The International Maritime Organization issued a new warning on November 11, 2026, calling for stronger enforcement of international maritime regulations in the Strait of Hormuz. Secretary-General Arsenio Dominguez cited more than 130 verified attacks on commercial shipping since the Middle East conflict began on February 28, with at least 25 seafarers killed and others missing or injured. He also raised concerns about substandard vessels, ships concealing their IMO identification numbers, fraudulent ship registrations and vessels operating under false flags. Dominguez called on flag, port and coastal States to address violations and urged shipping companies to refrain from commercial activities that expose seafarers to unacceptable risks. The IMO's incident register, updated through November 11, recorded 134 confirmed incidents across the Strait of Hormuz and wider Middle East region.
IMO Warns of a Second Threat in Hormuz: Ships With Hidden IDs and Questionable Flags
The Secretary-General's November 11 statement links a rising toll of attacks on commercial vessels with concerns over ships operating without fundamental safety compliance, reliable registration or visible identification.
Two Problems Highlighted in the Same Official Warning
The IMO reports more than 130 verified attacks since February 28, 2026, with at least 25 seafarers killed. The cumulative incident register includes cases in the Persian Gulf, Strait of Hormuz and Gulf of Oman region.
The Secretary-General specifically identifies obscured IMO numbers, fraudulent registration, false flags, substandard vessels and failures to observe fundamental SOLAS provisions.
Four Practices the IMO Has Identified
These are categories of concern reported by the Secretary-General, not findings against every ship transiting the strait.
Concealing permanent vessel identification impedes comparison of a ship's physical markings with its certificates and official records.
A vessel may claim a nationality without authorization from the flag State. A flag claimed by a ship is not proof of a valid registration.
The IMO warns of ships that do not comply with fundamental ship-safety obligations while operating in an already dangerous shipping corridor.
The Secretary-General calls on flag, port and relevant coastal States to exercise their responsibilities under applicable conventions and international law.
The Conflict's Escalating Official Toll
These are dated IMO updates. The latest figure is a regional incident total, while earlier milestones refer to attacks verified at the time.
The Secretary-General's Direct Appeal
Ten Named Ship Incidents Show the Threat. A Separate IMO Warning Targets Vessel Identity.
The IMO's verified incident list names affected vessels and documents damage, deaths and pollution reports. Its November 11 compliance warning raises broader concerns about fraudulent registration and concealed identification, without accusing the ships listed below of those practices.
Four Separate Legal and Verification Questions
A ship can have a valid IMO number but questionable registration, or valid registration but unresolved safety deficiencies. These are different checks governed by different rules and competent authorities.
For ships within the applicable SOLAS scope, the IMO identification number must be permanently marked in a visible position on the hull or superstructure and reflected in ship documentation. Its identity normally remains unchanged throughout the ship's life.
Ships must be registered under a flag they are authorized to fly. Under UNCLOS, States determine conditions for granting nationality and exercise jurisdiction over ships flying their flag. A claim on a certificate or AIS transmission is not conclusive proof of authorization.
The new guidelines address oversight of registries, ownership and identity checks, authorized registration processes and information exchange. They are guidance, not a newly created universal licensing treaty.
Port, flag and relevant coastal authorities must act within their jurisdiction and applicable international law. The November statement does not itself authorize every authority to detain a ship in any location.
Three Different Types of Vessel Identity Deception
A vessel continues claiming a flag even after registration with that State expires or is cancelled.
An organization falsely presents itself as entitled to register vessels on behalf of a national administration, sometimes using authentic-looking websites.
A ship transmits deliberately altered identification or the identity of another vessel. That is distinct from an ordinary AIS interruption, which requires context before conclusions are drawn.
Can the Vessel's Identity, Flag and Safety Records Be Independently Established?
Review documentary evidence behind a vessel's identity, claimed flag, physical markings and safety controls. Flag conflicting or missing items, export a follow-up register and distinguish an unverified record from a confirmed violation.
