U.S. Navy carrier group has entered the area, where Iran is carrying out its naval exercises in the Strait of Hormuz, Fars reported.
Local media reported the arrival of the U.S. aircraft carrier battle groups quoting a representative of Iranian Navy.
American aircraft carrier accompanied by a group of warhips entered the area following the statement of the 5th U.S. Fleet that "no disruption by Iran in the free flow of goods through the Strait of Hormuz will be accepted".
Iran's navy commander said Wednesday that Iran could easily block oil flows through the Strait of Hormuz, a vital transit route for Persian Gulf oil, if Western governments impose further sanctions on the Islamic state for lack of cooperation with the international community on its nuclear programme.
Iranian Vice President Mohammd-Reza Rahimi was quoted on Tuesday by that country's official news agency that if Western nations sanctioned Iranian oil, "then we would not allow one drop of oil to cross the Strait of Hormuz."
Rhetoric on both sides has appeared to sharpen in recent days, as just a week ago Iran's Foreign Ministry said Tehran had no plans to close the strategic waterway.
