A consortium of UN and other agencies says that famine is spreading across the war-ravaged country. The group, known as the IPC - the "Integrated Food Security Phase Classification" - say that five areas in the west and south of Sudan are already in famine. We hear about the details of the report and from one of the agencies working in the city of Nyala in the South.

Also on the programme; we hear from Mozambique's capital Maputo where protests are continuing over disputed presidential election results; and a NASA spacecraft attempts the closest ever approach to the Sun.
