ISNA

ISNA, the Iranian Students News Agency, became a focal point of international scrutiny on 9 April 2026 when it co-published IRGC maritime charts showing a danger zone overlaid on the Traffic Separation Scheme lanes through the Strait of Hormuz. The charts were published jointly with Tasnim News Agency and directed commercial shipping away from the standard TSS corridors towards Larak Island channels under IRGC supervision. Their publication converted the formal Ceasefire reopening of the strait into a de facto IRGC toll system.

Founded in 1999 and nominally associated with Iran's student movement, ISNA has long operated as a semiofficial mouthpiece with close ties to IRGC media networks. It is not formally state-owned but regularly publishes operational military information that Western analysts treat as having official sanction. Its joint publication with Tasnim, which has explicit IRGC ties, reinforced the assessment that the Hormuz charts were an authorised IRGC communication rather than a leak.

ISNA's role in the Hormuz incident illustrated how Iran uses nominally civilian news agencies to convey operational military messages with plausible civilian framing. The publication of mine charts as a news story, rather than through official maritime channels such as a NOTAM, gave Tehran the ability to claim the information was public reporting rather than an official threat, while achieving the same strategic effect of intimidating tanker operators.
