There has been a crackdown on "suspected rebels" in the capitol city of Khartoum. However, there are reports that this is more like a crackdown on persons of Darfuri descent, particularly those belonging to the Zaghawa tribe of the rebel movement JEM.
for an article on the roundups, and read below for an excerpt:
"If you are dark and resemble the people of the Zaghawa tribe … they will take you away," said Fatema Daoud, 22, who belongs to a Darfur rebel faction. "If they hear you speaking the Zaghawa dialect, they will arrest you. My people are living in panic."
