The reported strike on the Tanzania-flagged cargo ship Tihamah off Yemen’s southern coast has renewed attention on the civilian cost of maritime conflict. This was not simply another shipping-security incident or a disruption to commercial supply chains. It showed how seafarers, who are civilian workers operating merchant vessels, are increasingly being placed in the path of armed conflict across some of the world’s most important waterways. The United Nation response has placed this human reality at the centre of the crisis: global trade matters, but the lives of the people who keep that trade moving must matter more.
UN News reported that several seafarers were believed to have been killed in the attack, which was attributed by Yemeni officials and some maritime-security sources to Yemen’s Houthi movement. Online marine registries listed the Tihamah as a 62.8-metre-long and 11-metre-wide deck cargo vessel sailing under Tanzania’s flag. Yet the initial account did not establish several key details, including the identity of the shipowner, the type of cargo, the weapon used, the precise location of the attack, the nationalities of the crew, the confirmed number of fatalities or the final condition of the vessel.
These gaps are important. Incidents in active conflict zones are often followed by competing claims from political authorities, military actors and security agencies. A credible Analysis must distinguish between confirmed facts, official allegations and preliminary maritime reports. The absence of full information does not reduce the seriousness of the attack. Instead, it makes transparent verification even more necessary, particularly when civilian deaths may have occurred.
Other reports stated that four crew members and two rescuers were killed, while Yemeni authorities reported that additional people were injured during rescue operations. Maritime-security accounts described an unidentified projectile striking the vessel near Yemen’s Perim Island, close to the Bab al-Mandab corridor. At the time, the Houthis had not publicly claimed responsibility, even though Yemen’s internationally recognised government accused them of carrying out the attack and held them responsible for the casualties and damage. This uncertainty underlines why attribution should rest on independently assessed evidence rather than on immediate political narratives.
Civilian Crews Cannot Be Expendable
The crisis surrounding the Tihamah demonstrates a widening danger for merchant crews navigating the Red Sea, Gulf of Aden and nearby waters. Commercial ships may carry food, fuel, industrial materials, consumer goods and humanitarian supplies, but they are staffed by civilians who are neither military personnel nor participants in regional conflicts. They often have no control over routing decisions, security procedures, port calls or whether a vessel enters waters that have become militarised.
The maritime warning from the United Nation system has been explicit. Arsenio Dominguez, IMO Secretary-General:
“It is with sadness and regret to know that, once again, innocent seafarers have lost their lives in an indefensible attack on international shipping.”
His words frame the issue as more than a commercial or logistical problem. They highlight the basic legal and moral distinction between civilian labour and armed conflict.
Seafarers already work under difficult conditions. They spend extended periods away from their families, operate within multinational crews, manage heavy cargoes and navigate hazardous weather, mechanical risks and tight schedules. When major sea lanes become conflict zones, these existing pressures are compounded by the risk of missile strikes, drones, mines, boarding attempts, detention and sudden rerouting. Civilian crews can become trapped between the strategic goals of armed groups and the commercial calculations of shipping companies.
The wider humanitarian perspective was captured by the UN Secretary-General. António Guterres, UN Secretary-General:
“Behind the cargo figures and the price surges are people.”
He also stressed that seafarers “are not parties to any conflict” and that their safety, well-being and rights must be protected across all waters. That intervention is significant because public debate about maritime insecurity often focuses on container rates, oil prices, insurance costs and naval operations rather than the people who face the immediate danger.
The United Nation Red Sea attacks debate must therefore avoid treating crews as an afterthought. When ships are attacked, delayed or diverted, seafarers are not simply part of a broader supply-chain statistic. They are individuals facing fear, trauma, injury, detention or death while working in a conflict environment they did not create.
Two Chokepoints Under Intense Pressure
The Tihamah incident is particularly consequential because it occurred close to Bab al-Mandab, the narrow maritime passage that links the Red Sea with the Gulf of Aden. This route is a vital southern gateway to the Suez Canal corridor, connecting trade flows between Asia, Europe, Africa and the Mediterranean. Any sustained insecurity in this area affects not only regional commerce but also global shipping schedules, freight costs and access to essential goods.
When shipping companies avoid Bab al-Mandab and the Red Sea, many vessels are forced to travel around Africa’s Cape of Good Hope. This longer route adds days or weeks to voyages, increases fuel consumption and exposes crews to longer deployments at sea. It can also raise insurance costs, intensify pressure on ship schedules and increase the cost of goods delivered to ports across Europe, Asia and Africa.
The Red Sea crisis is also linked to growing insecurity in the Strait of Hormuz, creating a dangerous two-chokepoint problem in the Middle East. Bab al-Mandab controls access between the Indian Ocean and the Red Sea, while Hormuz is essential for the movement of Gulf energy exports and other commodities. A threat to either route can create economic disruption. Pressure on both at the same time can produce a far more serious international shock.
The United Nation report said only around seven vessels crossed the Strait of Hormuz on one Sunday, almost 20 times lower than the usual pre-war daily average. The International Maritime Organization also indicated that approximately 6,000 seafarers and 500 vessels remained trapped in or near Hormuz, while around 2,900 people had been evacuated. Since early March, the IMO crisis tracker had recorded 65 incidents and 17 seafarer deaths associated with the Hormuz emergency.
These figures reveal the scale of the danger. The issue is no longer confined to isolated attacks against individual ships. It has become a wider disruption affecting the movement of people, vessels, energy supplies and commercial cargo across multiple waterways. In an interconnected global economy, simultaneous instability in Bab al-Mandab and Hormuz affects countries far beyond the Middle East.
António Guterres, UN Secretary-General:
“Safe, unimpeded passage is an economic and humanitarian imperative.” T
he phrase “humanitarian imperative” is particularly relevant. These trade routes carry fuel, food, medicines, industrial inputs and basic consumer goods. Prolonged disruption can drive up costs and delay supplies, with import-dependent countries and low-income households often suffering the greatest consequences.
Maritime Coercion and Legal Responsibility
The Houthis, also known as Ansar Allah, have linked their maritime campaign to support for Palestinians in Gaza. Since the Gaza war began in October 2023, the group has threatened or targeted commercial shipping in and around the Red Sea and has signalled an intention to use Bab al-Mandab as a point of political and military pressure. By threatening a narrow international waterway, the group has shown how a regional armed movement can create consequences for global trade and maritime security.
In late July, the Houthis reportedly claimed attacks on two Saudi oil tankers. Following those reported strikes, the United Nation Secretary-General expressed deep concern about renewed attacks against commercial vessels and new threats to freedom of navigation. The growing concern is that once merchant shipping becomes a tool for coercion, the risks quickly extend beyond any originally defined target group.
The Tihamah case also shows the limits of relying on initial claims from any side. Yemen’s recognised government blamed the Houthis for the attack, while the Houthis had not publicly claimed responsibility at the time of reporting. Maritime-security sources referred to an unidentified projectile. These differences do not justify indifference to civilian casualties. They demonstrate why independent fact-finding and clear public reporting are vital after every incident.
The legal principle, however, remains clear regardless of the attacker’s identity. Arsenio Dominguez, IMO Secretary-General:
“The safety of seafarers is a fundamental obligation under international law.”
This obligation requires armed actors to avoid attacks on civilian ships and crews. It also requires states and relevant authorities to take reasonable measures to protect navigation, support search-and-rescue missions, facilitate evacuations and reduce foreseeable risks to civilian personnel.
Responsibility cannot be viewed only through the narrow question of who fires a weapon. Flag states, coastal authorities, vessel owners, shipping companies, insurers and governments with naval capabilities all influence the level of protection available to crews. Commercial decision-making must not place delivery schedules, freight revenue or insurance calculations above the safety and informed welfare of people on board.
The Economic Cost Has a Human Face
The economic impact of maritime violence is significant, but it must not overshadow the human toll. Earlier disruptions in the Red Sea forced more than 60 percent of container shipping to reroute around the Cape of Good Hope. War-risk insurance premiums reportedly rose from around 0.05 percent to more than 1 percent of a ship’s insured value. For a large tanker, that increase can approach $1 million per voyage.
Historical data also illustrates how quickly a regional crisis can alter global shipping patterns. The International Monetary Fund recorded Bab al-Mandab passages at 46 percent of their previous-year level in January 2024, while traffic around the Cape of Good Hope increased by 70 percent. During the same period, the average cost of shipping a 40-foot container increased from $1,521 on 14 December 2023 to $3,777 on 18 January 2024.
These figures are not direct measurements of the Tihamah incident, but they demonstrate how insecurity in the Red Sea can produce global inflationary pressure. Higher transport and insurance costs affect manufacturers, importers, retailers and consumers. Delays can disrupt production systems dependent on timely deliveries of components and raw materials. For countries dependent on imported fuel, food or medicines, the consequences can become social and humanitarian rather than merely commercial.
United Nation trade officials have warned that continued Red Sea disruption could increase delivery times, transport costs and inflationary risks. Jan Hoffmann, UNCTAD trade official:
“We are very concerned that the attacks on Red Sea shipping are adding tensions and costs to global trade.”
He also warned that a prolonged container-shipping disruption could destabilise supply chains in a manner comparable to pressures seen during the COVID-19 period.
However, rerouting ships does not eliminate human risk; it redistributes it. Longer voyages mean more time away from home, greater crew fatigue, heavier workloads and exposure to hazards across alternative routes. The problem cannot be solved solely by shifting vessels away from Bab al-Mandab. The deeper requirement is to reduce the threat to civilian shipping and protect the people operating these vessels.
A Test for United Nation Action
The United Nation has articulated a strong legal and humanitarian position, but its practical ability to enforce safety in an active conflict zone remains limited. It can convene states, document attacks, support international law, coordinate maritime agencies, facilitate evacuation efforts and press parties to protect civilian lives. It cannot independently guarantee that a merchant vessel will not be attacked.
This gap between legal principles and operational realities is at the heart of the current crisis. The IMO has called for the immediate and unconditional release of seafarers detained after piracy incidents in the Red Sea and Gulf of Aden. It has also developed an emergency evacuation framework intended to assist crews and vessels trapped by the Hormuz crisis. Such measures recognise that civilian protection cannot wait for the resolution of wider geopolitical disputes.
The United Nation must continue to oppose the normalisation of attacks on commercial shipping. That requires credible investigation of incidents, transparent reporting of verified findings, sustained diplomatic engagement, effective rescue arrangements and stronger protection for crews in high-risk waters. It also requires political actors to recognise that trade corridors cannot be weaponised without placing civilian lives at risk.
The central point of this Analysis is that the reported deaths aboard the Tihamah should not be treated as an unavoidable by-product of regional confrontation. They are a warning that civilian workers are paying the price for a conflict system that has expanded from land and air into the world’s busiest maritime routes. Arsenio Dominguez, IMO Secretary-General:
“The safety of seafarers is a fundamental obligation under international law.”
Whether that obligation becomes real protection will determine the credibility of United Nation action across the Red Sea, Bab al-Mandab and the Strait of Hormuz.
