Unvalidated Claims: Responsibility for the tanker strike; Iran's future target set and claimed new capabilities.
Corrections: None identified.
Operational Significance: The rhetoric and confirmed maritime strike raise escalation, crew-safety and insurance risk even as diplomatic contacts remain possible.
Sources Checked: 3 directly opened reports; 2 supported validated developments.
Source Gaps: No directly opened full UKMTO notice or IRGC primary text; tanker identity and projectile attribution remain unavailable.
Recommended Follow-Up: Monitor UKMTO updates, vessel identification, U.S. and Iranian military statements, UN contacts and Hormuz traffic levels.
