Authorities in Khartoum are forcing southerners who work for the Government in the North to register under the threat of losing salaries or jobs.
The alert comes from an official at the Sudan Council of the Churches (SCC).
The official who asked not to be named told SCR News over the phone that SCC received reporters from observers saying that the Sudan Armed Forces were forcing southerners on their ranks and file to register or lose their salary.
The same source added that the Khartoum government prepared a list of civil servants from the south to force them to register under threat of losing their job.
Yan Matthew, the SPLM spokesman, told SCR News that his brother who works for the Ministry of Finance in Khartoum was threatened either to register or leave the office.
The turn out at registration centres in the North is very low.
A source that arrived today from Khartoum said that scores of Southerners are leaving Khartoum without notice to South Sudan and some to Egypt.
