Iran Advances Hormuz Service-Fee Plan, Threatens Ship Seizures; Rezaei Vows 'Seismic' Retaliation Over Sanctions

Iran's parliament advanced legislation to impose service fees on vessels transiting the Strait of Hormuz, while officials warned that ships violating Iranian transit rules could face detention or confiscation. Supreme National Security Council secretary Mohsen Rezaei vowed 'seismic' retaliation against any country joining the US sanctions campaign — 'if [President Trump] wants to do something, we will retaliate in a seismic manner' — describing a three-stage strategy of negotiation, pressure, and ultimately strikes on non-compliant states' interests, and warning Iran would target oil tankers transiting the Omani side of the strait so that 'not even a single drop of oil will leave the region.' Despite the threats, shipping data showed roughly six vessels — three tankers and two cargo ships — transited the strait in the prior 24 hours, with Iran continuing to grant selective passage to Iraqi oil tankers.
