Iran’s Islamic Revolutionary Guard Corps announced on Monday that it had carried out a multi-phase overnight operation against US military installations in Jordan, Bahrain and Kuwait, and destroyed radar systems in Oman, in what it described as retaliation for American strikes on Iranian coastal bases. The IRGC said its Aerospace Force and Ground Forces struck Prince Hassan airbase in Jordan, igniting fuel depots and ammunition bunkers; hit helicopter maintenance centres, a P-8 aircraft hangar and a drone command centre at Sheikh Isa airbase in Bahrain; and destroyed fuel tanks and Patriot air-defence systems at Ali Al Salem airbase in Kuwait, along with an FPS radar at Ahmad al-Jaber. Kuwait’s armed forces reported intercepting hostile air targets over its territory, while Jordan’s military said it shot down four missiles that had entered its airspace from Iran. Bahrain’s interior ministry activated warning sirens and urged residents to seek shelter.

Viewed from Tehran, the strikes represent the latest phase of a retaliatory campaign that the IRGC says will continue until what it calls illegal US military interference in the Strait of Hormuz ends. IRGC statements asserted that the strait is Iranian territory and that the only way to restore regular shipping is for Washington to halt its interventions. The force also claimed to have targeted a HIMARS launcher and missile storage in a fourth phase in Kuwait, and to have destroyed a long-range FPS radar and a ship-detection radar in Oman. US Central Command, meanwhile, said it had completed a new wave of offensive strikes against dozens of Iranian military targets, including air-defence systems, coastal radar, missile and drone capabilities, and small vessels, using fighter aircraft, warships and one-way attack drones. President Donald Trump, in a brief telephone interview, said of the operations: “We’re giving them a beating.”

The immediate consequence has been a further disruption of maritime traffic through the Strait of Hormuz, a corridor that before the war carried roughly one-fifth of global oil and liquefied natural gas shipments. Brent crude rose 4.3 per cent to $79.31 a barrel on Monday. Iran’s newly created Persian Gulf Strait Authority said passage was not currently possible because of recent US military movements, while a US-led maritime information centre maintained that an expanded southern route near Oman remained available. The IRGC warned that continued interference could trigger larger incidents in the global oil and gas sector.

The exchanges are the latest in a conflict that began with US and Israeli strikes on Iran in late February. A provisional agreement signed last month had aimed to reopen the strait and end the war after 60 days of negotiations, but Mr Trump has since said he considers the ceasefire over, though he left the door open to further talks. Iran’s lead negotiator, Mohammad Baqer Qalibaf, posted that the era of unilateral deals was finished. With the IRGC pledging to sustain its operations and US forces remaining on alert to safeguard freedom of navigation, no new diplomatic initiative has been announced.
