Two people were killed Wednesday in clashes between Egyptian police and student supporters of deposed president Mohamed Morsi, the health ministry said, as protests resumed on campuses nationwide.
The 13-year-old son of a Muslim Brotherhood leader was shot dead outside Beni Suef University south of Cairo, the official MENA news agency reported.
Another person was killed in Cairo, and 30 were wounded nationwide, the health ministry said.
At Cairo University, police fired tear gas at almost 2,000 protesters who threw stones and launched fireworks, an AFP correspondent said.

Morsi was ousted by the military last July 3, and his supporters have staged near-daily rallies since then.
Student demonstrations have crippled higher education, delaying until this month a new university semester that should have begun in February.
A police crackdown on the Islamists has killed more than 1,400 people in clashes, and thousands, including much of the leadership of Morsi's Muslim Brotherhood movement, have been jailed.
Morsi himself currently faces three trials on various charges, including colluding with militant groups.
He was Egypt's first democratically elected and civilian president, but his single and turbulent year in power alienated many who staged mass rallies calling for his resignation before the army stepped in.
