Friday was a day of violent clashes in Egypt, between supporters of the Muslim Brotherhood and the police at a level unparalleled in more than two months.
Al Ahram cited the ministry of health as saying on Saturday that 14 people were killed and 62 injured in clashes across the country on Friday.
Earlier on Saturday, a medical source had told Al-Ahram 17 people were killed during the clashes.
17 police officers were also injured, according to a senior security source.
Protesters died in Cairo, Alexandria, the Suez Canal city of Ismailia, Fayoum and Minya in Upper Egypt, according to the Egyptian health ministry.
The police said it arrested more than 258 Brotherhood supporters including some possessing explosives and weapons.
Clashes continued into the night east of the capital at Gisr El-Suez Street and at the other end of the city's outskirts at Al-Talbiya area near the pyramids.
In Nasr City – which had calmed down amid a heavy police presence, a public bus was smashed and several cars were shattered in the violence.
Police fired teargas at a student march at the nearby Al-Azhar University, a major scene of Islamist protests in recent weeks, state news agency MENA said.
Brotherhood supporters set the Faculty of Agriculture building at Al-Azhar University on fire and damaged five administrative offices inside, Al-Ahram reported.
More than 1,000 people, mainly Morsi supporters, have been killed since July 3 when he was ousted, and authorities have rounded up some 2,000 Islamists, including most of the leadership of the Muslim Brotherhood.
The tensions deepened last week when the interim Egyptian government blacklisted the Muslim Brotherhood as a "terrorist organization".
The terror designation came a day after a massive suicide car bombing in the Nile Delta city of Mansoura killed 16 people and wounded more than 100.
