“There is a very serious humanitarian crisis there; it is a very worrisome situation,” Mr Chambas said.
UNHCR says the Sudan crisis is one of the largest crises the agency has faced, with many children and women displaced.
The minister said the influx of displaced persons due to the Sudan crisis further compounded the existing humanitarian catastrophe the country was already going through
The figure brings 2,858 Nigerians evacuated by the federal government since the war broke out in Sudan in April.
He said the crisis had so far claimed the lives of about 200,000 people, in addition to the millions of displaced people taking refuge in neighbouring countries.
But both sides have made it clear they would only discuss a humanitarian truce, not negotiate an end to the war.
The UN, AU and IGAD issued a statement appealing to the sides “to create necessary conditions during this period for the civilians to seek safe shelter, food and medical care.”
The UN Humanitarian coordinator in South Sudan has called for joint action to address the aid crisis in the country and end attacks against civilians and humanitarian workers.
