Al-Azhar University, Egypt's largest Islamic educational institute, expelled on Sunday 51 students for involvement in pro-Muslim Brotherhood protests.
The university's deputy head, Tawfeeq Noureddin, told Ahram Online that investigations showed the students had violated university rules.
Investigations by the university administration and the public prosecution found that the students were involved in violence and riots on campus, university president Abdel-Hay Azab said in a statement reported by state news agency MENA.
Al-Azhar University has witnessed a wave of protests and violent clashes between anti-government students and security forces since the ouster of Islamist president Mohamed Morsi in July 2013.
Thousands of students have been arrested and tried in accordance with a controversial protest law, while dozens of others have been expelled for their involvement in protests in the past few months after the Supreme Council of Universities said it would expel students and staff members involved in violence.
