CAIRO — Egypt’s Interior Ministry says gunmen have killed a captain from the intelligence services and a policeman on a desert road outside Cairo.

The ministry’s media center said the joint security patrol was trying to stop a suspicious vehicle on the road to the canal city of Suez early Sunday when its occupants opened fire.

Captain Ashraf Badeer al-Qazaz was killed in the firefight, along with a policeman from the central security force. The assailants managed to flee.

On Saturday, a militant group called Ajnad Misr, or “Egypt’s Soldiers,” claimed responsibility for a bombing that killed a police officer late Friday in Cairo. The group said it is waging a campaign of retribution for the killing and detentions of protesters and young Egyptians.
