"Explosive experts have successfully dismantled eight improvised explosive devices that targeted police personnel and facilities across the province of Cairo," the source, who requested anonymity, told The Anadolu Agency.
The source said that seven other bombs had been defused in the Giza, Beni Sueif, Minya, Aswan, Menoufiya and Fayoum provinces.
Police also arrested ten people who they claimed "belong to a Muslim Brotherhood cell in the Alexandria province," according to a statement issued by the Interior Ministry.
"We found them with three machine guns, nine shotguns, and large amounts of ammunition, explosive devices, electrical equipment, mobile phones and bomb-making tools," the ministry said.
Egyptian authorities often accuse the Muslim Brotherhood of planting bombs, even though other groups – such as Agnad Masr ("Soldiers of Egypt") – claim responsibility for attacks.
The police say these groups operate under the umbrella of the Muslim Brotherhood – allegations the Brotherhood has consistently denied.
The Muslim Brotherhood was designated a "terrorist organization" by the Egyptian government in late 2013.
