2025-06-11 12:00:00 CW Alert 012- (Jun 25) Indian Ocean Advisory Military UKMTO
It has been reported by the UKMTO that they are aware of increased tensions within the region which could lead to an escalation of military activity having a direct impact on mariners. Vessels are advised to transit the Arabian Gulf, Gulf of Oman and Straits of Hormuz with caution and are to report incidents or suspicious activity to UKMTO in accordance with BMP MS. UPDATE: The UKMTO has issued an update from the Joint Maritime Information Centre (JMIC) citing open-source media reports that Israeli authorities forwarded an ultimatum to both Iran and the United States, stating that a nuclear agreement must be reached by Sunday between the two countries. If not, Israeli leadership has an intent to initiate military action against Iran. The statement introduces a short operational pause until Sunday to allow diplomatic efforts. Currently, there is no direct evidence that commercial shipping is being targeted. However, given the proximity of regional flashpoints to major maritime routes and chokepoints, the potential for rapid escalation involving the maritime environment should not be discounted. The JMIC will monitor the situation closely and provide timely updates accordingly should there be any changes.
