Eight Iranian tankers gone in four days, and Hormuz now runs at roughly one-eighth of normal traffic

The primary document is a US Central Command release: “U.S. Central Command (CENTCOM) forces destroyed five Iranian crude oil carriers, Sept. 8, after the Islamic Revolutionary Guard Corps (IRGC) targeted a U.S. Navy warship with ballistic missiles twice over the past two days.” Four of the vessels were in the Gulf of Oman and one near Kharg Island, Iran’s principal crude export terminal, according to CENTCOM’s account as reported by ABC News and CBS News; a ship identified as the M/T Riesco was filmed burning in video CENTCOM released and distributed through Reuters. CENTCOM says American forces “directed the crews to abandon ship before the vessels were struck and rendered inoperable,” and that no American personnel were harmed. Both claims are the US military’s own; no crew, owner or flag state has confirmed the evacuation warnings, and no casualty figure has been published by anyone. Three days earlier the command issued a near-identical release covering three Iranian crude carriers struck on 5 September after missiles were launched toward two US warships. That is eight hulls in four days on Washington’s account, and CENTCOM’s verb moved from “struck” to “destroyed” over the course of Tuesday.

Tehran’s answer, as carried by Iranian media and reported by Middle East Eye, was an IRGC statement claiming a ballistic missile attack on the US base at Al Azraq in Jordan in retaliation for the strikes on Iranian tankers. Middle East Eye noted there was no immediate confirmation from Jordan. Iran International, relaying Reuters, reported that all US troops in Jordan were accounted for; an unnamed US official told ABC News that “Iran’s response was ineffective in face of integrated air and missile defenses” and that “American forces have 100% accountability at all locations in Jordan.” No named official on either side has described damage. The more consequential line ran elsewhere: the Associated Press, via CBS News, reported that the IRGC Navy “warned crews of oil tankers near ports in Kuwait and Bahrain to immediately leave their vessels, saying the ships could be targeted in retaliation for the U.S. attacks on Iranian tankers.” The underlying Iranian text, any UKMTO or NAVTEX advisory, and any Kuwaiti or Bahraini response are all still missing. If it holds, it is the first threat in this cycle aimed at commercial tonnage sitting inside Gulf Arab ports rather than in transit.

The traffic data is where the accounts diverge furthest. Kpler figures cited by Al Jazeera on 8 September put transits at an average of ten commodity ships a day over the previous ten days, the lowest level since May; the same day, Qatar’s foreign ministry spokesperson said reopening the strait was a priority and warned of an “industrial catastrophe” if the crisis continued. Al Jazeera’s 3 September explainer, built on the same Kpler series, recorded six vessels on the Wednesday, eleven on the Tuesday and five on the Monday, for a ten-day average of thirteen — against President Trump’s claim that the United States was helping around thirty ships cross daily, and against Al Jazeera’s 7 September file headlined on Washington’s insistence that the waterway is “fully open.” A Fox News explainer puts normal throughput at roughly twenty million barrels a day and about a fifth of global liquefied natural gas; Trading Economics reported on 7 September that roughly seven million barrels a day of crude and products were still moving. Those two ratios do not match, and the mismatch is not yet explained by anyone publishing either number.

Assessment: The target set has changed, and that is the day’s finding. Strikes on IRGC military assets are a war; strikes on eight crude carriers in four days are an attack on the accounting that funds one, and Tehran’s reply — warning merchant crews at Kuwaiti and Bahraini berths — accepts that framing rather than rejecting it. Both sides now issue evacuation notices before threatening hulls, which is a courtesy that presumes more strikes. Distrust three things. CENTCOM’s assertion that no seafarers were harmed is unverified and comes from the party that fired; Iranian casualty and damage claims out of Jordan are equally self-reported and Jordan has confirmed nothing. And the volume figures do not reconcile: barrels are down roughly two-thirds while vessel counts are down closer to seven-eighths, which means either the seven-million-barrel figure is stale or cargo is being concentrated into fewer, larger, escorted hulls. Until IMF PortWatch or Kpler publish a reconciled series, “fully open” and “effectively closed” are both positions, not measurements.
