"Due to the escalation and volatility of the violence, the ICRC has had to temporarily move its team to a safer location further away from the hostilities," Jacob Kurtzer, the ICRC's South Sudan spokesman, said in an email.
"It continues to work on monitoring the situation and is on standing ready to return as soon as security conditions permit with a view to respond to the considerable humanitarian needs."
UNABLE TO KEEP WALKING
An MSF medical team is on the road 20km south of Bentiu, helping fleeing civilians.
"We see that a lot of people are leaving Bentiu on foot or with cars," said Gorgeu. "We sent a team from Leer to the road from Leer to Bentiu today to see how many people we are talking about, what would be the needs, where are they going, to see how we can provide assistance."
The MSF team will see where they can put up water points and basic health clinics to support people on the move, and those who are very ill and unable to keep walking will be taken to hospital in Leer, Gorgeu said. The health of women and children walking long distances with luggage can deteriorate quickly, he said.
There is limited humanitarian access to many towns in northern South Sudan because of the fighting. Aid agencies have called for a ceasefire to allow food, medicine and plastic sheeting and other emergency aid to be delivered to the displaced.
