CAIRO -- An explosive device went off Thursday outside a university campus in the Egyptian capital, injuring at least four people on a passing bus, witnesses said.
A short time later, another small blast went off in the area. Officials said the devices appeared to be homemade bombs.
The first blast, which was loud but relatively small, took place in a roadway near student dormitories at Al-Azhar University in the Nasr City district of Cairo, according to the bus driver and passersby. There was little damage other than to the bus.
There was no immediate claim of responsibility. Police quickly converged on the scene and cordoned off the area.
