Human Rights Watch Classifies Houthi Attacks on Commercial Vessels as War Crimes

Human Rights Watch has declared that recent Houthi attacks on commercial vessels in the Red Sea and the Gulf of Aden constitute war crimes in at least three documented instances, asserting that the deliberate or reckless targeting of civilian crews is a grave violation of international humanitarian law.

The escalation follows a July 20, 2026, announcement by the Houthi movement imposing a maritime blockade on Saudi Arabia, which they described as a retaliatory measure against a long-standing Saudi-led air and sea blockade of Houthi-controlled regions in northwestern Yemen. These operations have targeted vessels flying the flags of various nations, including Saudi Arabia, Tanzania, and Dominica, placing civilian mariners in extreme danger.

Niku Jafarnia, a researcher on Yemen and Bahrain at Human Rights Watch, stated that the Houthis are once again endangering civilian lives within the context of their conflict with the Saudi-led coalition. She emphasized that geopolitical grievances provide no justification for deliberate or reckless assaults on civilian personnel, which are legally classified as war crimes necessitating accountability.

According to data from the United Kingdom Maritime Trade Operations and vessel tracking reports, the Houthis have targeted at least nine ships since their latest declaration. Among the most severe incidents was the attack on the Tanzanian-flagged vessel "Tihama" in the Bab el-Mandeb Strait, which resulted in the deaths of six people, including four crew members and two Yemeni coast guards, while leaving ten others injured. Although the Houthis claimed the ship was transporting military equipment, the Yemeni Ministry of Transport confirmed it was a commercial vessel carrying food supplies.

International humanitarian law mandates the absolute protection of civilians and civilian objects, requiring parties to a conflict to verify the nature of military targets and take all feasible precautions to minimize collateral damage. Human Rights Watch maintains that attacks failing to observe the principle of proportionality remain illegal, and the organization has called for an immediate and unconditional cessation of all Houthi strikes targeting civilian vessels in critical international waterways.
