(The Guardian) – In an overcrowded nutrition clinic at Alsalkhana hospital in Hodeidah, one of Yemen’s largest cities, around 30 anxious mothers wait with resigned patience to have their children weighed and measured. The first thing you notice about Ayesha*, aged seven months, is her stick-thin legs and distended tummy. She weighs just 3.5kg – the average weight of a newborn baby in the UK. When the doctor measures her upper-arm circumference, the tape goes deep into the red zone, indicating dangerous malnutrition.
