Absolutely outrageous. My heart cries for the victims and their families. Keep Egypt in your prayers and may the terrorists burn in an eternal hell. -LS
Militants have launched a bomb and gun attack on a mosque in Egypt's North Sinai province, killing 235 people, state media say.
The al-Rawda mosque in the town of Bir al-Abed 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 (IS) have been responsible for scores of deadly attacks in the province.
