Students at Mansoura University clashed on Tuesday in arguments over the current political crisis.
The disputes led to violent conflict between students who support the military and others who support ousted former president Mohamed Morsi.
Each faction accused the other of firing a teargas canister, Ahram's Arabic website reports.
Several injuries were reported and two vehicles parked inside the campus were destroyed.
Mansoura University student union president Mostafa Mounir told Ahram Online he is surprised at the unfolding of events, as various factions of the student body are aware of one another's positions, having protested in front of each other on a number of occasions without resorting to violence.
Mounir said he agreed on a code of ethics with student bodies representing different political forces three weeks before Tuesday's clashes. The code promotes tolerance, diversity and respect for the freedom of speech of all students.
“Trouble only occurred when workers attacked anti-coup protests,” said Mounir, who is himself a member of the Muslim Brotherhood.
“Political activism is an integral part of character building and shouldn’t be viewed as a threat to education. Protests were rampant after January 25 and no one objected. The rhetoric we are hearing post-June 30 resembles that of the Mubarak era,” Mounir added.
In recent days, protests have taken place on a number of other university campuses, traditionally sites of political and Islamist activity in Egypt.
At least 29 were injured Sunday during clashes on three university campuses between supporters and opponents of deposed president Mohamed Morsi, some armed with guns and Molotov cocktails, state media and security sources reported.
