Standing assessment
Current condition
Moderate confidenceAs of
A confirmed physical event with a disputed attribution.
Saudi Arabia attributed the March 2026 interception and terminal shutdown to Iran; Iran publicly denied targeting Gulf energy facilities, and Iranian messaging the same day was internally inconsistent — its defence ministry reported attacks on Qatari facilities and the Revolutionary Guard claimed a tanker strike. Vigil publishes the physical event and both positions and adjudicates neither.

Why it matters
Ras Tanura is the largest oil terminal in the world and the event halted it; who did it decides whether the Gulf's energy infrastructure was a deliberate Iranian target, a target of a faction inside the Iranian force structure, or something else. The internal inconsistency of the Iranian messaging is itself evidence in the command-authority question, which is why the two are connected. The change that counts is evidence from a party to neither account.

What would change the assessment2 thresholds · the boundaries as the record states them, none with a number
Evidence from a party to neither account that attributes the event
Would meanresolves the question and records the attribution on the event itself.
A Saudi revision or an Iranian acknowledgement
Would meanresolves it by admission rather than by evidence and is recorded as such.
What remains unknown
- No investigation report has been published by any party.
- The weapon type is reported inconsistently and is not stated here.
Readings the evidence also supports
- The event was a strike ordered by one part of the Iranian force structure without central authorisation, which is consistent with the inconsistent messaging and bears on the command-authority question.
Listed because the record's own assessment is not the only one its sources permit — not as a hedge on the assessment above.
