Famine looms in South Sudan war zones as aid agencies blocked

Weeks after UN-backed experts warned that thousands are dying of starvation in South Sudan war zones, aid agencies say they cannot access areas to stave off famine because of "spiralling" violence.

Last month, UN agencies said 30,000 people were starving to death in Unity state, with Integrated Food Security Phase Classification (IPC) experts warning of a "concrete risk of famine" before the end of the year if fighting continues and aid does not reach the hardest hit areas.
