What Happened

The United Nations Secretary-General, through a spokesperson, formally condemned the attack on the oil tanker MT Settebello that resulted in the deaths of three Indian seafarers off the coast of Oman near the Strait of Hormuz.
The UN Secretary-General's statement underscored that "the exercise of navigational rights and freedoms, in accordance with international law, must be respected," reinforcing the principle of freedom of navigation under UNCLOS.
The International Maritime Organization (IMO) Secretary-General separately issued a strong condemnation, expressing "deep sadness" and calling the attacks "simply unacceptable," stating that "any act from any party that endangers the lives of seafarers and the safety of international shipping" is to be condemned.
MT Settebello, a Palau-flagged tanker, was struck during US blockade enforcement operations in the Strait of Hormuz on June 10; three Indian sailors were killed and 21 Indians were rescued by Omani authorities.
As of early June 2026, the wider Strait of Hormuz crisis had resulted in 46 verified attacks on international shipping and 14 confirmed seafarer fatalities since the crisis began on 28 February 2026.

International Maritime Organization (IMO) — Mandate, Composition, and Powers

The International Maritime Organization (IMO) is a specialised agency of the United Nations responsible for the safety, security, and environmental performance of international shipping. Established by a convention adopted in 1948 (entered into force 1958), the IMO is headquartered in London. It has 175 member states and 3 associate members. The IMO develops and maintains the global regulatory framework for shipping, including the key maritime safety conventions.

IMO Secretary-General: Arsenio Dominguez (elected 2023, first from Latin America — Panama).
Key IMO conventions: SOLAS (Safety of Life at Sea, 1974), MARPOL (prevention of marine pollution), STCW (Standards of Training, Certification and Watchkeeping for Seafarers), MLC (Maritime Labour Convention, 2006).
SOLAS 1974 is the most important IMO safety convention; it sets minimum construction, equipment, and operational safety standards for merchant ships.
The IMO's remit is regulatory and recommendatory — it does not have enforcement powers. Enforcement rests with flag states (the country under whose flag a ship is registered) and port states.
The Maritime Labour Convention (MLC, 2006), developed jointly with the ILO, is sometimes called the "seafarers' bill of rights."

Connection to this news: The IMO's condemnation represents the formal voice of the global maritime regulatory body; however, its lack of enforcement powers means that the condemnation is a diplomatic and moral statement rather than a legally binding remedy.

Flag State Jurisdiction and the Law of the Sea

Under international law, every merchant ship must be registered under the flag of a particular state, giving that state jurisdiction and responsibility over the vessel. MT Settebello was registered under the flag of Palau; MT Marivex was also Palau-flagged; MT Jalveer was Guinea-Bissau-flagged. Flag states are responsible for ensuring their vessels comply with international maritime law. On the high seas and in international straits, flag state jurisdiction is primary — other states do not have the right to stop or attack a vessel unless specific conditions are met (e.g., piracy under UNCLOS Article 105, or UN Security Council-authorised enforcement).

UNCLOS Article 91: Every state shall fix the conditions for the grant of its nationality to ships. Ships have the nationality of the state whose flag they are entitled to fly.
UNCLOS Article 94: Flag states must exercise effective jurisdiction and control in administrative, technical, and social matters over ships flying their flag.
"Flag of convenience" (FOC) refers to the practice of registering ships in states with minimal regulatory oversight and lower costs — Palau and Guinea-Bissau are FOC registries.
Article 105 of UNCLOS is the only provision permitting seizure of a foreign vessel on the high seas (for piracy); there is no UNCLOS provision permitting military strikes on civilian merchant vessels as "blockade enforcement" without UN Security Council authorisation.

Connection to this news: The attacks on Palau-flagged and Guinea-Bissau-flagged vessels carrying Indian crews raise complex questions of flag state jurisdiction, international humanitarian law at sea, and the absence of a UN Security Council mandate for the US blockade enforcement operations that targeted these commercial vessels.

UNCLOS and the Protection of Seafarers in Armed Conflict

UNCLOS (1982) governs peacetime maritime rights but its provisions intersect with the laws of armed conflict (international humanitarian law, or IHL) when military operations affect civilian shipping. The San Remo Manual on International Law Applicable to Armed Conflicts at Sea (1994) — while not a binding treaty — is the most authoritative codification of how IHL applies at sea. It provides that merchant vessels may only be attacked if they satisfy specific criteria establishing that they are contributing to the enemy's war effort.

The San Remo Manual (1994) is a product of international experts convened by the International Institute of Humanitarian Law; though non-binding, it reflects customary IHL at sea.
San Remo Manual Rule 67: Merchant vessels may be subject to capture if they are, among other conditions, carrying contraband or acting in breach of a lawful blockade.
"Lawful blockade" under the San Remo Manual requires, inter alia: declaration and notification to all states, effectiveness, non-starvation of the civilian population, and proportionality.
Civilian seafarers are protected persons under the four Geneva Conventions (1949) and their Additional Protocols (1977).
The UN Secretary-General's statement explicitly referenced "navigational rights and freedoms, in accordance with international law" — framing the issue within the international legal framework rather than as a political dispute.

Connection to this news: The deaths of three Indian seafarers and the endangerment of dozens more on unarmed commercial tankers raise questions about the application of IHL at sea, including whether the blockade enforcement operations targeting these vessels met the legal standards for a lawful blockade.

India's Seafaring Workforce — Scale and Diplomatic Significance

India is one of the world's top five suppliers of seafarers, with approximately 1.7 lakh (170,000) Indian nationals working in the global merchant marine at any given time. Indian seafarers are employed on vessels of all flags and in all major shipping lanes, including the Persian Gulf, the Red Sea, and the Strait of Hormuz — making conflict in these waterways a matter of direct national interest for India.

India ranks among the top five seafarer-supplying nations globally (alongside Philippines, China, Indonesia, and Russia).
The Directorate General of Shipping (DGS), under the Ministry of Ports, Shipping and Waterways, regulates Indian seafarers and their certifications.
Indian seafarers are covered by the Maritime Labour Convention (MLC, 2006) standards when employed on ships from signatory states.
India has bilateral Labour Mobility Agreements with several Gulf states for seafarers and other migrant workers.
Remittances from Indian seafarers contribute meaningfully to overall remittance inflows.

Connection to this news: The disproportionate impact of the Hormuz crisis on Indian seafarers — given India's status as a major seafarer-supplying nation and the geographic concentration of Indian maritime workers in Gulf-transiting vessels — has elevated the condemnation of these attacks to a matter of bilateral and multilateral diplomatic engagement.
