A police officer of the North Sinai security directorate force was killed in front of his house in Al-Arish early Sunday.
The Minister of Interior announced that Captain Abdullah Khalil was shot dead by masked assailants before they fled the area.
On Saturday, a blast in the neighbouring city of Rafah took the lives of two soldiers and injured two others as the ambush targeted the route of security forces, state media reported.
Insurgents have intensified attacks in North Sinai since the ousting of former Islamist president Mohamed Morsi in 2013. The governorate has become the scene of violent clashes between state militants and the Egyptian armed forces.
“State of Sinai”, formerly known as Ansar Beit Al-Maqdis, has claimed responsibility for the majority of the attacks against security forces in North Sinai.
