Three police conscripts were injured on Saturday outside Arish, North Sinai, when a roadside bomb exploded as their police armored vehicle was passing by.
Security sources and eyewitnesses said a bomb was planted next to the Arish-East of Qantara international road, in the al-Masaeed area, west of Arish.
Security sources were unable to identify the terrorists responsible for the attack.
The three conscripts were transported to hospital for emergency treatment.
Egyptian military and security forces have been battling a mounting insurgency in Sinai since the removal of former President Mohamed Morsi in June 2013. Militants linked to the Islamic State terrorist group frequently conduct ambushes, mortar attacks and roadside bomb attacks in the North Sinai governorate.
In one of the largest single attacks, at least 15 police personnel were killed in an assault on a checkpoint in Arish, North Sinai. According to news reports, the attack was initiated by a car bomb at the checkpoint, followed by mortar fire.
Militants from the Sinai Province terrorist group, which is affiliated to Islamic State, later claimed responsibility.
In a typical attack, militants will detonate explosives and then fire on ambulance crews when they arrive to treat the casualties.
