In the latest in a series of militant attacks, four bombs exploded in Greater Cairo on Friday morning and two more in the afternoon, leaving no casualties, state news agency MENA reported.
One of the bombs targeted an electricity unit in the southern Cairo suburb of Maadi, causing damage to three cars. Another was planted in a central square in Zaytoun, an eastern Cairo neigbourhood.
On the western outskirts of Cairo, twin bomb attacks targeted a gas supply unit in 6 October city.
Later in the day, two crude bombs went off in the densely populated districts of Al-Marg and Al-Amireya in northeast Cairo. No injuries have been reported.
On Monday, a string of bomb attacks hit the capital, killing two people outside a courthouse in central Cairo.
Bombings and shootings have become commonplace in the capital and other parts of the country amid an uptick in militant insurgency since the 2013 ouster of Islamist president Mohamed Morsi.
The bloodiest attacks have occurred in the border Sinai region, mainly targeting police and military personnel. The violence has killed hundreds in the past 18 months and also led to civilian casualties.
