Ten Egyptian army members including an officer were killed or wounded on Thursday when a bomb exploded in an armored vehicle south of Bir al-Abd city in the Northern Sinai region, a military spokesman said in a statement.
He did not specify how many had been killed in the attack, which was not immediately claimed by any group. Militants loyal to the ISIS are active in the strategic border region.
Egypt has been fighting the insurgents who have killed hundreds of police and soldiers in the northern part of the Sinai Peninsula since the ousting of Mohamed Mursi of the Muslim Brotherhood in 2013 following mass protests against his rule.
Militants have also carried out attacks elsewhere in the country.
