The spokesman of the world's oldest Islamic university resigned in order to join the anti-government protest in Cairo's Tahrir Square, the newspaper al-Masri al-Youm said on its website Friday, DPA reported.
Al-Azhar University's Mohamed Refaa al-Tahtawy said he would remain in the square until President Hosny Mubarak resigns.
Attacks on the reformist camp by pro-Mubarak supporters contributed to his decision to join the protest, al-Tahtawy said.
"Confrontation with the regime will continue until the president responds to the demands of people. The president stepping down is only the start to solving the crisis," he said.
