At least 235 people have been killed and 109 injured after militants blew up a mosque in Egypt’s North Sinai province.

Police sources confirmed to the Associated Press that men in four off-road vehicles armed with explosives opened fire on worshippers inside the mosque during Friday prayers.

It is the deadliest terror attack in modern Egyptian history, surpassing the bombing of a Russian passenger jet which killed 224.

Egypt’s Health Minister told Al Jazeera TV that “there were many people inside the mosque — it’s only a small mosque.”

He added that the militants even shot worshippers fleeing the initial attack

President Abdel-Fattah el-Sissi declared three days of national mourning and called a meeting of security officials after the attack.
