The conflict between the Saudi-led coalition and Houthi forces has exacerbated the dire humanitarian situation and taken a terrible toll on Yemeni civilians. The coalition's scores of indiscriminate airstrikes have killed and wounded thousands of civilians in violation of the laws of war. Houthi forces have fired artillery indiscriminately into Yemeni cities and launched rockets into populated areas of Saudi Arabia. The coalition has used banned cluster munitions; the Houthis banned landmines. The Houthis, pro-government forces, and United Arab Emirates-backed forces have arbitrarily detained, abused or "disappeared" scores. The US conducted ground raids and drone strikes against Al Qaeda in the Arabian Peninsula and the local Islamic State affiliate, causing civilian casualties.
