Iran Hits US Bases in Four Nations, Endangering 21% of Oil

Iran's Revolutionary Guard struck US military bases in Kuwait, Jordan, Bahrain and Erbil early Wednesday, killing American personnel in the largest coordinated retaliation since the conflict began and sharpening the risk to the Strait of Hormuz, the waterway that carries about a fifth of the world's oil.

President Donald Trump warned Tehran it would face attacks at a "much harder and higher" level if it retaliated, saying Washington held "almost total control" of the strait. The threat frames the decision that now drives markets: whether the White House answers Iran's multi-front strike with another round, pushing the confrontation toward a wider regional war.

The Guard said its ground force hit the headquarters and accommodation of the US commander at Ali Al Salem Air Base in Kuwait with missiles and drones, setting fire to a drone hangar and ramp and destroying aircraft it said had taken part in strikes on Iran. It claimed the operation ran in parallel with attacks on US facilities in Jordan, Bahrain and Erbil, and that it killed "a number" of US personnel — claims that could not be independently verified. Jordan said its air defences intercepted 10 of 13 incoming ballistic missiles, with three landing in remote areas and no casualties reported, while Bahrain said it shot down incoming drones and Kuwait reported responding to hostile missile and drone threats.

The exchange marked the sharpest escalation in a conflict that began with US and Israeli strikes on Iran on Feb. 28 and has since swung between a June 17 memorandum of understanding and renewed hostilities. Washington's Sept. 1 operation targeted Guard air-defence systems, radar, maritime assets, mine-laying capability and communications sites across southern Iran, after CENTCOM cited attempted attacks on commercial shipping in the strait and on US service members. Iranian authorities said the strikes killed at least 12 people, including five at a wedding reception in Sirik county in Hormozgan province and seven more in Khuzestan province, drawing a warning from Supreme Leader Mojtaba Khamenei that Iran had "unforgettable lessons" for the "American enemy."

The market stakes rest on whether Washington escalates again. The Strait of Hormuz handled roughly a fifth of global oil trade before the conflict, and shipping data show commercial passage remains well below pre-conflict levels even after Trump's assertion of control. A wider war that closes or further restricts the waterway would tighten Gulf supply at a time when Iran has already pressured shipping through the strait, pushing crude prices higher and driving investors toward gold and the dollar. The last comparable flare-up, an Aug. 31 exchange in which US forces struck Iran's Larak Island and Tehran retaliated against Jordan and the UAE, ended a month-long lull in direct attacks; Wednesday's multi-front response suggests the pause has given way to a more sustained campaign rather than a one-off tit-for-tat.

Iranian commanders signaled more strikes to come. Colonel Ebrahim Zolfaghari, spokesman for the Guard's Khatam al-Anbiya Central Headquarters, said operations against US forces would continue "until they regret their crimes," while political deputy General Yadollah Javani warned Arab governments hosting American troops that bases used for attacks on Iran would face Iranian fire. President Masoud Pezeshkian, by contrast, said Tehran remained ready to return to the memorandum signed in July that briefly reopened the strait before Washington accused Iran of breaching its terms by targeting vessels that ignored Iranian-imposed shipping routes. The split between the military's escalation posture and the president's openness to talks leaves the next move with Washington, whose response will determine whether crude's risk premium widens or the two sides step back from the brink.
