Situation in Iran and Middle East Region

Security Update

The security situation in the Arabian Gulf, Strait of Hormuz and Gulf of Oman remains highly volatile, with an increase in reported attacks against commercial shipping. While tankers continue to be targeted, recent incidents have also affected container vessels and other vessel types, with at least four container vessels reportedly struck between 11 and 14 October. One container vessel subsequently sank following an attack.  

Recent incidents have also extended beyond the Strait of Hormuz. Reported attacks have occurred in the central Arabian Gulf and against a tanker at anchor off Sohar, Oman, whilst a tug was recently struck during an outbound Strait of Hormuz transit. The pattern of incidents suggests that elevated risks are no longer confined to the principal transit corridor and may affect both transiting and stationary vessels operating elsewhere in the region.  

Reporting has also referenced possible naval mine incidents and mine activity, although these reports remain uncorroborated and should be treated with caution pending independent verification. 

The Joint Maritime Information Centre (JMIC) continues to assess the threat to merchant shipping in the Strait of Hormuz as SEVERE, with deliberate hostile action considered highly likely. Continued reports of projectile attacks, UAV activity, suspicious VHF communications, GNSS interference and heightened military activity underline the need for vigilance.  

Members operating in the region should undertake voyage-specific risk assessments, seek appropriate security advice, maintain liaison with UKMTO and relevant naval authorities, and monitor official reporting closely. Particular consideration should be given to the potential for rapidly changing security conditions, attacks affecting both transiting and stationary vessels, and the risks posed by navigation interference and possible mine activity.
