A senior US official told Fox News on Thursday that the US military struck Iran’s Qeshm Port and Bandar Abbas.
The official stressed, however, that the attacks do not signal a renewed war.
Later, a senior US official told Fox News that the US military also struck Iran’s Bandar Kargan naval checkpoint in Minab.
Meanwhile, the Iranian Tasnim news agency reported that the Iranian Navy attacked three US destroyers near the Strait of Hormuz with missiles and drones.
“The destroyers of the terrorist US force are fleeing towards the Sea of Oman. The attack on the hostile American destroyers was carried out by missiles and suicide drones," the report said.
The Khatam al-Anbiya Headquarters of the Iranian military claimed in an official statement that the United States violated the ceasefire by attacking Iranian vessels.
"We will respond to any attack with force and without any hesitation," the statement read.
US Central Command (CENTCOM) issued an official statement, saying, “US forces intercepted unprovoked Iranian attacks and responded with self-defense strikes as US Navy guided-missile destroyers transited the Strait of Hormuz to the Gulf of Oman, May 7."
“Iranian forces launched multiple missiles, drones and small boats as USS Truxtun (DDG 103), USS Rafael Peralta (DDG 115), and USS Mason (DDG 87) transited the international sea passage. No US assets were struck," said CENTCOM.
It added that the US Army “eliminated inbound threats and targeted Iranian military facilities responsible for attacking US forces including missile and drone launch sites; command and control locations; and intelligence, surveillance and reconnaissance nodes."
“CENTCOM does not seek escalation but remains positioned and ready to protect American forces," the statement concluded.
Separately, Iran’s Mehr news agency reported that air defense systems were activated in western Tehran.
Explosions were also reported in Abu Dhabi shortly before midnight on Thursday.
Earlier, Iranian media reported mysterious explosions in the south-east of the country, near the Strait of Hormuz.
Fars News Agency, which is affiliated with the Islamic Revolutionary Guard, initially reported explosions near the port city of Bandar Abbas and Qeshm Island.
Later, Fars reported that "exchanges of fire ensued between Iranian forces and the enemy" in the area. According to the newest report, Bahman Pier, located on Iran’s Qeshm Island in the Strait of Hormuz, was the target of an attack and was struck.
The Tasnim news agency attributed the explosions to “ hostile activity by the United Arab Emirates" in the dock area on Qeshm Island.
