ISIS has issued a chilling instruction to its followers to launch an "all-out war" on the West to mark the start of Ramadan tomorrow.

European security services are said to be bracing for more attacks during the Muslim holy month as ISIS's followers are urged to attack "infidels" in the wake of Monday's Manchester bomb attack.

The jihadist group made the call in a video message entitled Where are the lions of war? published on YouTube, reports The Telegraph.

It said: “Muslim brothers in Europe who can’t reach the Islamic State lands, attack them in their homes, their markets, their roads and their forums."

Millions of Muslims worldwide are preparing for Ramadan, a holy month of fasting and religious devotion.

Referring to Monday's attack, which saw 22 killed and dozens more injured, ISIS's statement reassured its followers.

The message said: "Do not despise the work. Your targeting of the so-called innocents and civilians is beloved by us and the most effective, so go forth and may you get a great reward or martyrdom in Ramadan."

ISIS claimed responsibility for the attack by Salman Abedi at the Manchester Arena on Monday.

Abedi blew himself up and security services have since been probing a potential terror network, with at least eight people in custody after raids across Manchester and the Midlands.

Sources suspect a car mechanic and infamous ISIS explosives expert may have trained Abedi to build a bomb.

At least 16 jihadists hail from a three-mile radius around the district where Abedi grew up — in Chorlton, Fallowfield, Didsbury and Moss Side.

British security services are said to fear another attack from Abedi's terror network as much as a copycat attack triggered by Monday's arena onslaught.

Yesterday the RAF scrawled a message on a missile destined for ISIS fiends that read “Love from Manchester”.

The defiant note was initially thought to be a social media hoax, but RAF bosses confirmed it was genuine.

Britain’s official terror threat level has been raised to “critical” by Theresa May after Abedi slaughtered 22 and injured dozens more on Monday night.

Major trauma centres across the country have been warned to prepare for a possible terror attack ahead of the Bank Holiday weekend.

Today it emerged the evil group may have deliberately rigged an Iraqi house filled with civilians with EXPLOSIVES before baiting the US into bombing the building.

A Pentagon investigation has concluded that at least 105 innocent people died in the American anti-terror strike in Mosul in March.

All 22 of Abedi's victims have now been named, with friends and families sharing emotional tributes to each.
