There is growing evidence of what aid agencies are calling a humanitarian catastrophe in South Sudan.

More than 100,000 Sudanese refugees have arrived in Batil and other camps from just over the border in Blue Nile, where a civil war began nearly a year ago.

The aid agency Medecins Sans Frontieres (MSF) says the mortality rate in the Batil refugee camp is substantially over the emergency threshold.

James Copnall reports from Batil.
