Millions of people in Sudan fleeing .
In December I was in South Sudan with the aid organization CORDAID .
Millions of people fleeing violence.
Refugees from Sudan cross the border into South Sudan in large numbers every day. There are several near the town of Renk
camps for the refugees but there is too little help. Not enough food, tents and medical care. Many children are malnourished and need help.
Every day, groups travel further into the country with trucks and boats across the Nile.
