A cargo vessel was struck by an unidentified projectile while transiting the Strait of Hormuz near the coast of Oman on Thursday, the UK Maritime Trade Operations (UKMTO) confirmed.

The incident marks a sharp escalation in maritime security risks, occurring simultaneously with a hardline directive from Iran’s Islamic Revolutionary Guard Corps (IRGC).

The IRGC stated that safe passage through the strategic chokepoint is now contingent on vessels using only routes designated by Tehran, warning of action against any ships that fail to comply.

The attack underscores the deteriorating security environment for commercial shipping in one of the world’s most critical energy corridors.

The Strait of Hormuz handles roughly a fifth of global oil consumption, and any disruption to transit flows has immediate implications for global energy markets.

The combination of physical attacks on vessels and the imposition of unilateral routing requirements by the IRGC creates a dual threat: direct physical risk to crews and assets, and operational complexity for shipping lines attempting to navigate the waters without violating Iranian demands.
