[MSF] Although the annual peak in malnutrition cases should now be over in Nigeria, dozens of severely malnourished children continue to occupy beds in Médecins Sans Frontières' (MSF) intensive therapeutic feeding centre in Katsina City, in the country's northwest. Some doctors, like Dr Alibaba Nurudeen, who works in the centre, say that this is only the tip of the iceberg in a region that is also facing a wave of severe violence.
