"The number of Iraqi children who are born underweight or suffer from malnutrition has increased sharply since the US-led invasion, according to a report by Oxfam and a network of about 80 aid agencies. The report describes a nationwide catastrophe, with around 8 million Iraqis - almost a third of the population - in need of emergency aid. Many families have dropped out of the food rationing system because they have been displaced by fighting and sectarian conflict. Others suffer from the collapse in basic services caused by the exodus of doctors and hospital staff."
