Violent clashes erupted Sunday afternoon between pro-Morsi students and security forces outside Cairo University with several students injured.

The clashes began when 10 pro-Morsi students from "Students Against Coup" (SAC) organised a rally that roamed Cairo University grounds and then left campus heading from Al-Nahda Square to Dokki Street where they were met by security forces.

The students chanted slogans against this week's constitutional referendum, describing it as a scandal and demanding the reinstatement of ousted president Mohamed Morsi. The students also chanted against the interior ministry. SAC has been calling for a boycott of the referendum.

Security forces dispersed the protest with tear gas while students hurled rocks and Molotov cocktails, torching a police kiosk near Cairo University. Police managed to force the students to retreat back to Cairo University campus where they were continued to protest and hurl rocks at security forces.

Cairo University in Giza and Al-Azhar University in Cairo, along with Ain Shams University, also in the capital, have witnessed frequent violent clashes between security forces and pro-Morsi students since the start of the academic year.
