One person was also injured in a critical condition, a security source said.
The incident came a day after four police and army personnel killed in two separate attacks in North Sinai yesterday.
The country has witnessed many violent attacks by militants since the January, 2011 revolution that toppled ex-president Hosni Mubarak.
The attacks targeting police and military increased after the ouster of Islamist ex-president Mohamed Morsi in 2013 by military following massive protests against his rule.
