An Egyptian interior ministry official was shot dead by gunmen on a motorbike, security officials and medics said.
General Mohammad Saeed died in hospital after he was shot in his head and chest, officials said, adding that the assailants fled after the attack.
“General Mohammad Saeed, head of the technical office of the minister of interior, was targeted by gunmen inside a car who shot him and fled,” said one of the officials, according to Reuters news agency.
Saeed was a police general and an aide to Interior Minister Mohammad Ibrahim, who survived an assassination attempt last year.
Islamist militants have stepped up attacks on security forces since the army toppled president Mohammad Mursi of the Muslim Brotherhood in July.
