The Republic of the Marshall Islands Maritime Administrator has amended three ship security advisories SSA-01-24, SSA-02-24, and SSA-03-24 regarding threats to shipping.
The advisories were published on 15 May 2024.
SSA-01-24: Threats to Shipping in the Red Sea Region
Updates:
- The advisory has been revised to reflect significant developments in the Red Sea / Gulf of Aden region.
- The geographic scope now includes the Arabian Sea, the Eastern Mediterranean (EMED), and the Northwestern Indian Ocean.
- §2.0 has been updated with additional threat and risk considerations.
- Additional supplemental information has been provided in §8.0.
Threat and Risk Considerations:
- Regional actors in the Southern Red Sea (SRS), Bab-al-Mandeb (BaM), and Gulf of Aden (GoA) are capable of harassing and attacking commercial ships using various methods, including small boats, UAVs, and mines.
- Attacks continue in the SRS, BaM, and GoA, with potential risks extending to the Northern Red Sea, Arabian Sea, Northwestern Indian Ocean, and EMED. Vessels should remain vigilant.
- Houthis target ships linked to Israel, the US, and the UK, but all vessels risk collateral damage.
- On 3 May, Houthis threatened to target ships heading to Israel from the Mediterranean Sea, though air defenses are considered capable of countering this threat.
Supplemental Information:
- The Maritime Global Security website offers best practices, BMP guidelines, regional guidance, and security reporting contacts.
- Shipping industry associations have published interim transit advice for the SRS, BaM, and GoA.
- Latest security incident information and advice from coalition military forces are available on the UKMTO and MSCHOA websites.
