The social media post attempted to connect the purported attack to Donald Trump’s statements regarding a potential agreement over the Strait of Hormuz.
WASHINGTON, DC: A rumor spread rapidly online claiming that Iran’s Islamic Revolutionary Guard Corps (IRGC) fired an anti-ship cruise missile toward a US-associated oil tanker after the vessel reportedly disabled its Automatic Identification System (AIS).
This report sparked widespread concern over a potential escalation in one of the planet’s most vital maritime trade lanes. Here is a closer examination of the facts behind the allegation.
The Allegation: IRGC fires cruise missile from Sirik toward the Strait of Hormuz
BREAKING: Iran’s IRGC has just launched an anti-ship cruise missile from Sirik toward the Strait of Hormuz per initial reports, with the likely target being an oil tanker sent by the US that switched off its AIS an hour ago while passing through the US-backed southern route.…

An X (formerly Twitter) account known as “The Hormuz Letter” published a post asserting that the IRGC launched a missile from the Iranian coastal city of Sirik.
According to the post, the projectile was aimed at a tanker linked to the United States that had gone “dark” by turning off its tracking transponder while navigating the southern corridor near Oman.
The online commentary framed the alleged strike in the context of recent comments by Donald Trump concerning potential negotiations over the Strait of Hormuz and upcoming diplomatic talks with Tehran.
The post sought to portray the event as a sign that Iran was forcibly challenging international shipping norms in a critical energy transit route, despite ongoing diplomatic channels.
The original post read: “Iran’s IRGC has just launched an anti-ship cruise missile from Sirik toward the Strait of Hormuz per initial reports, with the likely target being an oil tanker sent by the US that switched off its AIS an hour ago while passing through the US-backed southern route.”
It additionally noted: “This comes as Trump simultaneously claims just minutes ago ‘there’s a deal on Hormuz and there will be a deal on denuclearization’ with ‘new Iran negotiations to begin Monday afternoon.'”
Verification: Unverified and Lacking Credible Support
At present, the claim remains entirely unverified. No authoritative sources have produced evidence indicating that an Iranian missile was fired at a US-connected vessel near Sirik.
Key monitoring authorities—including the UK Maritime Trade Operations (UKMTO), the US Department of Defense, regional governments, and international news agencies—have issued no confirmations regarding a missile launch, an explosion, or a targeted American tanker.
All specific details regarding the launch site, the disabled transponder, and the targeted vessel originate exclusively from unverified social media profiles, primarily the account that broke the story. None of these assertions have been independently corroborated.
While geopolitical tensions in the Strait of Hormuz are genuinely elevated, and the IRGC has a history of maritime harassment and vessel seizures in the area, past friction does not validate this specific, unproven event.
Similarly, although Donald Trump did mention prospective talks and a potential agreement concerning Hormuz around the same timeframe, there is no verified link between his remarks and the alleged attack. Until official maritime or government agencies corroborate the story, the report should be viewed with skepticism.
