Egyptian security forces killed 10 suspected militants Sunday in a shootout during a raid on two apartments in central Cairo.
At least 18 police forces, including a general, have been killed in Egypt's Sinai Peninsula after militants ambushed their convoy, in one of the deadliest terrorist attacks in the restive region since January. Four armored vehicles and a fifth carrying signal-jamming equipment were destroyed while a police pickup truck was commandeered, they said.
Police raided two apartments in Ard Ellewa district on a tip-off that terrorists were hiding there and preparing to launch attacks, the state-run MENA news agency reported.
The officials spoke on condition of anonymity because they were not authorized to speak to the media.
No group has claimed responsibility for Monday's attack, while the Egyptian authorities have yet to comment on the incident. It did not provide any casualty figures.
The attack illustrates how hard it is for the government to crush a militant campaign that has withstood a four-year crackdown.
Three policemen were injured after one suspected militant detonated an explosive device to block their entry into the building and two other policemen were injured during the exchange of fire that followed. They said the fighters had sneaked into the capital from northern Sinai but did not say whether they were members of ISIL.
Egypt has battled fighters in Sinai for years, but the rebellion became far more deadly after the 2013 military removal of Mohamed Morsi.
The Sinai - a triangular piece of land bordering southern Israel and the Gaza Strip - has emerged as the main battleground in the faceoff between Islamist militants and President Abdel-Fattah El-Sisi.
