Attack on mosque in Egypt's Sinai kills at least 115: state media

Gunmen attacked a packed mosque in Egypt's restive North Sinai province on Friday and set off a bomb, killing at least 115 people in one of the country's deadliest attacks in recent memory, state media reported.

A bomb explosion ripped through the Rawda mosque roughly 40 kilometers west of the North Sinai capital of El-Arish before gunmen opened fire on the worshippers gathered for weekly Friday prayers, officials said.

The official Al-Ahram newspaper reported on its website that at least 115 people were killed and 80 wounded in the attack, which is unprecedented in a four-year insurgency by Islamist extremist groups.

The Islamic State group's Egypt branch has killed hundreds of policemen and soldiers, and also civilians accused of working with the authorities, in attacks in the north of the Sinai peninsula.

They have also targeted followers of the mystical Sufi branch of Sunni Islam as well as Christians.

The victims included civilians and conscripts praying at the mosque.

A tribal leader and head of a Bedouin militia that fights IS told AFP that the mosque is known as a place of gathering for Sufis.

The Islamic State group shares the puritan Salafi view of Sufis as heretics for seeking the intercession of saints.

The jihadists had previously kidnapped and beheaded an elderly Sufi leader, accusing him of practicing magic which Islam forbids, and abducted Sufi practitioners later released after "repenting."

The group has killed more than 100 Christians in church bombings and shootings in Sinai and other parts of Egypt, forcing many to flee the peninsula.

The military has struggled to quell the jihadists who pledged allegiance to IS in November 2014.

IS regularly conducts attacks against soldiers and policemen in the peninsula bordering Israel and the Palestinian Gaza Strip, although the frequency and scale of such attacks has diminished over the past year.

They have since increasingly turned to civilian targets, attacking not only Christians and Sufis but also Bedouin Sinai inhabitants accused of working with the army.

Aside from IS, Egypt also faces a threat from Al-Qaeda-aligned jihadists who operate out of neighbouring Libya.

A group calling itself Ansar al-Islam -- Supporters of Islam in Arabic -- claimed an October ambush in Egypt's Western Desert that killed at least 16 policemen.

Many of those killed belonged to the interior ministry's secretive National Security Service.

The military later conducted air strikes on the attackers, killing their leader Emad al-Din Abdel Hamid, a most wanted jihadist who was a military officer before joining an Al-Qaeda-affiliated group in Libya's militant stronghold of Derna.
