235 people have been killed in a bomb and gun attack on a mosque in Egypt's North Sinai province.
Witnesses say the al‑Rawda mosque in the town of Bir al‑Abed, near al‑Arish, was targeted during Friday prayers.
It is the deadliest attack of its kind since an Islamist insurgency in the peninsula was stepped up in 2013.
Egyptian President Abdul Fattah al‑Sisi vowed to respond with "brute force" after talks with security officials.
No group has yet claimed the attack, but militants affiliated with so‑called Islamic State have been responsible for scores of deadly attacks in the province.
They usually target security forces and Christian churches.
Witnesses said dozens of gunmen arrived in off‑road vehicles and bombed the packed mosque before opening fire on worshippers as they tried to flee.
