(SeaPRwire) –   President Donald Trump has issued a profanity-laced ultimatum, threatening to target Iranian civilian bridges and power stations if the Strait of Hormuz is not reopened by Tuesday.

On Sunday, Trump used Truth Social to warn that Tuesday would be a day of destruction for Iran’s infrastructure, combining “Power Plant Day” and “Bridge Day.” He demanded the reopening of the waterway in aggressive terms and concluded his message with the phrase, “Praise be to Allah.”

In a subsequent update, the President specified that the deadline expires at 8 p.m. Eastern Time on Tuesday.

Speaking with Fox News on Sunday, Trump claimed that negotiations with Iranian officials were ongoing and suggested a deal might be reached by Monday. However, he cautioned that if an agreement is not finalized quickly, he is prepared to destroy various targets and seize control of the oil supply.

This is not the first time Trump has threatened Iran’s power grid, as he has previously issued similar warnings only to push back deadlines citing progress in diplomatic talks.

International humanitarian regulations forbid attacks on infrastructure vital to civilian life, and such actions can be prosecuted as war crimes. These laws also require that any collateral damage to civilians must not outweigh the direct military benefits of a strike.

The destruction of these facilities could trigger massive power outages, severely affecting medical services, water treatment, and food logistics.

Agnes Callamard, the head of Amnesty International, condemned the President’s statements as “revolting.”

In a post on X, she expressed that she was at a loss for words to describe the situation, noting that Iranian civilians would suffer most from the loss of electricity, water, and transportation, which directly threatens their right to life.

The Strait of Hormuz has been largely closed to maritime traffic since February 28, following Iranian actions that came after a joint U.S.-Israeli strike killed Supreme Leader Ali Khamenei.

Since then, Iranian retaliatory strikes have targeted regional infrastructure and U.S. military sites, causing significant disruptions to global energy markets and driving up American gasoline prices.

Iran warns of an escalating energy conflict

Iranian Parliament Speaker Mohammad Baqer Qalibaf previously countered Trump’s threats by stating that Iran would retaliate against energy and oil facilities linked to the U.S. and its allies throughout the region.

On Sunday, Iran’s joint military command reaffirmed this stance.

“We once again repeat: if you commit aggression again and strike civilian facilities, our responses will be more forceful,” a spokesperson stated in remarks published by the IRNA news agency.

Ali Akbar Velayati, a senior advisor to the new Supreme Leader Mojtaba Khamenei, also hinted at closing the Bab al-Mandab Strait, a critical passage between the Red Sea and the Gulf of Aden.

He warned on social media that if the U.S. continues its current path, it will find that global trade and energy flows can be halted instantly.

The Houthi movement in Yemen, which is allied with Iran, officially joined the regional conflict last month.

While Iran’s blockade of the Strait of Hormuz has shaken markets, the Houthis previously caused significant disruption to global shipping between late 2023 and early 2025 by attacking over 100 vessels in the Red Sea in support of Palestinians.

Thomas Juneau, a professor at the University of Ottawa and Chatham House fellow, told TIME that a return to Houthi attacks in the Red Sea would have a major impact on the global economy.

“The Houthis would cause a much more important impact on the war if they were to start targeting maritime shipping in the Red Sea and try to close the Bab al-Mandab Strait. This would amplify the war’s already strong impact on oil and natural gas prices and on the global economy,” he noted.

Hostilities in the Red Sea would likely block the Suez Canal, a route responsible for roughly 22% of the world’s container shipping trade.

Israel targets Iranian petrochemical site

Evidence suggests a limited energy war is already occurring. On Saturday, Israel conducted a strike on a major petrochemical facility in Mahshahr, Iran.

Hamed Shams of the Iranian oil ministry stated the attack damaged infrastructure that provides electricity to both the plant and 500,000 residents in the Khuzestan region.

Israeli Prime Minister Benjamin Netanyahu defended the strike, calling the facility a source of funding for Iranian-backed terrorism.

“We will continue to hit them, as I promised,” he asserted.

In response, Iranian forces reportedly struck power and petrochemical facilities in Kuwait on Sunday, including a water desalination plant. Bahrain also reported that an Iranian drone strike caused a fire at a national oil storage facility.
