An improvised bomb exploded Friday near a police station in the Talbiya district in Giza, Al-Ahram Arabic news website reported, in the third bomb attack of the day on security sites.
The explosion, which hit a police station near the Giza pyramids, caused no fatalities, an interior ministry official told state TV.
The bomb was placed beneath a billboard on a traffic island in Giza's usually busy Al-Haram Street, some 50 metres from a police station.
It went off hours after a car bomb outside a police headquarters in central Cairo killed four people.
