A security patrol exchanged fire with unknown assailants Sunday in Fayoum, with no reported causalities on either side.
The gunmen shot at the patrol men in the early hours of the day in the outskirts of the city, state news agency MENA reported.
The city witnessed protests Saturday night, against the death sentences handed down to former president Mohamed Morsi and scores of Muslim Brotherhood members and leaders earlier in the day.
Insurgent activity targeting policemen and a concomitant high security presence have been on the rise since the ouster of Morsi in 2013.
Militants target security personnel either by drive-by-shootings or bomb attacks. Vital facilities including power stations, electricity pylons and telecommunication branches are amongst the targets.
The frequency of these attacks is at its highest in the restive Sinai Peninsula, followed by Greater Cairo and other governorates.
