SICK ISIS leaders have hatched diabolical plans to recruit wannabe 'serial killers' to terrorise innocents in the West.

The hate group is now urging extremists living in Europe and the US to carry out frequent and random knife attacks in cities, towns and villages.

They want their followers to buy a knife, slaughters innocents, then dispose of the knife and start over again.

In an article in the terror group’s Rumiyah magazine they even give advice on what types of knives to use - suggesting striking in secluded places after dark to avoid detection, reports the Daily Express.

They urge would-be jihadis to overcome their squeamishness by using knives instead of guns - because it is easier to carry out large numbers of murders without getting caught.

ISIS chiefs believe random serial killer-style stabbings are almost impossible for security services to detect compared to shootings and bombings, which require coordination and specialist equipment.

Commanders suggest a "campaign of knife attacks" in which lone-wolf jihadis "could dispose of his weapon after each use, finding no difficulty in acquiring another one”.

They wrote: "Many people are often squeamish of the thought of plunging a sharp object into another person’s flesh.

“It is a discomfort caused by the untamed, inherent dislike for pain and death, especially after 'modernisation' distanced males from partaking in the slaughtering of livestock for food and the striking of the enemy in war.

"However, any such squirms and discomforts are never an excuse for abandoning jihad.

“One need not be a military expert or a martial arts master, or even own a gun or rifle in order to carry out a massacre or to kill and injure several disbelievers and terrorise an entire nation."

And they even advise the kids of blades to use, saying: "It is explicitly advised not to use kitchen knives, as their basic structure is not designed to handle the kind of vigorous application used for assassinations and slaughter.

“Avoid troublesome knives, those that can cause harm to the user because of poor manufacturing."

A footnote in the article also betrays ISIS’ sensitivity about how their actions are reported in the West, insisting that supporters should not use the term “lone wolf” to describe radicalised Westerners.

Instead they order extremists to refer to such attacks as "just terror operations" - with just in this instance referring to the sense of justice the twisted barbarians see in them.
