Thousands of Egypt’s al-Azhar University students have demonstrated in Cairo for the third consecutive day, demanding the reinstatement of the country’s ousted President Mohamed Morsi.

Around 4,000 students staged protests on al-Azhar campuses on Monday, and condemned the military-backed government’s crackdown on Muslim Brotherhood and Morsi supporters, Reuters reported.

Security forces arrested more than 40 students during the demonstration.

On Sunday, fierce clashes erupted between Egyptian security forces and al-Azhar University students. The security forces fired teargas to disperse the protesters.

Morsi’s supporters have been holding weekly rallies against the army-backed government for its deadly crackdown on Brotherhood supporters that has led to hundreds of deaths and detentions.

Egypt has been experiencing unrelenting violence since July 3, when the army ousted Morsi’s government, suspended the constitution, and dissolved the parliament. It also appointed the head of the Supreme Constitutional Court, Adly Mahmoud Mansour, as the new interim president.

Mansour’s government has launched a bloody crackdown on Morsi supporters and arrested thousands of Muslim Brotherhood members, including the party’s leader, Mohamed Badie, who was detained on August 20.

Hundreds of supporters of the group have been killed in clashes with army since then.

Morsi himself is scheduled to be tried next month on the charge of inciting the killing of his opponents while in office.
