Two explosive devices detoned late Friday in Fayoum, south of the Nile Delta, near the local traffic department, causing damage to parked cars and slightly injuring a police cadet.
The only injured sustained a cut in his leg by a fragment of glass that hit him as a result of the explosion.
Al-Ahram's Arabic website reported that a third explosive device was defused by a bomb team in the same area, which was secured upon the two explosions.
Egypt has been hit by a wave of bomb attacks of different sizes for over a year following the ouster of Islamist president Mohamed Morsi in 2013 following nationwide protests against his rule.
