India’s maritime regulator, the Directorate General of Maritime Administration (DGMA), issues an advisory directing ship owners, ship managers and recruitment and placement firms not to deploy Indian seafarers on vessels transiting the Strait of Hormuz until further orders. The DGMA cites heightened security risks in the Persian Gulf amid renewed tensions between the United States and Iran and says the advisory is meant to protect the safety, security and welfare of Indian seafarers. The directive is accompanied by instructions for vessel masters to maintain heightened vigilance in the Strait of Hormuz and nearby waters, continuously monitor navigational warnings and security advisories, and strictly implement security measures under the International Ship and Port Facility Security (ISPS) Code. The advisory follows attacks on merchant vessels in the region reported across several sources, including ships such as MT Mombasa and MT Al Bahiyah, as well as MV GFS Galaxy and other named vessels. Some reporting says Indian nationals are killed or reported missing in separate incidents involving vessels in the Strait of Hormuz and off Oman. India also carries out diplomatic steps, including summoning an Iranian diplomatic official to protest the attacks, according to one report.
