On Wednesday night, several explosions were reportedly heard on other parts of the Iranian coast, including the cities of Konarak and Chabahar.

Iranian state TV reported eight explosions in Bandar Abbas, and said two missiles had hit the ports of both Sirik and Jask – also in southern Iran.

It added that two projectiles had hit the island of Abu Musa, which has been the subject of a longstanding ownership dispute between Iran and the United Arab Emirates.

Air defence systems were activated in Bandar Abbas, according to reports in Iranian state media.

The extent of damage from the US strikes is not yet known, but Iranian media have reported power cuts in Chabahar and a fire at an Islamic Revolutionary Guard Corps (IRGC) barracks in Bushehr.

Two of three power lines cut off in Chabahar had been restored quickly and a third would be operational soon, the Iranian Students’ News Agency said.

Earlier on Wednesday, Centcom wrote in a statement that it held Iran accountable for “recent unjustified aggression against commercial shipping and civilian crews freely navigating a vital international waterway.”

Speaking to reporters from Air Force One on Wednesday evening, the US president said Iran had “called a little while ago” and wanted to make a deal “so badly”.

Trump added: “I just don’t know if they’re worthy of making a deal – I don’t know that they’re going to honour the deal, that’s the problem.”

On Tuesday, the US military said it had launched “powerful” strikes in response to attacks on three tankers in the strait.

The current flare up has been the worst exchange of strikes between the US and Iran since the deal – known as a memorandum of understanding (MoU) – was signed on 17 June.

Trump said on Wednesday that the ceasefire agreement signed last month with Iran was now “over”.

He told reporters: “I don’t want to deal with them anymore, they’re scum. You know what scum is? They’re scum. They’re sick people.”

In response, Iran’s Foreign Minister Abbas Araghchi said in a post on X: “We do not answer vulgarity with vulgarity, but with action: fearlessly and with great valour.”

The deal between the US and Iran included 14 points, among them a 60-day period for a ceasefire during which negotiations should continue, the safe passage of vessels through the Strait of Hormuz and the US lifting sanctions on Iran.

The 60-day period for negotiations is not yet up, but Trump said he saw further talks as “a waste of time”.

These are not the first strikes since the MoU was signed.

The US launched a series of strikes on Iran on 26 June after an Iranian projectile hit a cargo ship in the Strait of Hormuz.

Further US strikes took place on 27 June, following an attack on a tanker. But later that month both sides had agreed to “stand down”.
