At least 600 people took part in the protest in the Sudanese capital Monday. Many shouted anti-government slogans like “Revolution Until Victory.” Plainclothes security agents were also reported on the scene near Khartoum’s main bus station — an area that saw similar unrest Sunday.
The students died amid a crackdown on demonstrations against tuition fees at the University of Gezira, south of Khartoum. Their bodies were found in a canal, and activists say the four were killed by police.
Negotiations with Darfur rebels had called for tuition breaks for those displaced by the conflict in that region.
While protests have erupted recently over soaring food prices and other grievances, there have not been the type of mass protests in Sudan like those that toppled rulers in Egypt, Libya and Tunisia.
