Six weeks into the U.S.-Israel war on Iran, there was little progress toward peace Sunday, when Donald Trump ramped up anti-Tehran rhetoric and announced the rescue of a downed airman in Iran in a high-risk operation that averted a potential crisis.

Trump announced the rescue in the early hours of Sunday in a social media post that ⁠described the operation, in a mountainous area of Iran, as "one of the most ⁠daring Search and Rescue Operations in U.S. History."

The airman, the weapons officer of an F-15 jet shot down Friday, was wounded but "will be just fine", Trump said in a message on X posted by Press Secretary Karoline Leavitt. The pilot of the aircraft was rescued Friday.

A U.S. official said ​the operation, which Israel said it had assisted, involved dozens of military aircraft and encountered fierce resistance from Iranian forces.

Iran's ​military ⁠said several U.S. aircraft were destroyed during the operation, including two military transport planes and two Black Hawk helicopters.

Footage posted on social media showed burned-out aircraft wreckage, which Reuters verified was in the area.

'Deception campaign'

A U.S. official told Reuters that the U.S. forces had to destroy at least one of the aircraft used in the rescue mission because it had malfunctioned.

The Wall Street Journal reported that two specially equipped MC-130Js aircraft used to carry out covert infiltrations and to remove troops from beyond enemy lines were blown up by U.S. forces after malfunctioning.

A senior administration official in Washington said the rescue had involved a CIA deception campaign spreading word inside Iran that U.S. forces had already found the missing airman and were moving him on the ground for exfiltration out of the country.

While the Iranians were confused and uncertain of what was happening, the missing weapons officer was located inside a mountain crevice and rescued, the official said in a statement.

The rescue of the airman offered some good news for Trump, who has faced mounting pressure over a war that has sparked a global energy crisis and threatens lasting damage to the world economy.

On Saturday, he renewed a threat to intensify attacks ⁠on Iran's energy ⁠infrastructure, saying it had 48 hours to open up shipping lanes in the Strait of Hormuz, the vital conduit for around a fifth of the world's oil and natural gas supply, which has been largely shut down.

In an expletive-laden social media post Sunday, Trump said Iran must open the Strait "or you’ll be living in Hell - JUST WATCH!"

Adding to the pressure, a senior Israeli defence official said Israel, which attacked a major petrochemicals facility Saturday, was preparing to attack Iranian energy facilities within the next week and was awaiting approval from Washington.

But despite the heavy damage to its military and civilian infrastructure from weeks of U.S. and Israeli attacks, Iran's chokehold over Hormuz has given it a powerful weapon and Tehran showed no sign of complying with Trump's demand.

It has continued to launch missile and drone attacks against Israel and on Sunday, it underlined its ability to hit U.S. allies in the Gulf by launching a drone attack on petrochemical plants in Bahrain and Abu ⁠Dhabi.

The Revolutionary Guards warned that more attacks would follow if civilian targets in Iran were hit.

Peace efforts fruitless

Opinion polls show the war is viewed with skepticism by a majority of Americans, with the risks to U.S. service personnel among their major concerns, along with regional stability and the impact on their own finances.

The war, which has spread into Lebanon, where Israel has resumed its campaign against the ​Iranian-backed Hezbollah, has killed thousands, mainly in Iran and Lebanon, where a Lebanese soldier was killed Sunday.

But efforts brokered by Pakistan to bring the two sides to an agreement ​have so far been fruitless. Iran's Foreign Minister Abbas Araghchi said Tehran demanded a permanent halt to the U.S. and Israeli campaign launched on Feb. 28.

"What we care about are the terms of a conclusive and lasting END to the illegal war that is imposed on us," he said in a message ⁠on X.

As the war ‌has continued, the ‌damage to vital economic infrastructure in Iran and neighbouring Gulf countries has mounted and the impact is set to be ⁠felt months and even years after the fighting ends.

With oil coming through Hormuz down to a trickle, ‌ministers from OPEC oil-producing countries were due to meet Sunday. But the blockade of the Strait and the damage to infrastructure meant that an immediate boost to oil production was not considered possible.

Israel and the U.S. have hit ​military and civilian infrastructure across Iran, including areas near its ⁠Bushehr nuclear plant, which Iran said posed a serious risk of radioactive contamination.

But they have not managed to suppress Iran's ability ⁠to strike back and Iranian drone attacks have continued against industrial infrastructure in the Gulf, including oil facilities, a major aluminium plant and petrochemical sites in recent days.

Earlier, Iran ⁠also attacked an Israel-affiliated vessel with a drone ​in the Strait, setting the ship on fire, state media said, citing the commander of the Revolutionary Guards' navy.
