CAIRO—Terrorists killed 184 people at a mosque in Egypt’s north Sinai region on Friday, detonating a bomb and shooting at fleeing worshippers and ambulances, state media and witnesses said.
It was one of the deadliest attacks in the region’s Islamic insurgency. No group claimed immediate responsibility, but since 2014 Egyptian security forces have battled a stubborn ISIS affiliate in the north of the mainly desert Sinai, where militants have killed hundreds of police and soldiers.
