An improvised bomb went off Wednesday afternoon outside Cairo University, injuring six policemen and four civilians, a security source told Al-Ahram's Arabic news website.
The explosive device detonated near a faculty building across the street from the main university campus in Giza, the site of a previous deadly bombing.
The wounded have been transferred to hospitals and explosives experts were dispatched to the scene to help diffuse other explosive devices possibly planted in the area, the source added.
Cairo University, along with other campuses nationwide, has been a scene of unrest since the start of the new academic year two weeks ago, with recurrent clashes occurring between police and alleged Islamist students protesting against the government.
Police forces are stationed to secure universities from the outside, but they enter university grounds on occasion in order to quell on-campus protests. Falcon, a private security company, has been charged with securing the entrances of Cairo University among 15 other public universities nationwide.
No party has so far claimed responsibility for Wednesday's bombing.
In April, a series of consecutive explosions took place at the same spot outside Cairo University, killing a senior police officer and wounding five other security personnel.
Over a week ago, a homemade bomb exploded near the Supreme Court in downtown Cairo, wounding 12 people.
Last month, a bomb blast hit near Egypt's foreign ministry headquarters, also in central Cairo, killing two policemen and ending a months-long lull from deadly attacks in the capital. The attack was claimed by a jihadist group called Ajnad Misr (Soldiers of Egypt.)
Egyptian authorities have been battling a mounting insurgency, based in the border Sinai Peninsula, since the ouster of president Mohamed Morsi in July 2013.
Militant attacks have killed hundreds of police and army troops, but civilians have also died in the violence.
