Iran said on Monday that its navy issued a resolute and swift warning, deterring an enemy warship from entering the Strait of Hormuz.
Tehran said the U.S. frigate, which had set sail near Iran's southern port city of Jask to cross the Strait of Hormuz "in violation of the traffic and shipping security," was hit after ignoring the Iranian naval forces' warning.
Iran also said that because of the attack, the frigate was forced to retreat and flee from the region.
No further details on the extent of the damage and casualties have been released.
The U.S. Central Command on Monday denied the Iranian claim. It said in a post on X that "no U.S. Navy ships have been struck."
Iran tightened its grip on the Strait of Hormuz beginning Feb 28, when it barred safe passage to vessels belonging to or affiliated with Israel and the United States following joint strikes on Iranian territory.
The United States imposed its anti-Iran blockade on the Strait of Hormuz after post-ceasefire negotiations with Tehran in Pakistan's capital, Islamabad, on April 11 and 12 failed to lead to an agreement.
