EL-ARISH, Egypt (CBSNEWS/AP) – Militants attacked a crowded mosque during Friday prayers in the Sinai Peninsula, setting off explosives, spraying worshippers with gunfire and killing at least 235 people in the deadliest ever attack by Islamic extremists in Egypt.

The attack targeted a mosque frequented by Sufis, members of Islam’s mystical movement, in the north Sinai town of Bir al-Abd. Islamic militants, including the local ISIS affiliate, consider Sufis heretics because of their less literal interpretations of the faith.

The ISIS affiliate has been waging a stepped-up campaign of violence in northern Sinai for years and has claimed deadly bombings on churches in the capital, Cairo, and other cities, killing dozens of Christians. It also is believed to have been behind the 2016 downing of a Russian passenger jet that killed 226.

But this was the first major militant attack on a Muslim mosque and the startling bloodshed eclipsed any past attacks of its kind, even dating back to a previous Islamic militant insurgency in the 1990s.

The militants opened fire from four off-road vehicles on worshippers inside the mosque during the sermon, blocking off escape routes from the area by blowing up cars and leaving the burning wrecks blocking the roads, three police officers on the scene said.

Victims including some 130 wounded were rushed to local hospitals, they added, speaking on condition of anonymity because they weren’t authorized to brief reporters.

No one claimed responsibility immediately following the attack, but ISIS has targeted Sufis several times in the area in the past, notably beheading a leading Sufi religious figure, the blind sheikh Suleiman Abu Heraz, last year and posting photos of the killing online.

President Donald Trump condemned the “cowardly” attack on Twitter, and took the opportunity to tout the need for a border wall and travel ban, even though his most recent ban doesn’t affect Egypt. He also said he would be speaking with Egypt’s president, Abdel-Fattah el-Sissi, later Friday.
