A student was killed and 21 others were wounded during an Islamist demonstration at Cairo University on Thursday, the health ministry said, as Egyptian authorities continued their crackdown on supporters of ousted President Mohammad Mursi Al Arabiya reported.
The dead man was Mohammad Reda Mohammed Abdo, 19, a second-year engineering student, said senior health ministry official Ahmed al-Ansari and forensic authority spokesman Hisham Abdul Hamid, according to AFP.
The circumstances of his death were not immediately known.
The protests came a day after a court handed heavy sentences 21 women and teenage girls found guilty of obstructing traffic during a pro-Islamist protest last month.
The 14 women were imprisoned for 11 years, while the seven under the age of 18 were sent to juvenile prison.
Morsi supporters have regularly staged protests against the military since it ousted the Islamist leader on July 3 and, in recent months, have increasingly staged demonstrations in universities.
Abdo's death is the first since interim authorities passed a disputed law requiring that organisers must give a three-day written notice before holding a demonstration.
On Tuesday, police broke up two small protests in Cairo by secular and youth movements to oppose the law, widening the authorities' crackdown which so far has targeted Islamists.
And on Wednesday, authorities ordered the arrests of two prominent activists who led the revolt against long-time ruler Hosni Mubarak in 2011.
The suppression of mainly secular youths is seen as the opening of a new front by the authorities, which justified Mursi's ouster by saying it was responding to massive demonstrations against his rule.
