TEHRAN - A top Iranian military commander said on Thursday the country's navy has warned a nuclear-powered US submarine to surface while it was passing through the Strait of Hormuz.

Iranian Army's Navy Commander Shahram Irani made the remarks in an interview with state-owned IRIB TV's News Network, without elaborating on the date of the event.

Iran's Fateh (Conqueror) submarine detected the the American submarine Florida, through a set of maneuvers, and forced it to surface while the latter was approaching the Strait of Hormuz in "complete silence", he added.

Iran warned the US submarine as it had entered the Iranian territorial waters "to some extent", Irani said, adding the US submarine, accompanied by an escort ship, then corrected its course and continued its journey.

The Americans should explain why did their submarine violate Iran's maritime borders and international maritime laws in an important strait, Irani said, calling on the US to observe all international regulations from now on.

He said Iran will pursue the case through international bodies and organizations, warning that such an "illegitimate and dangerous" presence by the United States poses a challenge to everyone.

The US Navy said last week the nuclear-powered guided-missile submarine Florida was operating in the Middle East to support the Bahrain-based US Fifth Fleet.
