Operation Rough Rider: US Killed More Civilians in 52 Days Than in Previous 23 Years in Yemen

Incident: March 15, 2025 · Updated: March 26, 2026

A 53-day US bombing campaign in Yemen produced an unprecedented civilian death toll, with monitoring organizations documenting at least 224 civilian deaths — matching the previous 23 years of US civilian casualties in Yemen. Strikes hit a migrant detention center, a fuel port, and a cancer hospital.

Key Facts

  • Operation Rough Rider ran from March 15 to May 6, 2025 — 53 days of sustained bombing against Houthi-controlled Yemen, with 339+ strikes hitting 800+ targets.
  • Airwars documented 33 civilian harm incidents and at least 224 civilian deaths. The Yemen Data Project documented at least 238 civilian deaths including 24 children, with 467 civilians injured.
  • In 52 days, the US killed nearly as many civilians as in the previous 23 years of US military operations in Yemen — a total of approximately 482 civilians over that entire period.
  • April 28: US strikes hit a migrant detention center in Saada holding African migrants, killing at least 68 people and injuring 47. Amnesty International called for the strike to be investigated as a war crime.
  • April 17: 14 airstrikes hit the Ras Issa fuel port, killing 84 civilians including port workers, truck drivers, civil defense personnel, and three children. HRW called it an apparent war crime.

Analysis

What Happened

Operation Rough Rider was a 53-day US bombing campaign against Houthi-controlled Yemen, running from March 15 to May 6, 2025. It was the first large-scale US military operation in the Middle East during Trump's second term and one of the most intensive American air campaigns in recent history.

The Scale

Over 53 days, the US conducted at least 339 strikes hitting more than 800 targets across Houthi-controlled territory. The campaign employed carrier-based aircraft, B-2 stealth bombers, and cruise missiles. CENTCOM reported causing over 650 Houthi casualties.

But the civilian toll was devastating. Airwars documented 33 separate civilian harm incidents and at least 224 civilian deaths. The Yemen Data Project counted at least 238 civilians killed, including 24 children, with 467 civilians injured. The total death toll across all parties reached at least 528.

The most striking statistic: in 52 days of Operation Rough Rider, the US killed nearly as many civilians as in the previous 23 years of American military operations in Yemen — a period that includes thousands of drone strikes, special operations raids, and the earlier campaign against al-Qaeda in the Arabian Peninsula.

The Worst Incidents

Ras Issa Port Strike (April 17): 14 airstrikes hit the Ras Issa oil terminal near Hodeidah, killing at least 84 civilians and injuring over 150. The dead included 49 port workers, truck drivers, civil defense personnel, and three children. The port handles 70% of Yemen's commercial imports. Human Rights Watch concluded the strikes should be investigated as an apparent war crime.

Saada Migrant Detention Center (April 28): US strikes hit a detention center in Saada Governorate holding African migrants, killing at least 68 people and injuring 47. The Intercept reported the strike killed 61 immigrants and zero combatants. Amnesty International called for the strike to be investigated as a war crime, noting the victims were migrants with no connection to the Houthi military.

Saada Cancer Hospital: A cancer treatment hospital in Saada was struck twice during the campaign, destroying a medical facility treating some of Yemen's most vulnerable patients. The bombing of hospitals is specifically prohibited under the Geneva Conventions and constitutes a war crime under the Rome Statute.

The Ceasefire

Operation Rough Rider ended on May 6, 2025, with a ceasefire between the United States and the Houthi movement brokered by Oman. The ceasefire halted the bombing but did not address accountability for the civilian casualties or reconstruction of the devastated infrastructure.

The legal analysis of Operation Rough Rider involves multiple potential war crimes:

Attacking a hospital: The Geneva Conventions provide absolute protection for medical facilities. The double strike on the Saada cancer hospital constitutes a potential war crime under Rome Statute Article 8(2)(b)(ix) — intentionally directing attacks against hospitals.

Ras Issa port strike: Striking a civilian fuel port that handles 70% of Yemen's imports implicates Geneva Convention Article 54, Protocol I — the prohibition on attacking objects indispensable to the survival of the civilian population. With 84 dead, the proportionality calculation is devastating.

Migrant detention center: Striking a detention facility holding migrants — people who had no involvement in the conflict — represents a clear failure of distinction. The victims were neither combatants nor connected to the Houthi movement. Amnesty International explicitly concluded the strike must be investigated as a war crime.

Systematic pattern: 33 civilian harm incidents across 53 days suggests a systematic failure to take feasible precautions to minimize civilian casualties, rather than isolated errors. The unprecedented civilian death rate compared to 23 years of prior operations indicates a fundamental shift in targeting standards.

Why This Is Classified Extreme

This incident receives an extreme severity classification because:

  • Unprecedented civilian death rate: More civilians killed in 52 days than in the previous 23 years of US operations in Yemen. This is not incremental escalation — it is a qualitative break.
  • Multiple probable war crimes: Hospital strikes, detention center strikes, and fuel port strikes each independently constitute potential war crimes. Combined, they form a pattern.
  • Scale: 339+ strikes, 800+ targets, 224-238 civilian deaths, 467 injured, 33 civilian harm incidents — this is a major military campaign with devastating civilian consequences.
  • Identifiable victims: Port workers, truck drivers, migrant detainees, cancer patients, children — these are not abstract "collateral damage" but specific, identifiable categories of protected persons.
  • Expert consensus: Airwars, Human Rights Watch, Amnesty International, Euro-Med Monitor, and the Yemen Data Project have all documented severe civilian harm. Multiple organizations have called for war crime investigations.

International Law Violations

The following international law provisions are implicated:

  1. Geneva Convention Article 18, Protocol I (Hospital Protection): The double strike on the Saada cancer hospital violates the absolute protection afforded to medical facilities.
  2. Rome Statute Article 8(2)(b)(ix) (Attacking Hospitals): Intentionally directing attacks against hospitals is a war crime.
  3. Geneva Convention Article 54, Protocol I (Civilian Infrastructure): The Ras Issa port strike targeted infrastructure indispensable to civilian survival.
  4. Rome Statute Article 8(2)(b)(iv) (Disproportionate Attacks): 84 dead at a fuel port, 68 dead at a migrant detention center — these represent casualties clearly excessive to any military advantage.
  5. IHL Principle of Distinction: The migrant detention center strike killed civilians with zero connection to the conflict. The port strike killed port workers and truck drivers.
  6. IHL Principle of Proportionality: The overall campaign produced a civilian death rate that had no precedent in 23 years of US operations in Yemen.
  7. IHL Principle of Precaution: 33 civilian harm incidents in 53 days suggests systematic failure to take feasible precautions.
  8. ICCPR Article 6 (Right to Life): The arbitrary deprivation of life of hundreds of civilians, including 24 children.

US Strikes on Ras Issa Fuel Port Kill 84+ Civilians in Yemen

Incident: April 17, 2025 · Updated: March 26, 2026

US airstrikes on Yemen's most critical civilian port infrastructure killed 84+ civilians including three children, port workers, truck drivers, and civil defense personnel. HRW found the strikes were an apparent war crime given the port's overwhelmingly civilian character and essential role in sustaining Yemen's population.

Key Facts

  • 14 US airstrikes hit the Ras Issa oil terminal on April 17, 2025, killing at least 84 civilians and injuring over 150, including port workers, truck drivers, civil defense personnel, and three children.
  • Ras Issa is one of three ports in Hodeidah through which approximately 70% of Yemen's commercial imports and 80% of humanitarian assistance enters the country — making it indispensable civilian infrastructure.
  • Human Rights Watch investigated and concluded in June 2025 that the strikes should be investigated as an apparent war crime, given the port's overwhelmingly civilian character.
  • Euro-Mediterranean Human Rights Monitor called the strike an unlawful use of force warranting immediate investigation and accountability.
  • The strike occurred during Operation Rough Rider, the broader US bombing campaign against Houthi-controlled Yemen that ran from March 15 to May 6, 2025.

Analysis

What Happened

On April 17, 2025, the United States struck the Ras Issa oil terminal near Hodeidah, Yemen, with 14 airstrikes, killing at least 84 civilians and injuring more than 150 others. The strikes occurred during Operation Rough Rider, the broader US military campaign against Houthi-controlled territory that ran from March 15 to May 6, 2025.

The Ras Issa oil terminal is one of three ports in Hodeidah through which approximately 70% of Yemen's commercial imports and 80% of its humanitarian assistance passes. It is the primary entry point for fuel into a country already experiencing what the United Nations has called the world's worst humanitarian crisis. The terminal's function is overwhelmingly civilian — it receives commercial fuel shipments that supply hospitals, water pumping stations, food transport, and ordinary household needs across Houthi-controlled northern Yemen.

The Casualties

Airwars and other monitoring organizations documented that 49 of the dead were port workers engaged in routine operations at the terminal. Several others were truck drivers who had been waiting in line to load fuel for transport to distribution points across the country. Two civil defense personnel were killed while responding to the initial strikes. Three of the dead were children.

The injured numbered over 150, with many suffering severe burns from ignited fuel.

Human Rights Watch published a detailed investigation on June 4, 2025, concluding that the strikes on Ras Issa should be investigated as an apparent war crime. The organization found that the port's character was overwhelmingly civilian, that the civilian casualties were disproportionate to any plausible military advantage, and that the US had an obligation under international humanitarian law to take precautions to minimize civilian harm — precautions that appeared to have been insufficient or absent.

Euro-Mediterranean Human Rights Monitor independently concluded that the strikes constituted an unlawful use of force and called for immediate investigation and accountability.

The strikes implicate several provisions of international law:

  1. Geneva Conventions Article 54, Protocol I: Objects indispensable to the survival of the civilian population — including food supply infrastructure — may not be attacked. Ras Issa is the primary conduit for fuel that powers hospitals, water systems, and food transport for millions of Yemenis.
  2. Rome Statute Article 8(2)(b)(iv): Launching an attack in the knowledge that it will cause civilian casualties clearly excessive in relation to the military advantage anticipated is a war crime. With 84 dead civilians at a commercial fuel port, the proportionality calculus is heavily weighted against the attackers.
  3. Principle of Distinction: The Ras Issa terminal processes commercial fuel imports. Striking it with 14 airstrikes raises serious questions about whether the US adequately distinguished between civilian and military objects.

Why This Is Classified Extreme

This incident receives an extreme severity classification because:

  • Scale of civilian death: 84 killed, 150+ injured in a single attack on a civilian port facility.
  • Attack on indispensable infrastructure: Ras Issa handles 70% of Yemen's imports in a country where 19.5 million people need humanitarian assistance. Destroying port capacity directly threatens the survival of millions.
  • Expert consensus: Human Rights Watch concluded the strikes are an apparent war crime. Euro-Med Monitor called them unlawful.
  • Identifiable civilian victims: Unlike many airstrikes where victim identities are disputed, the 84 dead included clearly identified port workers, truck drivers, civil defense responders, and children — all engaged in civilian activities.
  • Disproportionality: 14 airstrikes on a fuel terminal killed 84 civilians. No plausible military objective could justify this level of civilian harm at a commercial port.

International Law Violations

The following international law provisions are implicated:

  1. Geneva Conventions Article 54, Protocol I (Objects Indispensable to Civilian Survival): The Ras Issa terminal is essential civilian infrastructure supplying fuel for hospitals, water systems, and food transport. Attacking it threatens the survival of millions.
  2. Rome Statute Article 8(2)(b)(ii) (Attacking Civilian Objects): The terminal's primary function is commercial fuel import, making it a civilian object under IHL.
  3. Rome Statute Article 8(2)(b)(iv) (Disproportionate Attack): 84 civilian deaths and 150+ injuries from 14 strikes on a fuel port represent casualties clearly excessive to any military advantage.
  4. IHL Principle of Distinction: The failure to distinguish between the civilian port function and any military objective represents a fundamental violation.
  5. IHL Principle of Proportionality: Even if some military objective existed at the port, the scale of civilian casualties was grossly disproportionate.
  6. ICCPR Article 6 (Right to Life): The arbitrary deprivation of life of 84 civilians, including children, violates the most fundamental human right.

US Airstrike Kills 68 African Migrants in Yemen Detention Center

Incident: April 28, 2025 · Updated: March 25, 2026

US airstrikes killed 68 detained African migrants sleeping in a Sa'ada detention center during Operation Rough Rider. Amnesty International's investigation found no evidence the facility was a military target and concluded the strike was indiscriminate and must be investigated as a war crime.

Key Facts

  • US airstrikes hit a migrant detention center in Sa'ada, Yemen at approximately 5:00 AM on April 28, 2025, while 115 detained migrants were sleeping, killing at least 68 and injuring 47.
  • Victims were primarily Ethiopian and Somali migrants detained by Houthi authorities solely for their irregular immigration status — they were not combatants or military targets.
  • Amnesty International's investigation found no evidence the detention center was a military objective, concluding the strike was indiscriminate and must be investigated as a war crime.
  • The strike was the largest single civilian death toll in a US military operation since the 2017 Mosul airstrike, carried out under Operation Rough Rider targeting Houthi forces in Yemen.
  • Human Rights Watch called for an independent investigation and demanded the US military release its targeting intelligence and assessment of the strike.

Analysis

What Happened

On April 28, 2025, shortly before 5:00 AM local time, US military aircraft conducting Operation Rough Rider against Houthi forces in Yemen launched multiple airstrikes that hit a migrant detention center in Sa'ada, northwestern Yemen. The facility was housing 115 undocumented African migrants at the time — primarily Ethiopians and Somalis who were detained by Houthi de facto authorities solely for their irregular immigration status while attempting to cross into Saudi Arabia.

The strikes killed at least 68 detained migrants and injured 47 others. The detainees were sleeping when the bombs hit. This was the largest single civilian death toll in a US military operation since the 2017 Mosul airstrike.

Amnesty International Investigation

In October 2025, Amnesty International published an in-depth investigation titled "It Is a Miracle We Survived." The investigation found:

  • No military objective: Amnesty found no evidence that the migrant detention center was a military objective. The facility held only detained migrants — civilians taking no active part in hostilities.
  • Indiscriminate attack: The strike was classified as an indiscriminate attack under international humanitarian law, as it was not directed at a specific military objective.
  • Failure of precaution: The US military failed to take all feasible precautions to verify the target and avoid civilian casualties, as required by Additional Protocol I.
  • War crime determination: Amnesty concluded the strike must be investigated as a war crime.

US Military Response

The US military, which was conducting a broad air campaign against Houthi forces and infrastructure under Operation Rough Rider, has not publicly acknowledged the civilian death toll from this specific strike. No investigation or accountability measures have been announced as of March 2026.

The killing of 68 detained migrants who were sleeping in a known detention facility raises grave concerns under multiple bodies of international law:

Geneva Conventions Common Article 3 prohibits violence to life and person against those taking no active part in hostilities. The detained migrants were civilians held for immigration violations — they were protected persons under the laws of armed conflict.

Additional Protocol I Article 51 prohibits indiscriminate attacks — those not directed at a specific military objective. Amnesty International's finding that there was no evidence the facility was a military objective makes the strike indiscriminate by definition.

Rome Statute Article 8 defines war crimes to include intentionally directing attacks against civilian objects and against the civilian population. If the US military knew or should have known the facility was a migrant detention center, this threshold is met.

Why This Is Classified Extreme

  • Mass civilian casualties: 68 people killed in a single strike, with 47 more injured — the largest single-incident US civilian death toll since Mosul 2017.
  • Victims were detained civilians: The dead were migrants held in custody for immigration violations, not combatants. They had no ability to flee.
  • Indiscriminate attack: Amnesty International's investigation found no evidence the facility was a military target.
  • War crime assessment: A leading international human rights organization has concluded the strike must be investigated as a war crime.
  • No accountability: Nearly a year later, no investigation, acknowledgment of civilian deaths, or accountability measures have been announced.

International Law Violations

Houthi FTO Redesignation Chills Humanitarian Operations for 19.5 Million Yemenis

Incident: March 4, 2025 · Updated: March 26, 2026

The reimposition of FTO status on the Houthis threatens to deepen what was already the world's worst humanitarian crisis by chilling aid delivery, disrupting commercial imports, and creating legal risks for humanitarian workers operating in areas where more than half of Yemen's population lives.

Key Facts

  • On March 4, 2025, the State Department redesignated Ansarallah (Houthis) as a Foreign Terrorist Organization, carrying criminal penalties for providing 'material support' to the designated entity.
  • Biden had revoked the FTO designation in February 2021 specifically because of its humanitarian impact, stating it was 'due entirely to the humanitarian consequences' and would 'accelerate the world's worst humanitarian crisis.'
  • 19.5 million Yemenis — more than half the country's population — need humanitarian and protection assistance. The Houthis control all northern ports through which most humanitarian relief enters the country.
  • The FTO designation chills humanitarian operations by creating legal risks for aid organizations, banks, insurers, and commercial traders operating in Houthi-controlled territory — even when their activities are purely civilian.
  • The designation limits access to international financing, making it difficult for traders to acquire letters of credit and insurance to import food, fuel, and household goods through Houthi-controlled ports.

Analysis

What Happened

On March 4, 2025, the US State Department formally redesignated Yemen's Houthi movement (Ansarallah) as a Foreign Terrorist Organization (FTO). This reinstated the designation that had been imposed in the final days of Trump's first term and then revoked by President Biden in February 2021 — specifically because of its devastating humanitarian consequences.

What the FTO Designation Does

An FTO designation carries criminal penalties for providing "material support" to the designated organization. In the context of Yemen, where the Houthis control the most populated areas of the country including all northern ports, the practical effects are severe:

  • Humanitarian organizations face legal risk when operating in Houthi-controlled territory, even when their activities are entirely civilian — distributing food, providing medical care, running nutrition programs for children.
  • Banks and financial institutions become reluctant to process transactions related to Houthi-controlled areas, making it difficult for aid organizations to move money and for commercial importers to finance food and fuel shipments.
  • Insurers become unwilling to cover shipments to Houthi-controlled ports, disrupting the commercial supply chains that 19.5 million people depend upon for food and essential goods.
  • Commercial traders cannot easily obtain letters of credit to import goods through Houthi-controlled ports, where the majority of Yemen's humanitarian and commercial imports enter the country.

Why Biden Revoked It

The Biden administration revoked the designation in February 2021 for exactly these reasons. Secretary of State Antony Blinken stated the decision was "due entirely to the humanitarian consequences of this last-minute designation from the prior administration, which the United Nations and humanitarian organizations have since made clear would accelerate the world's worst humanitarian crisis." He called it "a recognition of the dire humanitarian situation in Yemen."

The Biden administration explicitly concluded that the FTO designation was a net negative for the humanitarian space — that it would cause more harm to civilians than any security benefit it provided.

The Humanitarian Context

Yemen was already experiencing what the UN described as the world's worst humanitarian crisis before the redesignation:

  • 19.5 million people — more than half the country's population — need humanitarian and protection assistance.
  • The Houthis control all northern ports, including the critical ports of Hodeidah through which approximately 70% of commercial imports and 80% of humanitarian aid enters Yemen.
  • The country is heavily dependent on food imports, with commercial shipments providing the majority of calories consumed by the population.

The redesignation was followed just 11 days later by the launch of Operation Rough Rider, the US bombing campaign against Houthi-controlled areas that further devastated civilian infrastructure.

Humanitarian access obligations: International humanitarian law requires parties to allow and facilitate the rapid and unimpeded passage of humanitarian relief for civilian populations in need. An FTO designation that chills humanitarian operations by creating legal risks for aid delivery impedes this obligation.

Collective punishment: The 19.5 million Yemenis living in Houthi-controlled areas did not choose to live under Houthi control and have no connection to the Houthis' military activities. A designation that disrupts their access to food, medicine, and humanitarian aid punishes them for the actions of an armed group — the definition of collective punishment under international humanitarian law.

Foreseeable harm: The humanitarian consequences of the FTO designation were not merely foreseeable — they were documented. The Biden administration revoked the designation precisely because of these consequences. Reimposing it with full knowledge of the humanitarian impact demonstrates deliberate acceptance of the harm.

Enabling classification: The designation does not itself cause casualties, but it enables humanitarian catastrophe by creating structural barriers to aid delivery, commercial imports, and financial transactions that millions of civilians depend upon for survival.

Why This Is Classified Severe

This incident receives a severe severity classification because:

  • Scale of affected population: 19.5 million people — more than half of Yemen's population — are at risk of reduced humanitarian access and commercial supply disruptions.
  • Known consequences: Biden revoked the designation specifically because of its humanitarian impact. Reimposing it with full knowledge of these consequences is a deliberate choice to accept mass civilian harm.
  • Structural barriers to aid: The designation creates systemic barriers — legal risk, financial system withdrawal, insurance refusal — that cannot be resolved through narrow humanitarian exemptions.
  • Compounding factors: Combined with Operation Rough Rider and the Ras Issa port strike, the designation is part of a broader pattern of US actions that collectively devastate Yemen's civilian population.
  • Port control: The Houthis control the ports through which most of Yemen's imports enter. Disrupting commerce through these ports threatens the food security of the entire population.

International Law Violations

The following international law provisions are implicated:

  1. IHL Obligation of Humanitarian Access: The designation creates systemic barriers to humanitarian relief delivery, impeding the rapid and unimpeded passage of aid.
  2. Geneva Conventions Common Article 3 (Humane Treatment): Disrupting access to food, medicine, and humanitarian services for civilian populations violates the obligation of humane treatment.
  3. ICESCR Article 11 (Right to Food): Measures that impede commercial food imports and humanitarian food delivery violate the right to adequate food.
  4. IHL Prohibition on Collective Punishment: Imposing economic and humanitarian restrictions that affect 19.5 million civilians for the actions of an armed group constitutes collective punishment.
  5. Convention on the Rights of the Child Article 24: Disrupting nutrition and health services for children violates their right to health.
  6. UNSC Resolution 2216: The Security Council has explicitly called for maintenance of humanitarian access to Yemen.
