The Gulf States and the Houthis have medium to long-range precision-strike weapons at their disposal and have repeatedly employed them in attacks that evidently violate International Humanitarian Law (IHL) norms. Governments of major arms exporting states should reassess their arms exports to Saudi Arabia and the United Arab Emirates in the light of such IHL violations and call on Tehran to invest its share in containing the flow of components and complete weapon systems. Accountability in its various forms emerges as a central mechanism to prevent future international human rights violations.
