UPDATE: Egypt mosque attack death toll rises to 305

UPDATE (11/25/17):

Egypt's chief prosecutor says in a statement that the attack on a Sinai mosque has killed 305 people, including 27 children.

In a statement Saturday, Nabil Sadeq says the attack a day earlier also left 128 people wounded.

Sadeq says it was carried out by 25-30 militants who arrived at the mosque in the small town of Bir al-Abd in five all-terrain vehicles. He says the militants stationed themselves at the mosque's main door and 12 windows before opening fire on worshippers inside. They also torched seven cars belonging to the worshippers that were parked outside.

There was no claim of responsibility for the attack, the deadliest by Islamic extremists in Egypt's modern history. The mosque is frequented by Sufi Muslims, a mystic school of Islam that militants consider heretic.

Original story (11/24/17):

The U.N. Security Council and Secretary-General Antonio Guterres have condemned the deadly attack on a mosque in Egypt's Sinai Peninsula in "the strongest terms" and called for the perpetrators to be brought to justice.

Egyptian state news agency MENA is reporting that the death toll from the attack has risen to 235 people killed. The attack appeared to be the latest by the area's local Islamic State affiliate. It added that 109 people had been wounded.

The council statement called it a "heinous and cowardly terrorist attack" and reiterated that all acts of terrorism "are criminal and unjustifiable, regardless of their motivation." Guterres called the attack, which killed at least 235 people, "horrific."

The attack on the al-Rawdah mosque, largely attended by Sufi Muslims, in the town of Bir al-Abd, 40 km (25 miles) from the North Sinai provincial capital of El-Arish.

Officials said militants in four off-road vehicles bombed the mosque and fired on worshippers during the sermon segment of Friday prayers.

Security Council members, including Egypt which is serving a two-year term, "reaffirmed that terrorism in all its forms and manifestations constitutes one of the most serious threats to international peace and security."

Both the council and the secretary-general extended deepest condolences to the families of the victims and to the government and people of Egypt.

President Donald Trump also denounced the attack, calling it a "horrible and cowardly terrorist attack on innocent and defenseless worshippers in Egypt."

Trump says on Twitter that: "The world cannot tolerate terrorism" and that "we must defeat them militarily and discredit the extremist ideology that forms the basis of their existence!"
