Gunmen shot dead an informer and a soldier and injured five other people, including two civilians, in an attack at a police checkpoint in the province of Menoufia north of Cairo, the director of the ambulance services said, according to Reuters.
MENA, the Egyptian state-run news agency, said another three policemen and two civilians were wounded in the attack early Sunday in the Nile Delta governorate of Menoufiya.
No armed group claimed responsibility for the attack and the authorities said they were still investigating.
Security forces are searching for the men in that area, about 80 km (50 miles) north of Cairo, one security source said.
Since the military coup that ousted President Mohamed Morsi, the first democratically elected President, Egypt has witnessed a wave of attacks mainly targeting security forces mostly in Sinai Peninsula by Sinai Province group, which is affiliated with the Islamic State (ISIS). Sometimes, there were attacks in central Cairo, its outskirts, and other places .
Hundreds of soldiers and policemen were killed since the outbreak of violence in 2013.
