What happened in the Strait today

Iranian state broadcaster IRIB reported Thursday that several powerful explosions had rocked the southern passage of the Strait of Hormuz, citing military sources who said tankers using "unauthorized" routes may have struck naval mines deployed in the area, according to Al Jazeera's live coverage. The broadcaster offered no details on the number or identities of the vessels, casualties, or damage.

The explosions come as Tehran tightens its grip on the waterway. Iran has repeatedly warned vessels against using maritime routes not authorized by its authorities, and a senior regional official told Reuters this week that Iran's political leadership and Revolutionary Guards have agreed a plan to block routes not authorized by Tehran — including missile and drone attacks on ships and boats sent to scare them away. "This could involve missile and drone attacks on ships, or sending boats to scare ships away," a senior diplomat said. "It plans to continue this policy of fear and threats."

CENTCOM: "self-defense strikes" on mine-laying boats

In a significant confirmation, US Central Command acknowledged that American forces engaged Iranian forces in the Strait. "US forces conducted self-defense strikes in southern Iran today to protect our troops from threats posed by Iranian forces," a CENTCOM spokesperson told Fox News, adding that targets included missile launch sites and Iranian boats attempting to emplace mines, as reported by Maritime Executive.

A senior US official said on background that American forces destroyed two Iranian boats spotted laying mines in the Strait, along with a surface-to-air missile site in Bandar Abbas. Earlier, Iran's semi-official Fars news agency claimed Iranian forces had shot down a "hostile drone" over the Arabian Gulf, while Iranian social media accounts reported explosions near Bandar Abbas, Jask, and Sirik. Al Jazeera's Ali Hashem, citing an Iranian source, reported: "The IRGC targeted a vessel at sea, followed by U.S. fighter jets striking IRGC naval boats in the Gulf."

Markets react: oil jumps as transits plunge

Energy markets shuddered. Oil prices rose about 4 percent, with Brent settling at $104.28 a barrel and WTI at $91.49, amid renewed fears over the war and risks to shipping through the Strait, according to Al Jazeera. Gulf stock markets fell in early trade, with Saudi Arabia's benchmark index dropping 0.9 percent, Reuters reported.

Shipping data showed the number of vessels passing through the Strait fell to its lowest level in more than two months, after last week saw the highest number of tanker attacks of any week since the war began in late February. On Wednesday, projectiles struck a tanker 51 nautical miles north of Qatar, causing casualties, according to the UK Maritime Trade Operations agency.

Diplomacy under fire: ceasefire talks and Trump's midterm pledge

The violence unfolded even as sensitive negotiations between the US and Iran were believed to be closing in on a possible ceasefire extension. President Donald Trump said Washington was having "productive discussions" with Iran and pledged not to attack the country before the November 3 midterm elections. US Treasury Secretary Scott Bessent imposed fresh sanctions on 27 companies, six individuals, and 22 vessels, while Iran's Defence Ministry said weapons production had risen to 2.5 times its prewar level — enough, it claimed, for a "sustained and prolonged war."
