Hundreds of thousands of people fleeing the fighting in South Sudan are still too terrified to return home, despite a peace agreement signed last year.
And the head of the UN mission in South Sudan (UNMISS) told Sky News that militia groups still recruit child soldiers by force.
David Shearer warned that there would be serious consequences for several armed groups if the recruitment continued.
He said: "We are saying stop, stop [recruiting]you have to live according to your words and many of these people will say they will not make it … but if we find out you are [recruiting] we will name you and be ashamed we will take action.
"These guys have more value than senior leaders. "
South Sudan is the youngest nation in the world , gaining independence in July 2011 after years of conflict with Sudan.
But only two years later, the country returned to fighting after President Salva Kiir fired his deputy, Riek Machar, accusing him of planning a coup.
A long period of five years There followed a civil war that saw more than four million people fleeing the violence, making it one of the worst displacement crises in the world.
About a third of the population of the country has now been eradicated.The previous ceasefire attempts quickly collapsed
The latter – which saw the two political rivals meeting and sign a peace agreement last August – was considered much more confident.
But most of those displaced have refused to go home, saying they are still too scared, and some are telling us the attacks are continuing.
Nearly 200,000 of them are currently repairing civilian sites (known as POCs) in six UN bases across the country. But now the UN has actually notified their complaint, telling them they will have to leave soon.
"We were right to open the gates when people needed protection, and some have been in these camps for a considerable period … some for five years," Shearer told Sky News in the capital, Juba.
"But with an agreed-upon peace agreement and improved security, it is far more preferable for people to return home, term deadline for families."
Some people were persuaded to go home but they are very much in the minority and when we visited two of the camps near Juba, we found huge expanding communities living behind the barbed wire and depended on regular UN security patrols.
A mother, Chol Jong, told us that seven of her children had been separated from panic by her for escaping th and violence.
