A police officer was killed and three conscripts were injured in a double blast which targeted a police armoured vehicle in North Sinai’s al-Arish city early Wednesday, police sources said.
The explosion damaged a number of houses and set a shop ablaze, the sources said.
Security sources combed the area in search of the assailants.
Military forces meanwhile thwarted a “terrorist operation” targeting security forces in North Sinai, the military spokesman said in a statement on Wednesday.
Security forces were able to carry out a “preemptive strike” which left seven “terrorists” killed and destroyed two weapons warehouses, spokesman Mohamed Samir said.
Militancy inside Egypt has seen a significant rise since the military ouster of Islamist president Mohamed Mursi in July 2013, which was prompted by mass protests against his rule. Most attacks occur in North Sinai, targeting security forces. The attacks have left hundreds of security personnel killed.
The armed forces has launched an intensified crackdown in the Sinai Peninsula in response to the militancy.
Samir had earlier said that a total of 141 suspected militants have been killed in North Sinai in May.
