The Saudi Arabia-led coalition killed several dozen civilians in three apparently unlawful airstrikes in September and October 2016. The coalition’s use of United States-supplied weapons in two of the strikes, including a bomb delivered to Saudi Arabia well into the conflict, puts the US at risk of complicity in unlawful attacks.

The attacks underscore the urgent need for foreign governments to suspend all arms sales to Saudi Arabia and for the United Nations human rights office to send additional investigators to Yemen to carry out credible investigations of alleged abuses by the coalition, the Houthis and their allies, and all other parties to the conflict, Human Rights Watch said.
