DUBAI: In overcrowded hospital wards across Afghanistan, several severely malnourished children often share a single bed. Their arms are little more than bone beneath stretched skin. Their bodies have been weakened by hunger and wasting. Exhausted mothers wait beside them, many struggling with malnutrition themselves. For some children, recovery will take weeks. For others, it may come too late. Their diets can consist of little more than bread soaked in tea, sometimes watered-down yogurt — combinations that may quieten hunger but provide little of the nutrition a growing child needs.

One million children in Afghanistan are suffering from life-threatening malnutrition in a worsening new crisis hitting the country, the United Nations warned Tuesday.

Afghanistan has endured repeated periods of widespread hunger in recent decades as it has struggled through civil war and other crises.
