CAIRO, April 7 (Xinhua) -- Two Egyptian policemen were killed Sunday and two others were injured by unknown gunmen in Nozah district, east of the capital Cairo.
In a statement, Egyptian Interior Ministry said the policemen, who were patrolling the area, doubted a parked black car with hand-written number plates in the distract.
As the policemen approached the car, the ministry said, the driver stepped out and opened machine gunfire at the policemen, killing a police officer and his driver.
Policemen began combing the area to arrest the gunmen and a probe was launched into the incident, according to the ministry.
The ministry did not announce if it was a terrorist attack.
Terrorism prevailed in Egypt since the military ousted former Islamist President Mohamed Morsi in early July 2013 in response to mass protests against his 12-month reign and his currently outlawed Muslim Brotherhood group.
Terror attacks killed hundreds of policemen and soldiers in restive North Sinai province northeastern Cairo before they gradually extended to other provinces, where dozens of civilians, mainly Christians were killed.
Most of the attacks were claimed by Sinai State group, which is based in Egypt's North Sinai province.
