UN humanitarians in Sudan issued a fresh alert on Friday about pervasive food insecurity and looming famine.
After nearly a year of brutal civil war between rival militaries, food production has been hit and communities face acute shortages of other essential resources such as water and fuel.
More than eight million people are believed to have been uprooted from their homes with tens of thousands killed or wounded.
The World Health Organization (WHO) meanwhile has warned that every seventh child under five is acutely malnourished and 70 to 80 per cent of health centres are no longer functioning.
WHO spokesperson Christian Lindmeier said that five million people were "on the brink of famine" in areas affected by conflict:
"With the lean season expected to start soon and without unhindered access for aid, the situation will only worsen in the coming months", he added.
