(Save the Children) – A new survey from Save the Children has found that up to half of all under-fives are acutely malnourished in some parts of north-east Nigeria where it is feared 200 children could die every day in a hidden hunger crisis. Screenings carried out between June and last month regularly found between 40% and 50% of children under-five to be acutely malnourished in some places. The figure could be even worse in areas that are out of reach because of insecurity, the charity says. Save the Children is warning that the hunger crisis threatens to overwhelm a desperately under-funded humanitarian response.
