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

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.

  • 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.

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

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.

  • 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.

Houthi FTO Redesignation Chills Humanitarian Operations for 19.5 Million Yemenis

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.

  • 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.

US Airstrike Kills 68 African Migrants in Yemen Detention Center

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.

  • 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.
