Egypt has been suffering from a wave of militant attacks targeting security forces across the country.
While the country had suffered from a decade long armed insurgency in Sinai, attacks on security personnel have taken place to other governorates including the capital since the 2013 ouster of Islamist president Mohamed Morsi.
