Iran's Revolutionary Guard Navy says it carried out its largest single strike of the war on Saturday, hitting six vessels hours after US forces destroyed or disabled three Iranian tankers. In a statement carried by state broadcaster IRIB, the IRGC said it struck three oil tankers transiting what it called unauthorized routes through the Strait of Hormuz, plus three additional US-affiliated vessels "in other areas," and urged shipping in the Gulf not to be "deceived" by the US military's account [1].

Treat this as a claim, not a confirmed event. It reaches this feed through a single low-profile aggregator citing IRIB, with no independent maritime confirmation, no vessel names, and no damage assessment. CENTCOM's own account of Saturday's exchange says an aircraft carrier and a guided-missile destroyer "successfully evaded multiple unprovoked Iranian attacks" with no American personnel harmed, and it has not confirmed that any US Navy vessel was struck [1]. Iranian statements do not specify whether the three "US-affiliated" vessels were warships, US-flagged commercial ships, or something else. That gap between Tehran's claim and Washington's confirmed account is the story: both sides' claims have regularly outrun what the other verifies.

The US strikes that preceded it are already covered here: CENTCOM says it permanently disabled the M/T Downy off Kharg Island and the M/T Stark 1 near Jask and destroyed the unladen M/T Kylo in the Gulf of Oman, describing all three as part of a shadow network financing the IRGC [1].

The same report places the exchange in the wider war, saying Iran has effectively closed the strait to much commercial traffic since fighting began on 28 February, that the International Crisis Group counts at least 20 seafarers and a port worker killed, and that Brent peaked near $126 in early May before easing to the low-to-mid $90s [1]. Those are background figures from one outlet, not new corridor events.

What matters next is whether any of the six vessels can be independently identified.
