An improvised explosive device (IED) exploded in front of Radobis cinema in Haram Street, Giza, at 5.15pm, reported state TV.
The explosion killed one and injured seven at time of writing.
Early morning the Cairo Security Directorate was targeted with a car bomb-leaving four dead and 76 injured- and two separate explosions in Giza happened hours later.
