Terrorists bombed a Sufi mosque and fired on worshippers in the Sinai Peninsula during Friday prayers.

At least 235 were killed, over 100 wounded in what appeared to be the latest attack by the region’s affiliate of the Islamic State.

The target was the al-Rawdah mosque in the town of Bir al-Abd, 40 kilometres from the North Sinai provincial capital of el-Arish.

While the ISIS affiliate is also thought to have been behind last year’s downing of a Russian jet that left 226 dead, this was the first major assault on a Muslim mosque.

The United Nations is condemning the incident, calling it a heinous and cowardly attack.

U.S. President’s Trump’s taken to social media, denouncing it on Twitter.

The lights of the Eiffel Tower will be turned off at midnight in homage to the victims.

Israel’s sent its condolences saying this is ”a time for international unity in the war on terror wherever it presents itself.”
