NAIROBI, Kenya - An internal UN security report says intelligence agents from northern Sudan posed as Red Crescent workers and ordered internally displaced persons to leave a UN-protected camp.

The report, obtained by The Associated Press on Thursday, said agents from the National Security Service donned Red Crescent aprons at a camp in Kadugli, Southern Kordofan.

The report said the agents told the refugees to go to a stadium for an address by the governor and for humanitarian aid. They were threatened with forced removal.

Sudan's military this month has attacked communities in Southern Kordofan aligned with Sudan's south. The south secedes from the north on July 9 but violence along the north-south border are rising.
