A new United Nations report says more than 1,100 children have been killed during the war in Yemen—and that the majority of these children were killed by U.S.-backed, Saudi-led airstrikes. The U.N. also described the ongoing humanitarian crisis in Yemen as an “entirely man-made catastrophe.” The ongoing war has left more than 7 million people on the brink of famine. The U.S.-backed bombing campaign has also devastated Yemen’s health, water and sanitation systems, sparking the world’s worst cholera epidemic, with 600,000 people affected.
