A passerby was killed and another injured when an IED exploded on a road in Greater Cairo's Ain Shams district on Friday, Al-Ahram’s Arabic website reported.
A security official told Al-Ahram that the device was targeting a passing security convoy but instead hit two civilians.
Attacks against security forces have become common in recent years but are concentrated in North Sinai, where Egypt's army and police are battling an entrenched Islamist insurgency.
Last week, a brigadier general was shot dead in front of his house in Obour City, on the outskirts of Cairo. Adel Rajaaie had previously been deployed in North Sinai.
