GENEVA - The United Nations and international aid groups say the spreading conflict between North and South Sudan is driving thousands more people from their homes.
The International Organization for Migration says almost 106,000 people are displaced in the Abyei region alone.
The UN aid coordination office says heavy fighting occurred Thursday in South Kordofan State and the northern part of Unity State.
The two areas lie on either side of the disputed border between North and South Sudan.
UN spokeswoman Elisabeth Byrs says aid agency offices in the capital of South Kordofan, Kadugli, have been looted.
She told reporters in Geneva on Friday that most local and international aid staff have fled the Kadugli area.
