Egyptian security officials say gunmen killed five Egyptian soldiers near the Suez Canal city of Ismailia on October 7.
The officials said the gunmen opened fire on the soldiers while they were sitting in a car at a checkpoint.
The attack occurred north of the city, where suspected militants have repeatedly targeted security forces in recent weeks.
In the capital, Cairo, unknown assailants fired rocket-propelled grenades at communication satellite dishes in Cairo, damaging one.
Meanwhile, a powerful car bomb hit a security forces' compound in the town of al-Tour in Sinai on October 7, killing at least two people and injuring 48.
The military has been conducting an extensive operation in the Sinai Peninsula east of the Suez Canal to crack down on Islamist militants, who have killed dozens of soldiers and policemen.
