CAIRO: A bomb exploded outside Egypt’s largest and most prominent university in the country’s capital on Wednesday, wounding 10 people, including six policemen, the Interior Ministry said.

The bomb, described as a rudimentary device, went off following clashes between police and students who were protesting outside the sprawling campus, the ministry said.

It was the second bombing outside Cairo University in the past six months.

Universities have seen regular protests since the military’s ouster of President Muhammad Mursi last year. Earlier this month, clashes between pro-Mursi students and police erupted again on the first day of the school year at several Egyptian universities.

After Wednesday’s explosion, security forces quickly cordoned off the area, according to footage from private television stations. Security officials said explosive experts were combing the area.

The Interior Ministry said four of the wounded are officers and two are conscripts, while the remaining four are civilians.

In April, three bombs exploded outside Cairo University’s main campus, killing a police general and wounding seven others, including several top police officers. The bombings came at the height of clashes between students and police near the university.

Ajnad Misr, or “Egypt’s Soldiers,” claimed responsibility for the April bombing. In a statement, it said it was waging a campaign of retribution and that the slain police general had been involved in killings of protesters. It said the attack also came in response to increased detentions of female protesters.
