The struggling nation of Yemen is on the brink of what could become the worst famine the world has seen in decades. The country’s economy has collapsed amid a three-year-old war between a Saudi-led coalition and Houthi rebels. About 8.4 million are what the UN calls “severely food insecure” and at risk of starvation. To make matters worse, it’s increasingly clear that the humanitarian disaster in Yemen isn’t an unintended side effect of the war - but a deliberate effort to starve the population.
