US launches fresh wave of strikes as Iran says civilian infrastructure hit

Centcom also said marines had boarded an oil tanker in the Gulf of Oman as part of the renewed US blockade of Iran's ports that began on Tuesday night.

It added it had "redirected 3 commercial vessels trying to run the blockade".

According to Centcom, US forces disabled nine ships and redirected more than 140 under its previous blockade of Iranian ports between 13 April to 18 June.

As the renewed hostilities further strained the preliminary deal to end the war, White House press secretary Karoline Leavitt said on Thursday that Trump remained open to talks with Iran.

"The president will hold them accountable when they turn their back on the words that they state to the United States. But he is always open to diplomacy at the very same time," she told reporters.

She said Iran has expressed it still wants to make a deal with the US, adding: "We're talking to them, but again, the president is not going to allow them to fire on ships in the strait without paying a consequence for that."

As attacks escalate, the Strait of Hormuz - a critical waterway off Iran's coast that Tehran effectively blocked in response to US-Israeli strikes - has remained shut.

That has impacted the flow of oil from the region and the head of the International Energy Agency, Fatih Birol, says he has concerns about global energy supplies.

"We should be worried, and I am worried, if the situation does not improve in the next few weeks," Birol said on Thursday night.

Earlier on Thursday, Tehran said it had struck US military bases in Jordan, Kuwait and Bahrain, while the US said it had inflicted a six-hour wave of strikes on multiple locations in the strait.

Those exchanges came after Trump warned Iran it had "better behave" or face further military action should Iran not return to negotiations.

Iran's top negotiator, Mohammad Bagher Ghalibaf, told state media that Tehran had "no reason" to abide by any agreement that did not benefit the country.

He added that Iran's national security depended on maintaining what he described as "Iranian arrangements" in the Strait of Hormuz.
