Egyptian security forces and supporters of the country's ousted president Mohamed Morsi clashed Wednesday, leaving one person dead.
Egyptian officials say at least eight people were wounded in the fighting near Cairo University.
Riot police fired tear gas at students demonstrating against this week's court ruling that sentenced 529 Muslim Brotherhood members to death for murdering a police officer, attacking a police station and other acts of violence.
Security forces and students also clashed in the Nile Delta city of Zagazig.
Also Wednesday, Egypt's state-run al-Ahram newspaper reported the country's army chief, General Abdel Fattah el-Sissi, met with military leaders to say he is resigning as defense minister so he can run for president. The general was expected to announce his decision in a broadcast statement.
Sissi, who also is defense minister, was the principal military figure in last year's ouster of Islamist President Mohamed Morsi, following months of mass protests against his rule. The general's decision to run for president has been widely expected, and would have the explicit backing of Egypt's powerful military.
