Iran said yesterday it would strike the energy and water systems of its Gulf neighbours in retaliation if US President Donald Trump follows through with a threat delivered a day earlier to hit Iran’s electricity grid in 48 hours, escalating the three-week-old war.
The prospect of tit-for-tat strikes on civilian infrastructure could further rattle global markets when they reopen this morning, and threaten the livelihoods of millions of civilians in the region who rely almost exclusively in some cases on desalination plants for water.
Air raid sirens sounded across Israel from the early hours of yesterday, warning of incoming missiles from Iran, after scores of people were hurt overnight in two separate attacks in the southern Israeli towns of Arad and Dimona.
The Israeli military said hours later that it was striking Tehran in response.
Trump issued his warning on Saturday evening, less than a day after signalling the United States might be considering winding down the conflict, even as US Marines and heavy landing craft are heading to the region.
If Iran’s fuel and energy infrastructure is attacked by the enemy, all energy infrastructure, as well as information technology...and water desalination facilities, belonging to the US and in the region will be targeted pursuant to previous warnings,” Iranian military spokesman Ebrahim Zolfaqari said, according to state media.
Iran’s Parliament Speaker Mohammad Baqer Qalibaf doubled down, writing on X that critical infrastructure and energy facilities in the Middle East could be ‘irreversibly destroyed’ should Iranian power plants be attacked.
Iran’s Revolutionary Guards said they would also mean the shipping lane where a fifth of global oil and liquefied natural gas normally transits along Iran’s southern coast would remain shut.
“The Strait of Hormuz will be completely closed and will not be opened until our destroyed power plants are rebuilt,” the Guards said in a statement.
More than 2,000 people have been killed during the war the US and Israel launched on February 28, which has upended markets, spiked fuel costs, fuelled global inflation fears and convulsed the postwar Western alliance.
“President Trump’s threat has now placed a 48-hour ticking time bomb of elevated uncertainty over markets,” said IG market analyst Tony Sycamore, who expects stock markets to fall when they reopen.
Oil prices jumped on Friday, ending the day at their highest in nearly four years.
Markets already under severe strain from blockaded shipping were further rattled last week when Israel attacked a major gas field in Iran, and Tehran responded with strikes on neighbours, raising the prospect of damage hindering energy output even if tankers resume sailing.
Iranian attacks have effectively closed the Strait of Hormuz, causing the worst oil crisis since the 1970s.
Its near-closure sent European gas prices surging as much as 35 per cent last week.
“If Iran doesn’t FULLY OPEN, WITHOUT THREAT, the Strait of Hormuz, within 48 HOURS from this exact point in time, the United States of America will hit and obliterate their various POWER PLANTS, STARTING WITH THE BIGGEST ONE FIRST!” Trump posted on social media on Saturday.
Iranian media quoted the country’s representative to the International Maritime Organisation as saying the strait remains open to all shipping except vessels linked to ‘Iran’s enemies’.
Ali Mousavi said passage through the waterway was possible by co-ordinating security and safety arrangements with Tehran.
Ship-tracking data shows some vessels, such as Indian-flagged ships and a Pakistani oil tanker, have negotiated safe passage through the strait. But the vast majority of ships have remained holed up inside.
The United States and Israel say they have seriously degraded Iran’s ability to project force beyond its borders with their three weeks of intensive air strikes.
But Tehran fired its first known long-range ballistic missiles with a range of 4,000km on Friday towards a US-British Indian Ocean military base, expanding the risk of attacks beyond the Middle East.
An Iranian strike also landed near Israel’s secretive nuclear reactor about 13km southeast of the city of Dimona.
The war has been taking place alongside a confrontation on a separate front between Israel and Lebanon’s Hizbollah, backed by Iran, with Israel saying yesterday its troops had raided a number of the armed group’s sites in southern Lebanon.
Israeli military spokesperson Brigadier General Effie Defrin told reporters Israel continues to hit Iran nonstop and expects ‘weeks more of fighting against Iran and Hizbollah’.
Hizbollah said it had attacked several border areas in northern Israel. Israeli emergency services said one person was killed in a kibbutz near the border. Israel later said it was checking whether the death was caused by Israeli fire.
Hizbollah has fired hundreds of rockets at Israel since it entered the regional war on March 2, prompting an Israeli offensive that has killed more than 1,000 people in Lebanon.
Pope Leo appealed for an end to the conflict. “The death and suffering caused by this war are a scandal to the whole human family,” he said.
A Reuters/Ipsos poll conducted last week found 59pc of Americans disapprove of US strikes against Iran, while 37pc approved.
The war has become a major political liability for Trump ahead of November elections for Congress.
