However, the Ministry of Interior today said that 16 policemen, including 11 officers, were killed in the clashes.
Egyptian President Abdel-Fattah al-Sisi on Sunday urged security bodies to exert utmost efforts to hunt for the perpetrators of the Friday terrorist attack that left 16 policemen dead in the desert of Giza province.
The Interior Ministry said the shootout took place during a raid to arrest a number of suspected militants in the area.
The suspected militants tried to flee after the exchange of fire there, the sources said, and continued to fire at a second security unit called in for backup from atop neighboring buildings.
Authorities are fighting the Egyptian branch of the self-styled Islamic State terrorist group, which has increased its attacks in the north of the Sinai peninsula more than 500 kilometers (300 miles) away from the latest violence.

Security sources said the forces were ambushed during the raid.
"We learned with sorrow that yesterday (Oct. 20) many security forces who have been attacked by terrorists in the city of Giza in Egypt have lost their lives and were wounded", a statement said. The Muslim Brotherhood denies this. The attackers also used explosive devices.
Egypt has been battling an insurgency since 2013 when the military deposed Mohamed Morsi, Egypt's first freely elected president, in a coup.
Egypt has been under a state of emergency since bombings and suicide attacks targeting minority Coptic Christians killed scores earlier this year. It is blamed for the killing of hundreds of soldiers and policemen and has started to target other areas, including Egypt's Christian Copts.
In their statements, none of the militant groups claim any affiliation to the Muslim Brotherhood.
