Attack on mosque in Egypt´s Sinai kills at least 235

Cairo: Armed attackers on Friday killed at least 235 worshippers in a bomb and gun assault on a packed mosque in Egypt´s restive North Sinai province, state media reported, the country´s deadliest attack in recent memory.

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

Witnesses said the assailants had surrounded the mosque with all-terrain vehicles then planted a bomb outside.

The gunmen then mowed down the panicked worshippers as they attempted to flee and used the congregants´ vehicles they had set alight to block routes to the mosque.

State television reported at least 235 people were killed and 109 wounded in the attack, the scale of which is unprecedented in a four-year insurgency by extremist groups.

Egypt´s presidency declared three days of mourning, state television reported, as President Abdel Fattah al-Sisi met his security ministers to follow developments.

UK foreign minister Boris Johnson condemned the "barbaric attack" in a post on Twitter, while his French counterpart Jean-Yves Le Drian expressed his condolences to the families of victims of the "despicable attack".

Ahmed Abul Gheit, head of the Arab League, which is based in Cairo, condemned the "terrifying crime which again shows that Islam is innocent of those who follow extremist terrorist ideology," his spokesman said in a statement.

There was no immediate claim of responsibility for the attack.

The Daesh 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.

The victims included civilians and conscripts praying at the mosque.

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

Daesh 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 Daesh, Egypt also faces a threat from Al-Qaeda-aligned militants 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 militant who was a military officer before joining an Al-Qaeda-affiliated group in Libya´s militant stronghold of Derna.
