A top Iranian military commander warned on Wednesday that the country possesses “secret weapons,” a day after Israel’s Foreign Minister said that the country is preparing for possible military involvement in any potential military escalation in the Persian Gulf, as tensions continue to rise between Iran and the United States.

“Our deterrence and secret weapons have stopped the filthy enemy 200 miles away [from the Iranian borders] in the Strait of Hormuz,” Brig.-Gen. Alireza Sabahi Fard, commander of the Iranian Army’s Khatam ol-Anbiya Air Defense Base, was quoted by Iran’s Fars News as saying on Wednesday at a forum in Tehran.

“The enemy knows very well that it should not go for testing Iran’s combat capability, as its first mistake will be its last,” he continued.
