By arming and backing a Saudi-led coalition fighting in Yemen, the United States, Britain and France may be complicit in potential war crimes, the United Nations said in a scathing report. The wide-ranging report from a team of investigators commissioned by the U.N. Human Rights Council found that all parties to the conflict had perpetrated possible war crimes through airstrikes, shelling, snipers and land mines, as well as arbitrary killings, torture and other abuses. The Saudi-led coalition, which is aligned with Yemen's internationally recognized government, is accused of intentionally starving Yemenis as a tactic of war and killing thousands of civilians in airstrikes. The coalition's foes, northern rebels known as Houthis, are accused of planting land mines, shelling cities and deploying child soldiers. The investigators highlighted what many of the war's critics describe as the destructive role played by the United States, Britain and France - all permanent U.N. Security Council members. The United States, in particular, provides logistical support and intelligence to the coalition, in addition to selling billions of dollars in weaponry to the group. By some estimates, the conflict has killed as many as 95,000 people, including tens of thousands of civilians, violating international humanitarian laws. Time and again, the Saudi-led coalition has promised to investigate such alleged violations. But coalition airstrikes on civilian targets - hospitals, clinics, markets, even school buses carrying children - have been unrelenting.
