Two police officers were killed when an IED exploded inside an armoured vehicle in North Sinai's Al-Arish, the interior ministry said in a statement on Friday, Ahram News reports.
Five conscripts also suffered minor injuries in the explosion near Ahmed Orabi school, and were transferred to hospital.
The two officers who were killed held the ranks of first lieutenant and captain.
The ministry said investigations are underway to apprehend the perpetrators.
Egypt's army has been fighting an insurgency for decades, which spiked following the ouster of president Mohamed Morsi in 2013. Hundreds of militants and security forces have been killed since.
The army said earlier this month that they had killed 26 militants in raids in North Sinai as part of the ongoing "Martyr's Right" operation to rid the area of extremism, which began in September 2015.
