Islamic State are determined to hit the west where it hurts.

Last December, a former Islamic State recruit known as Harry S, was arrested after returning to Germany from Syria.

He revealed how the terror group is planning more co-ordinated terror attacks across Europe, and detailed the shocking and brutal execution methods used by militants.

The German joined the militant group for three months last year but returned home after being sickened by the group’s beheadings and execution methods.

Harry S, who is remains in police custody in Germany, warned IS is planning co-ordinated terror attacks across Europe — “something that happens everywhere at the same time”.

He revealed how he and other foreign fighters were asked if they would “bring jihad to their homeland” Spiegel Online reported.

Harry S also revealed how the execution methods were beyond brutal and how he was encouraged to sleep with his gun.

German authorities remain on high alert following his arrest with security tight.

While the comments were made last year, it seems some of his warnings about co-ordinated attacks hitting Europe and European targets are have already come true.

Turkey has been hit by a series of IS-led attacks, and in January, 11 German tourists were killed after a suicide bomber affiliated with the IS detonated a bomb in Istanbul’s historic Sultanahmet district.

In October last year, suicide bombings blamed on IS targeted a peace rally outside the main train station in Ankara, killing 102 people in Turkey’s deadliest attack in years.

More than 30 people were killed in a suicide attack in the town of Suruc, near Turkey’s border with Syria, in July.

And Turkish authorities claimed they foiled a Paris-style terror attack in October last year.

DEATH BY BOMB:

Meanwhile shocking new images of the terror group’s brutal execution methods have emerged on social media.

The images shared by the terror group show militants brutally murder a so-called spy by tying explosives around his neck before blowing his head off.

The photos show a prisoner wearing an orange jumpsuit being forced to his knees as a blue rope is tied around his neck.

Moments later a group masked and heavily armed militants detonate the explosives, decapitating their Iraqi victim instantly, The Sun reported.

The dead prisoner was one of six men accused of spying killed in Islamic State’s latest release.

All of them are accused of leaking information to the Iraqi government about their military operations.

One of the victims is understood to be a doctor named Mohamed Mahmoud Dayih, who worked at a hospital in ISIS-held Fallujah.

Dayih had been accused of using his access to IS injured fighters, medical reports and knowledge of troop movements to send information to the Iraqi government.

The sick executions come as the US declared IS is committing genocide against the Christian, Yazidi and Shiite minorities on its territory in Iraq and Syria.

“Daesh is genocidal by self-proclamation, by ideology and by actions, in what it says, what it believes and what it does,” Secretary of State John Kerry said, using another name for ISIS.

“Daesh is also responsible for crimes against humanity against these same groups,” he added, using the US government’s preferred term for the group.

Washington’s senior diplomat made the ruling after the US Congress voted to designate the IS murders of religious minorities genocidal, a move with international legal implications.

The US is already leading a coalition of Western and Arab allies to strike ISIS targets from the air and to support Iraqi government and Kurdish and Syrian militia forces against the group.

Mr Kerry however warned his “moral statement” does not place the US under any new legal obligations, but the White House said it could back an international investigation.

“The United States will co-operate with independent efforts to investigate genocide,” President Barack Obama’s spokesman Josh Earnest said.

Washington does not recognise the International Criminal Court, but officials said US agencies will collect evidence and work with international partners as states seek a way to bring justice to bear.

A State Department official, speaking on condition of anonymity, said the genocide ruling would not itself change the rules for granting refugee status.

But he insisted Syrian asylum seekers are already being considered sympathetically because the IS group’s atrocities are long-known.

And, Kerry argued, the US is already doing its utmost to halt the slaughter by leading a coalition to “degrade and destroy” the group.

Through air strikes and support for local forces, the coalition has pushed IS from 40 per cent of the ground it once held in Iraq and 20 per cent in Syria, he said.

MURDER AND SLAVERY:

The IS group’s history of murdering journalists, aid workers and suspected “spies” has made it difficult to document its crimes in great detail.

But the group has itself issued propaganda videos showing the mass killing of prisoners.

And it has issued its own legal rulings pronouncing that captured non-Muslim women slaves may be raped by its fighters.

“We’ve not been able to compile a complete record, I think that’s obvious on its face,” Kerry admitted.

“But over the past months we have conducted a review of the vast amount of information gathered by the State Department, by the intelligence community, by outside groups.”
