CAIRO (AP) -- Egypt's military says one of its helicopters has crashed after a "sudden technical failure," injuring an undisclosed number of crew members.
A statement on Saturday's crash said the helicopter was on a reconnaissance mission northeast of Cairo in the Ismailia province. It did not say how many crew members were injured or how badly they were hurt.
Egypt has been battling a growing insurgency in the northern Sinai Peninsula led by a local Islamic State affiliate.
The militant group claimed responsibility for the crash of a Russian passenger plane in Sinai last month, saying it had smuggled a bomb on board the airliner.
Russia said the plane was downed by a bomb and suspended flights to Egypt. Egypt has not commented on the cause of the crash, saying an investigation is still underway.
