Ten Egyptian soldiers, including one colonel, were killed on Friday in a suicide bomb attack on an army checkpoint in northern Sinai, security sources said.
The sources said two vehicles detonated while passing a checkpoint in an area between Rafah and Sheikh Zuweid.
Egypt is facing an Islamist insurgency led by Islamic State in North Sinai, where hundreds of soldiers and police have been killed since 2013, when the military ousted former president Mohamed Morsi after mass protests.
