Iran’s Islamic Revolutionary Guard Corps (IRGC) navy said on social media on the
25th that vessels transiting the Strait of Hormuz must coordinate with the IRGC
navy and that non‑compliant ships “will be dealt with.” It said some agencies
hours earlier had announced new transit routes without Iranian coordination,
calling those routes unacceptable and extremely dangerous. The IRGC navy warned
transit is permitted only via Iran‑published routes and that navigation outside
those routes are prohibited and extremely dangerous.
