Iranian parliament speaker Mohammad Bagher Ghalibaf warned on Sunday that any U.S. strike on Iran's power plants would trigger the "irreversible destruction" of critical energy and oil infrastructure across the entire region.
As Iranian state media published a poster showing the locations of power plants in the United Arab Emirates (UAE), Qatar, Saudi Arabia, and Kuwait, warning the region "will go dark."
Responding to Trump's 48-hour ultimatum threatening to strike Iran's power plants if the Strait of Hormuz is not fully reopened, Ghalibaf wrote on X: "Immediately after power plants and infrastructure in our country are targeted, vital infrastructure as well as energy and oil infrastructure across the entire region will be considered legitimate targets and will be irreversibly destroyed, and oil prices will rise for a long time."
Semi-official Mehr News Agency published a poster headlined "Farewell to Electricity," showing a map of power plants in the UAE, Qatar, Saudi Arabia and Kuwait.
"At the slightest attack on Iran's electrical infrastructure, the region will be plunged into darkness," the poster said.
Trump issued the ultimatum Saturday night on Truth Social, threatening to "hit and obliterate" Iran's power plants, "starting with the biggest one first," if Iran did not fully reopen the Strait of Hormuz within 48 hours, setting a deadline of approximately 11:44 p.m. GMT on Monday.
The Islamic Revolutionary Guard Corps (IRGC) had already warned that any strike on Iran's fuel and energy infrastructure would result in retaliatory strikes on all U.S. and Israeli energy, IT, and desalination infrastructure in the region.
The current escalation followed a joint U.S.-Israeli offensive on Iran, which has killed over 1,300 people since Feb. 28.
Tehran has retaliated with drone and missile strikes targeting Israel, along with Jordan, Iraq, and Gulf countries, which it says are targeting "U.S. military assets."
