Situation in Iran and Middle East Region

Security Update

Attacks against merchant shipping have continued in the Strait of Hormuz and wider Arabian Gulf. On 1 November, a tanker approximately 72 NM east of Ras Al Khafji, Saudi Arabia, was struck by two unknown projectiles, illustrating that the threat is not confined to vessels transiting the Strait. Recent incidents have also demonstrated a variety of attack methods, including the use of explosive devices attached to a vessel by a small craft. JMIC continues to assess the regional threat level as SEVERE. 

Commercial traffic through the Strait remains significantly below normal levels, contributing to large concentrations of vessels at anchorages and waiting areas across the region. In addition to the prevailing security threat, such congestion presents increased navigational and operational risks, particularly during anchoring, manoeuvring and when required to alter passage plans at short notice. Masters should remain alert to these additional risks and ensure appropriate bridge team and navigational precautions are maintained.  

GNSS and AIS interference also continues to affect the region. The reported incident picture may not be complete, with UKMTO noting that reporting is voluntary and that some incidents cannot be independently verified. Vessels are therefore encouraged to report incidents and suspicious activity promptly.

Members should continue to monitor UKMTO, JMIC and other recognised maritime security sources closely and ensure voyage-specific threat and risk assessments reflect both the security situation and the practical navigational risks arising from current traffic conditions.
