Two bombs hit an armoured vehicle in the town of Sheikh Zuweid killing a noncommissioned officer and wounding three other soldiers, an army spokesman said in a statement on his official Facebook page.
In response, a military helicopter killed three “terrorist elements” in a car while fleeing the scene, he added.
North Sinai is at the heart of an insurgency that has killed hundreds of soldiers and police since 2013 when then-army chief Abdel Fattah al-Sisi ousted Islamist president Mohamed Mursi. Sisi was elected president last year.[pro_ad_display_adzone id=”10″]
There was no immediate claim of responsibility for the bombings. Sinai Province, a militant group that has declared allegiance to Islamic State, has claimed such attacks in the past.
