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.
\nOver 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.
\nBut 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.
\nThe 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.
\nRas 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.
\nSaada 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.
\nSaada 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.
\nOperation 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.
\nThe legal analysis of Operation Rough Rider involves multiple potential war crimes:
\nAttacking 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.
\nRas 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.
\nMigrant 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.
\nSystematic 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.
\nThis incident receives an extreme severity classification because:
\nThe following international law provisions are implicated:
\nOn 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.
\nThe 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.
\nAirwars 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.
\nThe injured numbered over 150, with many suffering severe burns from ignited fuel.
\nHuman 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.
\nEuro-Mediterranean Human Rights Monitor independently concluded that the strikes constituted an unlawful use of force and called for immediate investigation and accountability.
\nThe strikes implicate several provisions of international law:
\nThis incident receives an extreme severity classification because:
\nThe following international law provisions are implicated:
\nOn 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.
\nThe 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.
\nIn October 2025, Amnesty International published an in-depth investigation titled \"It Is a Miracle We Survived.\" The investigation found:
\nThe 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.
\nThe killing of 68 detained migrants who were sleeping in a known detention facility raises grave concerns under multiple bodies of international law:
\nGeneva 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.
\nAdditional 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.
\nRome 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.
\nOn 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.
\nAn 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:
\nThe 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.\"
\nThe 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.
\nYemen was already experiencing what the UN described as the world's worst humanitarian crisis before the redesignation:
\nThe 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.
\nHumanitarian 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.
\nCollective 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.
\nForeseeable 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.
\nEnabling 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.
