Egyptian forces in the Sinai have been struck again by terrorists.
In a separate attack, the interior ministry said "another terrorist group" targeted El-Masaeed checkpoint on Egypt's Ring Road, killing a police conscript during an exchange of fire with security forces.
According to officials, the attack in the city of el-Arish in the Sinai Peninsula was followed by smaller explosions.
Over the past years, militants have been carrying out anti-government activities and fatal attacks, taking advantage of the turmoil caused in Egypt after the democratically-elected president Mohamed Morsi was ousted by the military in July 2013.
The group then changed its name to Sinai Province after it pledged allegiance to the "Islamic State" (IS) militant group.
