Iran Claims Seven Ships Hit in Strait of Hormuz, Warns US of Wider Response

Iran's IRGC claimed that seven vessels—four oil tankers and three ships that struck mines—were hit in the Strait of Hormuz on October 22, the largest single-day incident since February. The IRGC warned of potential strikes on US military bases if the US continues facilitating tanker transit, while the US dismissed the claims as electoral posturing. Despite ongoing attacks, oil continues flowing through the strategic waterway under US military protection, though at significantly elevated costs.

Oil tankers continue transit using 'dark shuttle' operations

Iran's Islamic Revolutionary Guard Corps (IRGC) reported on Thursday that seven vessels were struck in and near the Strait of Hormuz, marking the largest single-day toll since the US-Israeli military campaign against Iran began on February 28. According to IRGC statements, four oil tankers transferring cargo were targeted and caught fire overnight, while three additional vessels were disabled after striking naval mines. The IRGC said the targeted ships had crossed unauthorized routes and ignored warnings, with some vessels operating with radar and navigation systems disabled.

The incident comes as tensions escalate over control of the strategically vital waterway, through which roughly one-fifth of global oil supplies passed before the conflict. The IRGC warned that if the US military continues to assist tankers through the strait, "the confrontation could extend to its bases in the region," stating this as "a serious warning." Iran has asserted control over Hormuz since February 28, when it barred passage for vessels belonging to or affiliated with Israel and the United States following their joint strikes on Iranian territory.

The US has disputed Iran's claims. A US Central Command spokesperson told reporters that Iran's mine claims are incorrect, stating that US forces have cleared international shipping lanes of mines and that Iran uses missiles and drones instead. President Donald Trump said on Truth Social that "Iran is doing everything they can to drive up the price of oil prior to the US Midterm Election," adding: "They are making up fake hits, mines, and everything else."

Despite the attacks, oil tankers continue moving through the strait under US military escort. Operators have adopted a "dark shuttle" approach—transiting at night with communication systems disabled—to avoid detection, then transferring cargo to waiting vessels in the Gulf of Oman. This workaround maintains crude flows at roughly prewar levels, though at substantially higher costs: spot charter rates have soared to hundreds of thousands of dollars daily, and ship-to-ship transfers now take several days.

October has recorded 28 reported attacks on commercial shipping, the highest monthly toll since the war began in spring 2026. The escalation occurs amid concerns about a potential return to larger-scale military confrontation. Israeli Prime Minister Benjamin Netanyahu faces elections on October 27, while US midterm elections in early November approach; analysts warn that decisive electoral results could prompt renewed strikes on Iran. Iran's IRGC Army chief has stated that Iran is "more ready than anytime before" to wage symmetrical war against the United States.

Why This Matters

The Strait of Hormuz carries roughly one-fifth of global oil supplies; reported attacks on seven vessels on October 22 represent the largest single-day incident since February, driving up tanker charter rates to hundreds of thousands of dollars daily and forcing operators to adopt high-cost evasion tactics (night transits with disabled communications, delayed ship-to-ship transfers). October attacks total 28 reported incidents—the highest monthly count since the conflict began—creating elevated geopolitical and supply-chain risk ahead of Israeli (October 27) and US (early November) elections; Iran's IRGC has stated readiness for symmetrical conflict with the US.
