The Strait of Hormuz has once again become the centre of a dangerous confrontation between the United States and Iran after American forces struck two rocket launchers on Iran’s Larak Island, prompting Tehran to retaliate against US-linked military positions in the region.
The exchange of fire marks the first known US strike on Iranian territory since Washington paused a renewed military campaign against Tehran in late July.
And with the confrontation taking place at one of the world’s most strategically important waterways, the latest escalation is about far more than missiles and military bases.
It could have consequences for global energy supplies, shipping and already volatile oil markets.
How the latest confrontation began
The US military said its forces carried out what it described as a “limited, precise action” against two rocket launchers on Larak Island after detecting preparations by Iranian forces to launch rockets and deploy sea mines in the Strait of Hormuz.
The American assessment was that the activity posed an immediate threat to shipping and US interests in the region.
US Central Command (Centcom) said it acted after observing preparations that could potentially disrupt maritime traffic through the strategic waterway.
Iran, however, described the attack as American aggression.
The Islamic Revolutionary Guard Corps (IRGC) said the strikes killed two people and injured two others, while warning that the US action would not go unanswered.
The incident represents a significant escalation because Larak Island is positioned directly inside the Strait of Hormuz, close to Iran’s major port city of Bandar Abbas.
Tehran strikes back
Iran’s response came hours later.
Iranian state media reported that the IRGC launched ballistic missiles at US military facilities in Jordan, identifying the King Hussein and al-Azraq bases as targets.
Jordan subsequently said its forces intercepted eight missiles early Monday.
Iran’s Foreign Ministry defended the attacks as a legitimate act of self-defence following the US strike on Larak Island.
President Masoud Pezeshkian also sought to frame Tehran’s position as retaliatory rather than expansionist.
“We are not seeking war, but we will deliver a decisive response to the aggressors,” he said, according to AFP.
Iranian state television separately reported that the Iranian military had targeted an air base in the United Arab Emirates with drones.
The UAE, however, rejected the claim that Al-Minhad Air Base had been targeted, describing the report as unfounded.
Abu Dhabi did confirm that its forces had intercepted a drone.
The conflicting accounts underline the fog surrounding the latest confrontation, with competing claims emerging from the countries involved as the situation develops.
Why Larak Island matters
The location of the US strike is particularly significant.
Larak Island sits just off Iran’s southern coast and close to Bandar Abbas, while the Strait of Hormuz separates Iran from the Gulf states.
At its narrowest point, the waterway is only about 21 miles (33 kilometres) wide.
Yet this narrow corridor carries enormous strategic importance.
Before the current conflict disrupted maritime traffic, roughly one-fifth of the world’s oil and liquefied natural gas supplies passed through the Strait of Hormuz.
That makes any threat to the waterway capable of sending shockwaves far beyond the Middle East.
A missile exchange around Larak Island, therefore, is not simply another episode in the US-Iran confrontation.
It is happening beside one of the arteries of the global economy.
The strait has already been caught in the conflict
Since the conflict began in February, shipping through the Strait of Hormuz has effectively been shut down, contributing to sharp swings in international oil prices.
Iran has demanded that tanker traffic passing near Larak Island undergo checks and has reportedly required vessels to pay as much as $2 million to cross.
Tehran has also been accused of attacking or threatening vessels that attempt to navigate the waterway without its permission.
Iran maintains that its actions are connected to the conflict and its efforts to control the strategically important route.
The United States, meanwhile, has been conducting a naval blockade against Iran.
Centcom said on Saturday that American forces had disabled three vessels, boarded two others and redirected 82 as part of the operation.
The confrontation has therefore moved beyond conventional airstrikes.
The sea itself has become part of the battlefield.
Trump raises the temperature
US President Donald Trump also appeared to escalate the rhetoric following the latest strikes.
Hours after the attack, Trump posted apparent AI-generated videos on Truth Social showing oil infrastructure exploding.
One post was captioned, “Kharg Island being blown to smithereens!!!”
Kharg Island is home to a major Iranian oil terminal and has previously been threatened by Trump.
The post did not provide further details about what action, if any, Washington intended to take against the facility.
The reference nevertheless carries weight because an attack on Iran’s oil infrastructure could dramatically widen the economic and military consequences of the conflict.
Washington and Tehran disagree over the mines
The Strait of Hormuz has become particularly sensitive because of the threat posed by naval mines.
Trump said last week that mines allegedly deployed by Iran as part of its attempt to blockade the waterway had either been detonated or removed.
He also warned that any ship or boat attempting to lay new mines would be destroyed.
Iran rejected the claim.
Deputy Foreign Minister Kazem Gharibabadi dismissed Trump’s statement as propaganda, reflecting the wider dispute between Washington and Tehran over control of the waterway.
The latest US strike suggests that Washington remains deeply concerned about the possibility of Iran restricting maritime traffic through the strait.
A conflict with global consequences
The latest escalation comes against the backdrop of increasing economic pressure on Tehran.
The United States announced a fresh sanctions campaign on August 24 aimed at further isolating Iran and expanding secondary sanctions against countries and entities that maintain ties with the Iranian economy.

Iranian officials and state media have largely dismissed the measures as another version of Washington’s existing pressure campaign.
Tehran has argued that the sanctions follow what it describes as a failed US military effort in the recent conflict.
But while the two governments trade accusations and threats, the economic consequences are being felt far beyond Washington and Tehran.
Oil markets remain vulnerable to disruption.
Shipping companies face heightened risks.
And governments dependent on Middle Eastern energy supplies must once again consider what happens if the Strait of Hormuz remains effectively closed or becomes an active military theatre.
The bigger question
The immediate question is no longer simply whether the US and Iran will exchange more strikes.
It is whether the confrontation can remain contained.
The United States has already demonstrated its willingness to strike Iranian military assets around the Strait of Hormuz. Iran has responded by targeting US-linked positions elsewhere in the region.
The possibility of further escalation now hangs over a waterway through which a huge share of global energy supplies once moved freely.
For Washington, keeping the strait open is a strategic priority.
For Tehran, control of the waterway offers one of its most powerful tools for exerting pressure on the United States and its allies.
That makes the Strait of Hormuz more than a narrow strip of water.
It is now a pressure point where military calculations, energy security and global economics collide.
And every missile, drone or naval mine introduced into that equation risks turning a regional confrontation into a crisis the rest of the world cannot afford to ignore.
