Security forces and pro-Muslim Brotherhood students once again clashed at a number sites across Egypt on Monday.
Students from Ain Shams University threw stones at the security forces outside the defence ministry in Cairo. They responded with teargas, Al-Ahram Arabic news website reported.
There were similar clashes in Assiut where security forces used teargas to disperse a march by pro-Brotherhood students. Traffic jams were reported in the area.
The dean of the pharmacy at Zagazig University was struck on the head by pro-Brotherhood students demanding the release of fellow students arrested following clashes on campus last month. Students from arts and education, engineering and pharmacy faculties took part in the protest.
Police gathered at the university gates but did not intervene.
Hundreds of students demonstrated outside the walls of the university waving pictures of former president Mohamed Morsi and demanding the immediate release of their colleagues.
Earlier today, clashes took place between pro-Brotherhood students and the police at Al-Azhar University.
At the three universities, protesters demanded the release of all students arrested at earlier protests and justice for those killed by police.
Pro-Morsi protests have taken place at a number of campuses across the country since the start of term in September.
Al-Azhar University has witnessed violent clashes between security forces and students in recent weeks.
In September, a proposal by the Supreme Council of Universities to grant powers of arrest to university security guards stirred controversy.
The interim cabinet sidestepped the proposal, which had sparked fears of a return to a policy of intimidating politically active students.
Police have repeatedly entered university campuses to disperse clashes and protests in recent months.
