A civilian was killed in an explosion in the vicinity of the October 6 Police Station in Giza on Wednesday, said an official from the civil protection administration.
Magdy al-Shalaqani, director of the civil protection administration in Giza, said explosives experts moved to the scene of the blast in search of other explosive devices.
Bombings and shootings targeting security forces have surged since the ouster of Islamist president Mohamed Mursi in July 2013 following mass protests against his rule.
