This week saw Saudi Arabia announce a huge 34-state alliance tasked with wiping out ISIS militants - also known as Daesh - and other terrorist groups. Mohammed bin Salman, the Saudi defence minister, said the group - which will be headquartered in the nation’s capital city Riyadh - would fight terrorist activities in Iraq, Syria, Libya, Egypt and Afghanistan.

But now ISIS has threatened to hit back at the “morons and fools” of the coalition in a weekly publication documenting its activities. In an article titled ‘Mohammed bin Salman's alliance of surprised allies’, it said: “With permission from Allah, this alliance will be the beginning of the collapse of the governments of the oppressive tyrants in the lands of Islam.”

Announcing the alliance on Tuesday, Mr Salman described the group as an “international coordination with major powers and international organisations”.

We can't undertake these operations without coordinating with legitimacy Mohammed bin Salman

He added: "We can't undertake these operations without coordinating with legitimacy in this place and the international community." He confirmed the group will fight depraved ISIS jihadis, as well as "any terrorist organization that appears in front of us". The huge coalition combines Arab countries like Egypt, Qatar and the United Arab Emirates with Islamic countries like Malaysia, Pakistan and Turkey. Iran, which is at loggerheads with Saudi over influence in the Arab world, will not be part of the organisation.
