A student was killed and 60 arrested as Egyptian police entered a Cairo university on Saturday to confront Islamist protesters who torched a building, amid an intensifying crackdown on the Muslim Brotherhood, officials said. The unrest followed nationwide repression of Islamist protests on Friday after the military-installed government listed the Brotherhood, the movement of deposed president Mohamed Morsi, as a terrorist organisation. A hospital official said a 19-year-old student was shot dead in the clashes at the Al-Azhar University campus, where pro-Morsi students have regularly staged protests since his overthrow by the army in July. The students had entered the commerce faculty during an exam and set it alight, before police burst into the campus and fired tear gas. A police official said 60 of the students were arrested after the fire on the first two floors of the building was brought under control. The violence comes a day after five people were killed in clashes across Egypt, according to a health ministry tally on Saturday, as police stamped out Brotherhood demonstrations. The interior ministry said 265 protesters were arrested. The military-installed government has banned protests by Brotherhood members, after it listing the Islamist movement as a terrorist organisation this week. The designation carries harsh penalties, with Brotherhood leaders facing possible death sentences and protesters looking at up to five years in prison. The movement has held near-daily protests since the military ousted Morsi on July 3, despite a crackdown that has killed more than 1,000 people, mainly Islamists, and imprisoned thousands. It was listed as a terrorist group in a drastic escalation of the months-long crackdown after a suicide bombing killed 15 people in police headquarters north of Cairo on Tuesday. The bombing was claimed by an al-Qaeda-inspired group that has led attacks on the military and police. Five people were also wounded in a bomb that targeted a bus in Cairo on Thursday. On Friday, the Islamist movement, which had dominated elections following the overthrow of strongman Hosni Mubarak in early 2011, said it would remain committed to peaceful protests. “The Muslim Brotherhood declares it is innocent of any violent incident that has or will be committed,” the Islamists said in a statement. The interim government has decapitated the 85-year-old movement since Morsi’s overthrow, imprisoning him and most of the movement’s leadership and putting them on trial. It has also sought to quell a surge in attacks in the Sinai that has killed more than 100 soldiers and policemen, as bombings and shootings spill over into mainland Egypt. Ansar Beit al-Maqdis, the group that claimed responsibility for Tuesday’s police headquarters attack, had tried to assassinate the interior minister Mohamed Ibrahim in a suicide car bombing outside his home in Cairo in September. The militant group has criticised the Brotherhood for its style of electoral politics, but authorities say the movement has links with militant groups, without offering proof. Morsi himself and top Brotherhood leaders will face trial with top Brotherhood leaders for allegedly colluding with militants to carry out attacks. Morsi, Egypt’s first democratically elected president, had ruled for one turbulent year before the military overthrew him, following mass protests demanding the Islamist’s resignation.
