"The IRGC Navy has a full control over the entrance and exit of vessels in the Strait of Hormuz, we question all ships, vessels and military ships which enter the Strait of Hormuz about their destination, type of vessel, nationality, etc," Tangsiri said on Tuesday.
He further stressed that Iran has the upper-hand in the Persian Gulf because of having several strategic islands in the waterway.
The commander, however, described the presence of the trans-regional forces in the Persian Gulf as "challenging", and said that the alien vessels in the region undermine security in the Persian Gulf and are a potential danger to its environment.
"Environmental hazards are one of the dangerous consequences of the aliens' presence in the region. For example if something happens for their nuclear warships, a disaster will happen, because the Persian Gulf is a closed gulf and any pollution and contamination will cause an environmental crisis in the region which may last for years."
Last month, the IRGC established a new Navy zone in the Persian Gulf waters in a bid to boost defensive measures in waters surrounding Iran's islands.
The IRGC's fifth naval zone, namely Emam Mohammad Baqer (PBUH), was officially inaugurated in Iran's Southern port city of Bandar Lengeh in Hormozgan province in a ceremony attended by IRGC Commander Major General Mohammad Ali Jafari.
During the ceremony, Admiral Ali Ozmayee, the former commander of the IRGC's first naval zone, was appointed as the commander of the fifth zone.
The fifth zone operations will cover an area from Qeshm island and Naze'aat Islands region to the western waters of the Kish island.
Meantime, Commander of the IRGC Navy Rear Admiral Ali Fadavi said that "the fifth naval zone was started to provide operational coverage for the Naze'aat Islands, bring about a turning point and start a new trend in the region".
The IRGC first naval zone will only and specifically be tasked with maintaining security in the strategic Strait of Hormuz.
Iran has threatened to close the strategic Strait of Hormuz at the entrance to the oil-rich Persian Gulf if its nuclear program is targeted by air strikes that Israel and the United States reserve as an option.
Situated between the Gulf of Oman and the Persian Gulf, the Strait of Hormuz is a passageway for 40% of the world's oil production, including much of the crude extracted in Saudi Arabia.
