Gunmen killed three Egyptian policeman and a civilian on Wednesday in the Sinai Peninsula, where the military is battling a jihadist insurgency, the interior ministry said.
The gunmen in a car intercepted a taxi carrying the policemen in the north Sinai capital El-Arish and killed them along with the driver, the ministry said in a statement.
Jihadists have killed hundreds of soldiers and policemen since the military overthrew Islamist president Mohamed Morsi in 2013.
They pledged allegiance to the Islamic State group more than a year later, and their attacks have persisted despite a sweeping military campaign in the peninsula, which borders Israel and the Gaza strip.
The jihadists have also targeted foreigners, claiming a 2015 bombing of a Russian airliner carrying holidaymakers home from a Sinai resort that killed all 224 people on board.
