U.S. and Saudi military forces on Wednesday struck a series of targets in eastern Iraq identified as bases and facilities used by Iran-backed groups, following drone attacks on Saudi oil infrastructure earlier in the week. Riyadh and Washington said the sites had been used to direct the drone strikes; the action has raised fresh fears of a wider escalation in the region.
The strikes came on the same day Iran’s Islamic Revolutionary Guard Corps said its forces had engaged three oil tankers in the Strait of Hormuz, forcing them to stop after issuing warnings that the vessels had taken an "unsafe and illegal route." The IRGC Navy added that it continued to assert control over the strategic waterway and warned that what it called "unlawful U.S. military interference" and instructions to vessels in the region would not go unanswered. The Guards account could not be independently verified.
U.S. Central Command said the strikes in eastern Iraq followed reports that air defences had thwarted a surprise Iranian attack on U.S. troops in the region earlier the same day. The Revolutionary Guards said it had also fired several ballistic missiles at U.S. military installations in Jordan. Recent exchanges have undone a brief pause in hostilities that followed an aborted U.S. bombing campaign and an apparent reciprocal restraint by Iran.
Sequence of attacks and responses
Saudi Arabia reported that its air defences had destroyed several drones targeting oil facilities in the kingdom's Eastern Province. Saudi defence officials said the drones were launched from Iraqi territory by Iran-backed militias. Later, U.S. Central Command and Saudi Arabia's defence ministry said the two countries carried out strikes on multiple sites across eastern Iraq that they said had been used by Iranian elements to direct drone operations.
The Saudi Defence Ministry framed its action as responsive rather than escalatory, saying it did not seek a wider confrontation but would respond to any "aggression." At the same time, Iraq's Popular Mobilisation Forces - an umbrella group of mainly Iran-aligned militias integrated into Iraq's security architecture - said a number of its official headquarters in various parts of the country were hit by what it described as U.S. and Saudi attacks. Preliminary reports cited by the PMF indicated that several people were killed and others wounded, and that damage was sustained at multiple buildings and facilities.
Market reaction was immediate: oil prices rose by more than $3 a barrel on Wednesday as traders weighed the risk that the conflict could spread and disrupt supplies.
Iran's denials and continued warnings
Speaking on state television, an Iranian defence official strongly denied any connection between projectiles fired from other countries toward Saudi targets and Iran's forces. The unnamed official, quoted by the state broadcaster, said attributing attacks on U.S. interests in the region to Iran would be a "major miscalculation."
U.S. Central Command earlier said that Iran had launched multiple ballistic missiles in what it described as an attempted surprise attack on U.S. forces based in the Middle East, and that those missiles were successfully intercepted. In a stated declaration, the Revolutionary Guards said that "as long as threats against the Islamic Republic of Iran continue and illegal and malicious actions by U.S. forces against our interests are under way, the resistance will also continue."
Diplomatic efforts and the Strait of Hormuz proposal
Against the backdrop of renewed military activity, Oman presented Iran with a proposal supported by Gulf states to jointly manage the Strait of Hormuz. The plan, as described by a Gulf source and a Western diplomat briefed on the matter, would establish a system for the waterway in which Iran would not have sole control and where contributions from ships would be voluntary. The concept was likened to arrangements in Asia's Strait of Malacca, where voluntary contributions help fund navigation, environmental protection and search-and-rescue services.
Gulf Cooperation Council foreign ministers convened via video call to discuss the latest developments, according to a statement from the Qatari Foreign Ministry. A U.S. official reiterated opposition to tolls or fees for ships passing through the strait, characterising the waterway as international and asserting it should be free from Iranian control or restrictions. The official said the deal under discussion would not include tolls or fees.
Historically, the strait has been a flashpoint: Iran effectively shut the passage after strikes on its territory on February 28. A subsequent agreement between the U.S. and Iran last month had partially reopened the strait and included plans for further talks on broader issues, including Iran's nuclear programme. That accord collapsed in early July after Iran fired on vessels using a shipping channel it does not recognise, compounding concerns about the reliability of maritime passage in the area.
Implications
The recent sequence of strikes and counterstrikes highlights both the fragility of the current ceasefires and the interdependence between military action and economic consequences. The targeting of facilities used to direct attacks on oil infrastructure, the reported engagement of commercial vessels in the strait, and the immediate response in energy markets together underline how security developments in the region can quickly feed into global supply and price dynamics.
At the same time, diplomatic initiatives such as the Omani proposal demonstrate a parallel push to manage the strategic chokepoint through cooperative frameworks. Whether such a plan can withstand the pressure of renewed hostilities remains unclear.
