'Half a billion' children at hunger risk
Half a billion kids across the world are at risk because they don't have enough to eat, warns Save the Children.
The charity says rising food prices have left many parents in developing countries struggling to buy food.
Kids in one in six families surveyed had dropped out of school to help work for food.
Save the Children wants UK politicians to lead the way in tackling the problem and protecting children from food price rises.
It thinks if nothing is done, half a billion children could be physically and mentally damaged in the next 15 years.
Families in five countries were surveyed - India, Bangladesh, Peru, Pakistan and Nigeria. Save the Children says half the world's malnourished children live in these places.
