Violence erupted between students supporting the ruling National Congress Party and another group from Darfur who criticised recent elections won by President Omar al-Bashir, an eyewitness said.

Several people were hurt in the clash and one of those, Mohammed Awad, "was injured and transferred to a hospital, where he died," the statement said, without giving details about the deceased.
