ASWAN, April 6 (Aswat Masriya) Aswan University indefinitely suspended classes on Sunday in light of tribal violence that has left over 20 people dead since it erupted on Friday.

Two people were killed and at least four were wounded when violent confrontations between rival tribes kicked off again in Aswan on Sunday, a hospital source told Aswat Masriya. 

The latest victims raised the death toll to 24 in clashes between Ben al-Helal and al-Dabodeya tribes in the Upper Egypt governorate. 

Egypt's interior minister, Mohamed Ibrahim, said on Sunday that reinforcements will be sent to Aswan to contain the violence.

Ibrahim said the situation is complicated because the majority of deaths are among one tribe, Egypt's state news agency said. 

He added that the authorities are exerting their utmost effort with the tribes to reach a reconciliation. 

Members of the Nubian clan have blocked the railroad in Abu al-Reesh in protest against what they described as the authorities' failure to contain the violence. 

The authorities have cordoned the area where the confrontations are taking place, a security source said. 

Egypt's Prime Minister Ibrahim Mahlab paid a visit to the troubled governorate on Saturday and ordered that a fact finding committee be formed to investigate the violence. 

Meanwhile, Egypt's military spokesman had said that the Muslim Brotherhood sparked the feud.
