Militants have launched a bomb and gun attack on a mosque in Egypt's North Sinai province, killing 235 people.
One hundred and thirty others were injured.
The al-Rawda mosque in the town of Bir al-Abed was targeted during prayers on Friday.
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.
