hormuz is not the playground of the aggressor America, but rather the territory of the undisputed sovereignty of the Islamic Republic of Iran.”

The Fars News Agency quoted the statement as saying: “The security and maintenance of the stability of this vital waterway are the red line of the powerful armed forces of Islamic Iran.”
