Update: Egypt mosque attack: At least 235 killed in bomb blast, gunfire during Friday prayers

Militants killed 235 people at a mosque in Egypt’s north Sinai region on Friday, detonating a bomb and shooting at fleeing worshippers and ambulances, the state television reported, quoting the public prosecutor.

It was one of the deadliest attacks in the region’s Islamist insurgency. No group claimed immediate responsibility, but since 2014 Egyptian security forces have battled a stubborn Islamic State affiliate in the north of the mainly desert Sinai, where militants have killed hundreds of police and soldiers.
