Iran temporarily shut part of the key Strait of Hormuz as tensions with the US continue to mount.
Tuesdayâs move is the first time the Middle Eastern waterway has been closed since the 1980s, and came as Iranâs ayatollah issued fresh threats against the United States.
One of the worldâs most strategically important routes, around 20 per cent of oil passes through the Strait of Hormuz between the Persian Gulf and the Gulf of Oman.
State media announced it would be partially shut for several hours due to âsecurity precautionsâ as the Revolutionary Guard carried out military drills.
Experts have previously warned that closing the Strait could cause a hike in oil prices if fuel is unable to get through.
International law permits countries to exercise control of up to 13.8 miles (12 nautical miles) from their coastline. At its narrowest point, the passage comes under both Iranian and Omani control.
The US and Iran held talks about a potential nuclear deal on Tuesday, with Tehranâs foreign minister announcing âguiding principalsâ had been agreed, without going into specifics.
Vice president JD Vance told Fox News: âIn some ways, it went well; they agreed to meet afterwards. But in other ways, it was very clear that the president has set some red lines that the Iranians are not yet willing to actually acknowledge and work through.â

Despite publicly committing to ongoing discussions on a deal, both sides have taken escalatory action in recent days.
The US positioned the worldâs largest warship, the USS Gerald R Ford, in the Middle East to join an earlier aircraft carrier, the USS Abraham Lincoln, that had moved to the region last month.
Ayatollah Ali Khamenei responded by threatening to sink the carriers.
âThe US president keeps saying, âour military is the strongest military in the worldâ; the worldâs most powerful military can sometimes receive such a slap that it can no longer stay on its feet,â he said on Tuesday. âThey constantly say, âwe have sent an aircraft carrier towards Iranâ.
âOK, of course an aircraft carrier is a dangerous device, but more dangerous than the carrier is the weapon that can send it to the bottom of the sea.â
Earlier in the week, Iran carried out military drills in the Strait, with missiles launched inside Iran and along its coast striking targets in the waterway.
The exercises, which included test missiles, warships and helicopters, were displaying the âoperational readinessâ of the Iranian Revolutionary Guard Corpsâ (IRGC) and plans for reciprocal action in case of âpotential security and military threatsâ.
On Wednesday, Iran and Russia announced joint navy drills in the Sea of Oman and the northern Indian Ocean would be carried out on Thursday.
âCreating convergence and coordination in joint measures to counter activities threatening maritime security and safety (…) as well as combating maritime terrorism, are among the main goals of this joint exercise,â Iranian navy commander Hassan Maghsoodloo said according to Fars News.
How the Iran war was years in the planning
On the sixth day of the US-Israeli war with Iran, the Strait of Hormuz is remains effectively closed to shipping, despite the US Navy crippling Iranâs surface fleet –Â including by torpedoing a Frigate off Sri Lanka.
On todayâs episode of Iran: the Latest, Roland Oliphant speaks to former Royal Navy commander Tom Sharpe about how Western militaries have prepared for years for a big war with Iran; why Iranian maritime forces are equally well prepared; and the cruel necessities of submarine warfare.
