On Tuesday, a bomb squad defused an IED outside the Faculty of Agriculture at al-Azhar University, a security source said.
The source added that police is currently combing the area in search of more explosives. Three molotov cocktails were also found.
Al-Azhar University has been the stage for frequent clashes between security forces and students loyal to deposed president Mohamed Morsy and the Muslim Brotherhood.
The university’s administration on Monday ordered students to be evacuated from campus after violent clashes between Morsy backers and police.
The encounters left two police officers and one student injured, according to state-run news agency MENA.
The university’s administration decided to proceed with examinations despite the unrest.
