Security forces fired tear gas at supporters of deposed president Mohamed Morsi on Friday after they attacked the United Arab Emirates embassy in Cairo's Heliopolis.
Protesters assaulted the embassy's guards, according to Al-Ahram's Arabic website.
The UAE, a staunch opponent of the Muslim Brotherhood – the group from which Morsi hails – has been among several Arab states backing the former president's ouster.
According to eyewitness accounts, protesters also threw Molotov cocktails at a tram line near Al-Nozha street in Nasr City, setting a carriage on fire. They also set fire to a nearby kiosk.
Police fired tear gas at pro-Morsi students at Al-Azhar University, located in Nasr City, to prevent them from protesting outside the campus grounds.
The students were marking 100 days since the violent August dispersal of two pro-Morsi protest camps at Rabaa Al-Adawiya mosque and Nahda Square.
According to Aswat Masriya news website, rocks and other objects were hurled between protesters, police and local bystanders in the vicinity of Al-Azhar University.
Egypt's universities have witnessed regular protests by supporters of the deposed president since the start of the academic year in September.
On Wednesday, a student from Al-Azhar University was killed in clashes with security forces on campus.
The dead student was shot in the head with a birdshot pellet at around midnight.
According to Al-Ahram, clashes also took place near Nasr City's Workers University on Friday, where security forces arrested several Muslim Brotherhood members for allegedly possessing guns and destroying four vehicles, included one owned by the police.
Several mid- and high-ranking Muslim Brotherhood members are now behind bars, following a security crackdown against the group in the wake of the August sit-in dispersal.
