Up to 30 attackers carrying the Islamic State in Iraq and Syria (Isis) group flag massacred more than 300 people, including 27 children, at a mosque in northern Sinai in Egypt on 24 November.

It is understood to be the deadliest attack in the country’s recent history, with local media stations reporting a further 128 individuals had been wounded in the attack.

Egypt’s chief prosecutor Nabil Sadiq has said the attack was carried out by 25-30 militants, who stationed themselves at the mosque’s main door and 12 windows before opening fire on worshippers inside.

MEED understands the country’s military began responding on 25 November with multiple air strikes directed at “terrorist locations”.

The attack took place two years after a reported bomb on board a Russian passenger plane caused it to crash in the Sinai Peninsula shortly after taking off from Sharm el-Sheikh International airport, killing all 224 passengers on board.
