Cairo: Masked gunmen on a motorcycle shot dead four Egyptian policemen south of Cairo on Saturday, the interior ministry said.
The gunmen opened fire on a police vehicle, killing those inside, in an area between the famed Giza pyramids west of Cairo and the Saqarra pyramids to the south, the ministry said in a statement.
The attackers` affiliation was not immediately clear.
Islamist militants have killed scores of policemen and soldiers, mostly in the Sinai Peninsula, since the army overthrew Islamist president Mohamed Morsi in 2013.
Attacks have also targeted policemen and government buildings in the capital, several of them claimed by an Islamic State group affiliate.
The extremists often claim that their attacks are retaliation for a police crackdown on Islamist protesters, which has killed hundreds and left thousands in prison since Morsi`s overthrow.
