Iran's Hormozgan provincial authorities said no impacts or strikes had hit the districts of Bandar Abbas, Qeshm and Sirik, in a statement carried by Entekhab on July 8, citing Tehran Municipality-controlled Mehr.

The denial points to the confusion surrounding the scale of US strikes on southern Iran, as provincial officials sought to play down reports of explosions along a stretch of coast central to shipping through the Strait of Hormuz.

News sources had reported hearing several explosions in the cities of Bandar Abbas and Sirik on the evening of July 8, with secondary strikes reported on Chabahar and Konarak, IRGC-linked Tasnim reported.

The sounds were faint and not heard in most parts of the cities, making their exact nature difficult to determine, and any noises heard in Bandar Abbas may have been related to fire directed at hostile targets. Explosions were also heard from the direction of the sea near the western coast of Sirik.

The provincial authorities said no impacts or strikes had occurred in the three districts and that efforts to obtain further information were continuing.

US forces struck several points in Iran's southern provinces, including Bandar Abbas, Qeshm and Sirik, the previous night, which were met with a response from Iranian armed forces, according to the report. The claims could not be independently verified.

The exchange followed the collapse of a ceasefire agreed last month. The US Treasury revoked a licence allowing sales of Iranian oil after three commercial ships were struck in the Strait of Hormuz, and US Central Command said it had struck more than 80 Iranian targets, including air defence systems and coastal radar sites.

Iran's Islamic Revolution Guards Corps said it had retaliated with missile and drone strikes on 85 US military sites in Bahrain and Kuwait.

Iran's Khatam al-Anbia Central Headquarters warned that any base supporting US operations against Iranian territory would be a legitimate target, while chief negotiator Mohammad Bagher Ghalibaf accused Washington of major violations of the memorandum, citing the reinstatement of oil sanctions and attacks on southern Iran.

US President Donald Trump said the ceasefire was over, telling reporters at the Nato summit in Ankara that as far as he was concerned it had ended. Iran and the US had signed the memorandum last month to extend the ceasefire for 60 days, following months of conflict that began with US-Israeli strikes on Iran on February 28.

Bandar Abbas, at the mouth of the Strait of Hormuz, is one of Iran's most important sites for imports and exports and has been struck repeatedly during the conflict.
