CAIRO: Sudanese activists said the security forces have dealt with protesters over the last three days with unprecedented violence, saying that Sunday was the bloodiest day in Sudanese street history. Sudan's capital Khartoum has seen mass protests, which started on Friday, when hundreds of students took to the streets in protest of high costs of living and plans to cancel fuel subsidies. Sudan has economically suffered since the oil rich south gained its independence in July of last year. The government is facing a budget deficit and believes that canceling subsidies will save about two billion dollars annually. The protest was met with massive violence from police, reported the pro-change group Change Sudan Now. “We call for an immediate end to violence against peaceful protesters who are expressing legitimate demands,” the group said in statement released Monday online. The group called on the media and non-governmental groups to document what they called “crimes against the protesters” in Sudan. Activists reported that police opened fire on protesters, but no deaths have been reported to date. Sudan, whose the Arab Spring wave of change seemed to pass without protests, is looking in the face of new challenges, with increasing food prices and soaring gas prices, and it is unlikely for protests to stop.
