Seven oil tankers caught fire or were damaged overnight in and near the Strait of Hormuz, Iranian state television reported on Thursday, October 22 — a markedly high single-day toll that has stoked fears of a return to all-out war in the region. Citing the navy of Iran's Islamic Revolutionary Guard Corps, the broadcaster said four tankers were struck while transferring oil and three others hit naval mines. The claims could not be independently verified, and a British maritime security monitor had not reported the incidents.
What Iran claims happened
According to the IRGC Navy statement carried by Iranian state TV, its forces tracked four tankers engaged in what Tehran called "illegal oil transfers" in the northern Persian Gulf on Wednesday, then hit them with projectiles; all four caught fire. Separately, three other tankers struck naval mines west of the Strait of Hormuz and were left disabled, unable to continue moving, according to the IRGC statement carried by Al Jazeera.
The report did not identify the seven vessels, did not say which flags they flew, and did not mention any casualties. The United Kingdom Maritime Trade Operations, a British maritime security monitor, had not reported the incidents — though monitors have noted in recent days that some shipping operators appear reluctant to report attacks, the Associated Press reported.
A direct warning to US bases
The IRGC used the announcement to threaten American military assets in the region, accusing the US Navy of guiding commercial ships through routes Tehran considers unauthorized. "The US military must know that if this trend continues, the conflict will extend to its bases in the region. This is a serious warning," the IRGC Navy statement said.
Iranian Foreign Minister Abbas Araghchi said on Wednesday that Tehran remains open to diplomacy but is ready to defend itself. Tehran has also indicated it could broaden its targets to infrastructure such as undersea cables and data centers, the AP reported. The attacks come after US President Donald Trump rejected Tehran's proposal to end the war and fully reopen Hormuz within a week, conditioned on ending the US blockade of Iranian ports, according to the AP.
Oil prices jump; US pushes back
Brent crude rose about 3% to $112 a barrel on October 22 — a five-month high — as markets absorbed the Hormuz claims alongside Houthi strikes on Saudi targets, the Guardian reported. On the same day, Iran-aligned Houthis hit Saudi Arabia's King Fahd airport in Dammam, killing 2 people and wounding 8, and struck Aramco's Shaybah oilfield, killing 2 more, Reuters reported.
Trump dismissed the tanker claims on Truth Social, saying Iran is "making up fake hits, mines, and everything else" to drive up oil prices ahead of next month's US midterm elections. An anonymous US CENTCOM spokesperson told Al Jazeera the mine claims were incorrect, said US forces had cleared international shipping lanes of mines, and claimed the strait remains open with 95% of vessels getting through — describing the attacks as a sign of Tehran's "desperation" under the US blockade.
The United States is sending more military assets to the region, including a third aircraft carrier and thousands of troops, to join what the AP described as the largest force of American warships and aircraft in the Middle East in decades. The US also ordered non-emergency personnel and families out of missions in Saudi Arabia after the Houthi strikes, Reuters reported.
Why it matters
The Strait of Hormuz carries a huge share of the world's seaborne oil, and the war that began with US and Israeli strikes on Iran on February 28 has already made it the most dangerous shipping lane on Earth. Whether or not Tehran's claims about the seven tankers hold up, the pattern is unmistakable: attacks are escalating, oil markets are rattled, and both sides are openly preparing for the possibility that this war is about to get bigger. With Israel's election days away and US midterms next month, the coming weeks could decide whether Hormuz stays a pressure point — or becomes a flashpoint.
