As the stand-off over the Strait of Hormuz continued, following its effective blockade by Iran, the US and the gulf state are trading threats of further destruction of energy and oil infrastructure across the Middle East with US President, Donald Trump, saying Tehran would face possible obliteration of its energy facilities if it failed to reopen the channel within 48 hours.

In a swift response, Iran threatened to irreversibly destroy US-linked energy sites across the Middle East if its power plants were targeted.

The 48 hours deadline expires today.

Trump’s ultimatum came hours after two Iranian missiles struck southern Israeli towns of Arad and Dimona, injuring more than 160 people in the most destructive attack since the war began.

This, the Israeli Prime Minister, Benjamin Netanyahu, vowed to retaliate “on all fronts”.

Iran had blocked the vital waterway, which carries a fifth of global crude oil trade in peacetime, as its key leverage in the war.

The standoff has sent crude oil prices soaring, with North Sea Brent crude now trading above $105 a barrel, as long-term consequences for the global economy become an acute concern.

The ultimatum, made just a day after the US president said he was considering winding down military operations after three weeks of war, came as the key oil passage remained effectively closed and thousands more US Marines headed to the Middle East.

Iran’s foreign minister, Abbas Araghchi, said Tehran had imposed restrictions only on vessels from countries involved in attacks against Iran, and would assist others that stayed out of the conflict.

Meanwhile, issuing the threat via  his Truth Social, Trump said that the US would “hit and obliterate various Iran power plants starting with the biggest one first if Tehran did not fully reopen the strait within 48 hours.”

Reinforcing Trump’s threat, US Treasury Secretary, Scott Bessent, said the US may need to “escalate” its attacks against Iran to be able to wind down the war.

Asked on NBC’s “Meet the Press” if Trump was winding down or escalating the war, Bessent said: “They’re not mutually exclusive. Sometimes you have to escalate to de-escalate.”

“This is the only language the Iranians understand,” he argued.

Iran threatens US-linked Gulf energy sites after

In response to Trump’s threat, Iran’s army said it would target energy and desalination infrastructure belonging to the US and the regime in the region, according to the Fars news agency.

In a post on X, speaker of the Iranian parliament, Mohammad-Bagher Ghalibaf,

said that vital infrastructure, energy and oil facilities throughout the region will be considered “legitimate targets” and would be destroyed in an irreversible manner.

“Immediately after the power plants and infrastructure in our country are targeted, the critical infrastructure, energy infrastructure, and oil facilities throughout the region will be considered legitimate targets and will be destroyed in an irreversible manner, and the price of oil will remain high for a long time,” Ghalibaf said.

Similarly, Iran’s Islamic Revolutionary Guard Corps (IRGC) intelligence unit in a post on X published by the IRGC affiliated Fars News Agency, said that it is thinking “beyond just the region”.

The post explained that this referred to a “red target bank” of technological and political targets in response to threats against power plants, suggesting that action could be taken “in less than 48 hours”.

The post also lists several achievements the IRGC claimed to have made during the war, including what it described as the “consolidation of power in the Strait,” and “control of global energy.”

To completely shut down the strait

Besides the threats of targeting energy infrastructure across the region,  Iran’s military also threatened to completely shut down the strategic Strait of Hormuz if Trump acts on threats to target the country’s power plants.

“If the United States’ threats regarding Iran’s power plants are carried out… the Strait of Hormuz will be completely closed, and it will not be reopened until our destroyed power plants are rebuilt,” the military’s operational command, Khatam Al-Anbiya, said in a statement carried by state TV.

The military said it would also strike Israel’s “power plants, energy, and information and communications technology (ICT) infrastructure”, along with power plants in regional countries hosting US bases and companies with US shareholders.

It added that the measures will be taken “to defend our country and the interests of our nation”.

Iran charges $2m from ships passing through Strait of Hormuz – Iranian MP

BBC quoted Iranian Member of Parliament, Alaeddin Boroujrrdi, as saying on state TV that some of the ships that pass through the Strait of Hormuz were being charged “ a $2 (£1.5) million fee” by Iran.

He said that a “new governing regime” was being imposed in the Strait claiming that “war has costs”. According to him, the closure of the Strait shows the “authority and right that the Islamic Republic of Iran possesses”.

Iran’s deadly strikes on southern Israel injures 160

Meanwhile, retaliating against Israel’s strike on its Natanz nuclear facility, Iran struck southern Israel towns of Arad and Dimona, injuring more than 160 people in the most destructive attack since the war began. The Israel prime minister, Benjamin Netanyahu, vowed to retaliate “on all fronts”

The strikes, which slipped through Israel’s missile defence systems, tore open the facades of residential buildings and carved craters into the ground.

First responders said 84 people were injured in the town of Arad, 10 of them seriously. Hours earlier, 33 were wounded in nearby Dimona, where AFPTV footage showed a large hole gouged into the ground next to piles of rubble and twisted metal.

Dimona hosts a facility widely believed to be the site of the Middle East’s only nuclear arsenal, although Israel has never admitted to possessing nuclear weapons.

The Israeli army told Agence France-Presse there had been a direct missile hit on a building in Dimona, with casualties reported at multiple sites, including a 10-year-old boy in serious condition with shrapnel wounds.

Iran said the targeting of Dimona was retaliation for Israeli strikes on its Natanz nuclear facility, with the IRGC saying forces also targeted other southern Israeli towns as well as military sites in Kuwait and the UAE.

The Natanz facility hosts underground centrifuges used to enrich uranium for Iran’s disputed nuclear programme; it sustained damage in the June 2025 war.

The Israeli military denied it was behind the Natanz strike, but said it had struck a facility at a Tehran university that it claimed was being used to develop nuclear weapon components for Iran’s ballistic missile programme.

Attacks on nuclear sites create escalating threat to public health, WHO chief warns

The Iran war has reached a “perilous stage” as both sides target nuclear facilities, the Director-General of the World Health Organisation, Tedros Adhanom Ghebreyesus, has warned.

Ghebreyesus said the International Atomic Energy Agency was looking into both attacks.

“No indications of abnormal or increased off-site radiation levels have been reported,” he said in a post on X.

But he added: “Attacks targeting nuclear sites create an escalating threat to public health and environmental safety.

“Since the outbreak of hostilities, WHO has provided critical training to its own staff and UN personnel across 13 countries to help them respond effectively to public health threats in the event of a nuclear incident.

“I urgently call on all parties to exercise maximum military restraint and avoid any actions that could trigger nuclear incidents.

“Peace is the best medicine.”
